    Abstract

       This document is a revision to [RFC 1632]: A Revised Catalog of
       Available X.500 Implementations and is based on the results of data
       collection via a WWW home page that enabled implementors to submit
       new or updated descriptions of currently available implementations of
       X.500, including commercial products and openly available offerings.
       [RFC 1632] is a revision of [RFC 1292].  We contacted each
       contributor to [RFC 1632] to request an update and published the URL
       of the WWW home page survey template in several mailing lists to
       encourage the submission of new product descriptions.

    1.  Introduction

       This document catalogs currently available implementations of X.500,
       including commercial products and openly available offerings.  For
       the purposes of this survey, we classify X.500 products as,

          DSA

             A DSA is an OSI application process that provides the Directory
             functionality,

          DUA

             A DUA is an OSI application process that represents a user in
             accessing the Directory and uses the DAP to communicate with a
             DSA, and

          DUA Interface

             A DUA Interface is an application process that  represents a
             user in accessing the Directory using either DAP but supporting
             only a  subset of the DAP functionality or a protocol different
             from DAP to communicate with a  DSA or DUA.

       Section 2 of this document contains a listing of implementations
       cross referenced by keyword.  This list should aid in identifying
       implementations that meet your criteria.

       To compile this catalog, the IDS Working Group solicited input from
       the X.500 community by publishing a URL for a set of on-line
       description forms deployed on the WWW as a home page on an InterNIC
       server. This URL

    Apple & Rossen               Informational                      [Page 2]

    RFC 2116            X.500 Implementations Catalog-96          April 1997

       (http://www.internic.net/projects/x500catalog/catalogtop.html) was
       advertised on the following directory-related mailing lists:
       iso@nic.ddn.mil, isode@nic.ddn.mil, osi-ds@cs.ucl.ac.uk,
       ids@merit.edu, ietf-asid@umich.edu, mhs-ds@mercury.udev.cdc.com,
       nadf-l@ema.org, and dssig@nist.gov.

       Readers are encouraged to submit comments regarding both the forms
       and content of this memo.  New submissions are welcome.  Please
       direct input to the Integrated Directory Services (IDS) Working Group
       (ietf-ids@umich.edu) or to the authors.  IDS will produce new
       versions of this document when a significant number of substantive
       comments have been received or when significant updates and/or
       modifications to X.500-related standards documents have been
       ratified.  This will be determined by the IDS chairpersons.

    1.1  Purpose

       The Internet has experienced a steady growth in X.500 piloting
       activities. This document hopes to provide an easily accessible
       source of information on X.500 implementations for those who wish to
       consider X.500 technology for deploying a Directory service.

    1.2  Scope

       This document contains descriptions of both free and commercial X.500
       implementations.  It does not provide instructions on how to install,
       run, or manage these implementations.  The descriptions and indices
       are provided to make the readers aware of available options and thus
       enable more informed choices.

    1.3 Disclaimer

       Implementation descriptions were written by implementors and vendors,
       and not by the editors. We worked with the description authors to
       ensure uniformity and readability, but cannot guarantee the accuracy
       or completeness of the descriptions, nor the stability of the
       implementations.

    1.4  Overview

       Section 1 contains introductory information.

       Section 2 contains a list of keywords, their definitions, a cross
       reference of the X.500 implementations by these keywords and a table
       containing implementor name, implementor abreviation, and the page of
       this document on which the description begins for a particular
       implementor.

       Section 3 contains the X.500 implementation descriptions.

       Section 4 has a list of references.

       Section 6 lists the editors' addresses.

    1.5  Acknowledgments

       The creation of this catalog would not have been possible without the
       efforts of the description authors and the members of the IDS Working
       Group.  Our special thanks to the editors of [RFC 1632], Linda
       Millington and Sri Sataluri who graciously contributed the nroff
       source file used to structure their version of the catalog.

    2.  Keywords

       Keywords are abbreviated attributes of the X.500 implementations.
       The list of keywords defined below was derived from the
       implementation descriptions themselves.  Implementations were indexed
       by a keyword either as a result of: (1) explicit, not implied,
       reference to a particular capability in the implementation
       description text, or (2) input from the implementation description
       author(s).

    2.1  Keyword Definitions

       This section contains keyword definitions.  They have been organized
       and grouped by functional category. The definitions are ordered first
       alphabetically by keyword category, and second alphabetically by
       implementation name within keyword category.

    2.1.1  Availability

       Available via FTP

          Implementation is available using FTP.

    3.  Implementation Descriptions

       In the following pages you will find descriptions of X.500
       implementations listed in alphabetical order.  In the case of name
       collisions, the name of the responsible organization, in square
       brackets, has been used to distinguish the implementations.  Note
       that throughout this section, the page header reflects the name of
       the implementation, not the date of the document.  The descriptions
       follow a common format, as described below:

       A-Window-To-Directory is a simple-to-use DUA interface available on
       PC that provides access to the X.500 Directory Services. The
       available operations are: bind (authenticated or anonymous), read,
       list, compare, modify, modifyRDN, search, add, remove and unbind.  It
       is designed to be used with the Bull X500-DUA product and for that
       reason is able to handle any of the defined schema. The new acronyms,
       objects and attributes are automatically loaded without any
       customisation.  The interface of the application may be personalized
       in several ways, through Local Preferences stored on the PC and
       through User Settings stored on the UNIX machine that runs the Bull
       X500-DUA product.

    NAME

       Critical Angle X.500 Enabler

       (CAIx500e)

    ABSTRACT

       The X.500 Enabler product allows an LDAP-only directory server to be
       integrated into X.500 environments, by transparently converting X.500
       DAP and DSP requests into LDAP requests.

       The initial release scheduled for 4Q96 will allow for connections
       from X.500-capable clients and servers to an LDAP-capable server, and
       will support the following features:

          * LDAP version 2, as defined in RFC 1777,

          * all attributes defined for LDAPv2, with the exception of
            certificates  and revocation lists,

          * X.500(1988) DAP and DSP protocols over TCP/IP (using  RFC
            1006),

          * the following operations: Bind (with  none or simple
            credentials), Read, Compare, List, Search, Abandon, AddEntry,
            ModifyEntry, RemoveEntry and ModifyRDN,

          * the X.500(1993) critical extensions field, to aid in
            deployments incorporating 1993 DSAs.

       This release will be available for Solaris 2.5 (SPARC and Intel) and
       Windows NT 4.0 Server (Intel).

       The product is expected to enter a public beta test period in
       September 1996.  Beta test evaluation copies will be free (limited to
       two copies per site) but will be set to expire in December 1996.

       Released versions of X.500 Enabler will be licensed per server, and
       will be distributed over the Internet.

    COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

       The X.500 enabler accepts DAP and DSP connections.

       It supports Bind (with none or simple credentials), Read, Compare,
       List, Search, Abandon, AddEntry, ModifyEntry, RemoveEntry and
       ModifyRDN.

    Apple & Rossen               Informational                     [Page 34]

    RFC 2116            X.500 Implementations Catalog-96          April 1997

       It supports the attributes and object classes defined in X.520 and
       X.521.

    COMPLIANCE with X.500-1993 (applicable only for DSAs and DUAs)

       The X.500 Enabler will accept connections from X.500(1993) DUAs and
       DSAs.

       It supports the X.511(1993) critical extension mechanism.

       Non-critical protocol fields which do not map onto LDAPv2 are
       ignored.

       Attribute and object classes from X.520(1993) and X.521(1993) are
       supported, including collective.  Operational attributes from X.501
       are supported, with the exception of subschema.

       As LDAPv3-based servers become available, it is expected that the
       X.500 Enabler will be upgraded to map more of the X.500(1993)
       protocol onto LDAPv3.

    CONFORMANCE WITH PROPOSED INTERNET STANDARDS

       [RFC 1006] is the supported transport service.

       The product supports the object classes and attributes defined in RFC
       1274.

    CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL RFCs

       [No information provided. -- Ed.]

    INTEROPERABILITY

       The X.500 Enabler is being tested with public-domain X.500 and LDAP
       clients and servers, and with the various X.500 clients and servers
       connected to the PARADISE project, such as from the ISODE Consortium.

       Critical Angle intends to do interoperability testing with commercial
       LDAP-only servers as they become available.

    PILOT CONNECTIVITY

       This product will be used to connect LDAP-only servers, such as
       University of Michigan's slapd, and many vendor's forthcoming
       commercial LDAP server products, into the PARADISE project directory,
       so that they can be accessed by LDAP and X.500 DUAs throughout the
       project.

       Bugs reports may be sent to <bug-x500e@critical-angle.com>.

    CAVEATS AND GENERAL LIMITATIONS

       X.509 certificates and revocation lists are not supported due to
       limitations in the LDAP version 2 protocol. This restriction will be
       removed once LDAP version 3 servers become generally available.

       Under Windows NT there are limitations on the number of simultaneous
       incoming connections.

    INTERNETWORKING ENVIRONMENT

       This product supports RFC 1006 for DAP and DSP, and LDAP over TCP.

    HARDWARE PLATFORMS

       This product will initially be available for Sun Solaris 2.5 SPARC
       and Intel, and Windows NT Server 4.0 Intel.

       Subsequent versions may be available on additional platforms.

    SOFTWARE PLATFORMS

       An LDAP-based server, such as the freely-available slapd, is
       required.  It does not need to run on the same host as the X.500
       Enabler.

    ABSTRACT

       The CXDUA is a Windows 3.1 DUA that has been derrived from a highly
       portable and flexible Unix based Administrative Directory User Agent.
       The goal of the original design was to support features to assist a
       directory administrator in managing the directory.  These features
       include a highly portable GUI, Entry Templates, Entry Lists, Batch
       Operations and Directory Control Functions.

       Both the Windows and the Unix versions support strong authentication.

       The Unix DUA has been used in various DMS and NSA pilot projects.

    ABSTRACT

       DC X500 provides a truly scalable X.500 based enterprise directory
       server with the necessary architectural flexibility to enable
       integration with existing database and directory technologies.

       From a pure X.500 standpoint, DC X500 provides a full function
       state-of-the-art DSA implementation.

          * Architected from scratch according to the 1993 X.500
            standards (i.e. not a 1988 DSA with 1993 features grafted on)

          * Support for all the key X.500 OSI protocols:

             * Directory Access Protocol (DAP) for user access

             * Directory System Protocol (DSP) for distributed DSA
               comunications

             * Directory Information Shadowing Protocol (DISP) to support
               replication between servers to give improved performance
               in a distributed network

          * Support of the 1993 Basic Access Control and  Simplified
            Access Control models

          * Support for the key Internet  X.500 related standards:

             * integrated Lightweight DAP (LDAP)for DUA access

             * Madman MIBs for easy integration with SNMP

       The DC X500 architecture is based on Data Connection's underlying
       product architecture which has evolved since 1987 and includes:

             * genuine multi-threaded implementation

    Apple & Rossen               Informational                     [Page 42]

    RFC 2116            X.500 Implementations Catalog-96          April 1997

             * true  portability (the product is available on a range of
               operating systems e.g Windows NT, AIX, HP-UX. OS/2 etc and it
               is possible to port the core  technology to any
               hardware/software platform)

             * secure service recording for operation tracking and billing

             * support for system monitoring (both alarms and statistics)

       Key product features include:

             * Name resolution and integrated use of Search Indices based on
               2-3 trees leads to high performance operation evaluation
               (subsecond response times on  million entry DSAs)

             * Generic schema support based on 1993 concepts that allows
               customers to tailor the schema to meet their precise data
               structuing requirements

             * System recycle time is minimised (e.g. DC X500 can be backed
               up while running and  search indices are dynamically updated),
               helping achieve the goal of continuous (24x7) availability
               and high reliability.

             * No artificial software constraints are imposed resulting in a
               truly scalable product - assuming the availability of the
               necessary hardware DC X500 can be configured  to support
               millions of entries in a single DSA.

       DC X500 is certified for used within the Paradise Pilot project.  The
       product has also undergone interoperability testing at the EuroSInet
       interoperability workshops in Europe.

    NAME

       DE

    ABSTRACT

       DE (Directory Enquiries) is intended to be a simple-to-use DUA
       interface, suitable for the naive user, and suitable for running as a
       public access dua.  it will work on any terminal.  The user is
       presented with a series of (verbose) prompts asking for person's name
       department organization  country.  There is extensive on-line help.
       The matching algorithms are such that near matches are presented to
       the user before less good matches.

       There have been a few minor enhancements since the description in
       [RFC 1632].  The power searching feature still sets DE apart from
       most other DUAs - this allows a user to search for an entry even when
       they do not know the name of the organisation in which the person
       works - you still have to specify the country.  DE also allows UFN
       style searching.  DE uses slightly different search algorithms
       depending on whether it is accessing part of the Directory mastered
       by a Quipu DSA - Quipu DSAs tend to use lots of replication and so
       encourage searching.  DE incorporates a QOS feature where it
       maintains a database of past information availability and DSA
       responsiveness.  Translations exist into at least 4 different
       languages.

       DE runs over ISODE DAP and University of Michigan LDAP.  There is a
       version of DE, called DOS-DE, which has been ported to DOS, and this
       uses LDAP.

       DE was funded by the COSINE PARADISE project, and DE is used as the
       PARADISE public access dua. You can test the software by telnet to
       directory.ja.net and logging in as dua -- no password required.

    CAVEATS AND GENERAL LIMITATIONS

       DE tries to cater well for the general case, at the expense of not
       dealing with the less typical.  The main manifestation of this is
       that the current version does not handle searching under localities
       very well.

       It can handle photographs and reproduce sound attributes if these are
       dealt with by ancillary programs.

    ABSTRACT

       The Digital X.500 Directory Services product set includes a directory
       server product and a variety directory user agents, as well as a
       directory synchronizer utility.

       The Digital X.500 Directory Server product provides a high
       performance DSA implemented according to the 1993 edition of the
       standard. The InfoBroker Server product extends this to provide the
       server component for LDAP and WWW user agents.  Features of these
       servers include:

             * Integrated multi-protocol support allowing concurrent DAP,
               DSP, DISP and DOP access over OSI and TCP/IP (using [RFC
               1006]) protocols.

             * Indexed database (DIB) to support high-performance searching
               and sophisticated matching including approximate match.

             * A DIB based on the 1993 edition Extended Information Models.

             * Support for chaining and referrals in support of a
               distributed DIB

             * Support for the 1993 edition Basic Access Control scheme.

             * Configurable schema based on the 1993 edition (including
               attributes, object classes, structure rules, name forms).

             * Support for 1993 edition Shadowing using the DISP and DOP
               protocol, including both incremental and on-change features
               for high performance.

             * Remote management to control DSAs and log significant events.

             * Support for the LDAP protocols using the InfoBroker Server
               product across either TCP/IP  or DECnet transport protocols.

             * A Look-up Daemon that accepts requests from Web Browsers,
               allowing access to the directory from any web browser.

             * Both X/OPEN XDS/XOM and LDAP APIs.

       The Digital X.500 Administration Facility, X.500 Information Manager
       and InfoBroker Client products provide MS-Windows, Motif and command
       line interfaces to access and manage the information stored in the
       X.500 directory, including:

             * Support for different ways of accessing the directory, either
               by browsing or searching based on an  extensible set of
               filters.

             * Support for bulk load, unload and reload of entries.

             * Driven off the same configurable schema information as the
               DSA allowing extensibility of window layouts and text to
               support customer-defined object classes and attributes.

       The Synchronizer-500 is an X.500 DUA which:

       * Enables bi-directional synchronization between X.500 and
         virtually ANY other non-X.500 directory facilitating common
         management.

       * Maps incoming data into X.500 using flexible configuration
         files

       * Facilitates creation of a multivendor electronic mail
         database, creating addresses in the appropriate syntax for
         any mail system.

       * Provides uniqueness checking on mnemonic O/R addresses,
         preventing address duplication

    COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

       The Digital X.500 Directory Services products are based on the 1993
       edition standard. They are compatible with, and interwork with, 1988

    ABSTRACT

       DIR.X V3.1 is Siemens Nixdorf's Directory Service product compliant
       with the 1988 ITU-T X.500 recommendations. Siemens Nixdorf has
       supplied its Directory Service product as the GDS (Global Directory
       Service) component to OSF DCE.  However, DIR.X V3.1 has a number of
       features and enhancements which are not available in the GDS
       component of OSF DCE.

       DIR.X V3.1 is a distributed, replicated Directory Service. It
       consists of DSA, DUA and a tools package including comfortable
       administration and management utilities. DIR.X implements the
       protocol stack ranging from LDAP, DAP, DSP over ACSE, ROSE,
       Presentation, Session down to [RFC 1006]. On transport layer it
       supports TCP/IP and OSI LAN/WAN protocols.

       Data stored by DIR.X can be accessed via

          * the MS-Windows user interfaces DIR.D/ORG.D which are
            available as separate products from Siemens Nixdorf

          * any third-party LDAP or DAP browser

          * directory applications using the standardized X/Open XDS/XOM
            APIs (Directory Service / OSI Abstract Data Manipulation).
            The Siemens Nixdorf implementation was the first to gain
            XPG4-certification.

          * a command-line administration program

          * a menu-driven administration  program

          * WWW

          * a shell interface

          * the Query-by-mail interface of SNI's directory
            synchronization product DIR.X-SYNC

       DIR.X enables

          * The storage of globally-unique, tree-like name structures
            which can be mapped onto organizations.

            the same directory entry.

          * Search queries that allow the user to select objects on the
            basis of specific attributes and their values, as with a
            "Yellow Pages" telephone directory

          * Treemanagement functions which can cover entire subtrees.

          * The creation and automatic updating of copies ("shadows")
            from remote computers.

          * Access protection at attribute level, which regulates access
            on an object-specific basis.

          * The storage of unstructured attributes (graphics, pixels).

       The tools package of DIR.X V3.1 includes:

          * gdssetup: A simple-to-use tool for the generation and
            initialization of a directory configuration.

    NAME

       DIR.X (tm) V4.0 Siemens Nixdorf Informationssysteme AG

    ABSTRACT

       DIR.X V4.0 is Siemens Nixdorf's Directory Service product compliant
       with the 1993 ITU-T X.500 recommendations. The implementation
       incorporates SNI's experience of 10 years development, support and
       maintenance of the DIR.X products conformant to the 1988 Directory
       Standards, and has the following main features:

          * It conforms to the 1993 Directory standards, with particular
            emphasis on the requirements for interoperability with other
            X.500 implementations

          * The implementation is scaleable: it handles small-scale
            workgroup directories as well as very large directories for
            backbone solutions in large organisations

          * The implementation is extensible: new functionality can
            easily be incorporated

          * Existing databases and proprietary directory services can be
            accessed or integrated with the implementation.

          * Particular emphasis is placed on ease of administration of
            the Directory Service a service based on DIR.X V4.0 can be
            administered effectively from a central site, including the
            management of configuration and monitoring options

          * The implementation has a high throughput performing well not
            only on small systems, but also on high-performance backend
            servers, handling hundreds of requests in parallel on a
            multiprocessor machine.

       DIR.X V4.0 is a distributed, replicated Directory Service. It
       consists of:

          * DSA

          * DUA

          * Command-line DUA using a TCL (Tool Control Language) shell
            interface (dirxcp)

          * Management centre (dirxadm)

    NAME

    DIR.X-SYNC (tm) V2.0 Siemens Nixdorf Informationssysteme AG

    ABSTRACT

       DIR.X-SYNC V2.0 enables the synchronization of existing e-mail
       address directories in the X.500-based DIR.X directory service. The
       standard DIR.X, DIR.X-SYNC and DIR.D (all available from Siemens
       Nixdorf) products are the foundations on which the corporate
       directory solutions can be tailored to meet the customer's needs. The
       corporate directory then becomes the universal information system
       within the company.

       The user can access corporate directory information in different
       ways:

          * Using DIR.D, SNI's Windows client for the X.500 service, PC
            users can gain easy access to the DIR.X server containing the
            corporate directory data. The data found can  be transferred
            to other applications by means of DDE, drag and drop or cut
            and paste. (See DIR.D V2.6 for further information).

          * Query by mail: Authorized users can access data stored in the
            central or distributed directory system over their own mail
            system. DIR.X-SYNC retrieves the inquiry transmitted by mail
            and directs it on to the X.500 service. The search results
            are then delivered back to the user by mail. Using a WWW
            interface based on TCL scripts

       Query by mail does not require additional software on the end system.
       Each mail system connected to the X.400 backbone (e.g. MS-Mail,
       cc:Mail etc.) can use this function. DIR.X-SYNC currently supports
       the address formats of the following e-mail systems:

          * MAIL.X-OD V2.3

          * MAIL.2000 V1.2, AKOM

          * MS-Mail

          * cc:Mail

          * Intelligent Messaging Mail (Banyan)

    Apple & Rossen               Informational                     [Page 74]

    RFC 2116            X.500 Implementations Catalog-96          April 1997

       The standardized ISO-10021 interface for X.400 addresses is
       supported, enabling need for extension. This means that any type of
       system capable of generating this format (e.g. WordPerfect, Lotus
       Notes) can be connected. Address acknowledgment is carried out in ISO
       format.

       Functions for the administrator:

          * Export: Addresses can be exported from local directories.
            They are delivered as mail messages in ASCII format to the
            DIR.X-SYNC server.

          * Upload: The upload server stores the exported local addresses
            in DIR.X as globally valid X.400 addresses.

          * Query by Mail: DIR.X-SYNC enables mail members to send a
            search to the DIR.X-SYNC server by e-mail. Using this
            function, authorized administrators of the synchronized
            directories can acquire copies of the corporate directory
            data.

          * Administration of the DIR.X-SYNC server with an
            administration tool which can be used via command line or a
            command file.

       Other features include:

          * Replication and distribution: In addition to the central
            solution with a single corporate directory server, DIR.X-SYNC
            also supports replicated or distributed data storage in
            DIR.X-SYNC server.

          * Authentication/Authorization: To prevent unauthorized use of
            the corporate directory system, the O/R addresses of the
            authorized administrators and users are configured by the
            DIR.X-SYNC administrator. When a query by mail or an update
            arrives, the sender address is compared with this address.

          * Logging: In the case of error, e.g. incorrect file format,
            the sender (and the administrator  configurable) are informed
            of the fault by mail. At the same time, the error message is
            saved in a log file for the DIR.X-SYNC administrator. In
            addition, a "history  file" enables the monitoring of the
            uploads that have run or are currently running

    NAME

       Forum LOOK'UP (tm)

       Telis Systemes & Communications

    ABSTRACT

       Forum LOOK'UP (tm) is a Corporate directory solution based on the
       X.500 recommendations. It includes:

          * a Directory System Agent (DSA),

          * Directory User Agents (DUAs).

          * local network connections

          * remote workstation access

          * a WEB and videotex access

          * data  updating tools

          * a directory editing tool

       Forum LOOK'UP is a product based on PIZARRO, the research prototype
       developed at INRIA by Christian Huitema's team, and commercialized by
       Telis, a member of the France Telecom group.

       Characteristics of the DSA are:

          * The DAP and DSP protocols are provided conformant with X.500
            (88).

          * The DIB is maintained in ASN.1 encoded format in the Unix
            file system.

          * Utilities are provided to load and dump the DIB from and to
            ASCII text files.

          * As an option, an ORACLE V7 database can also be used.

          * The DIT structure is held in main memory. Frequently used
            attributes may be held in inverted tables in memory to speed
            up searches.

          * Knowledge management: knowledge on managed domains is stored
            in Forum LOOK'UP specific attributes of the DSA entries.

    Apple & Rossen               Informational                     [Page 80]

    RFC 2116            X.500 Implementations Catalog-96          April 1997

          * Schema: The X.500 (88), X.400 (88) and most of the Cosine and
            Internet Schema are supported. Object class and attribute
            definitions are enforced. Users may define their own.

          * Simple authentication is provided strong authentication and
            signed operations have been tested operationally through
            Telis's participation in PASSWORD, a VALUE project with aim
            to pilot a European security infrastructure for network
            applications.

          * Access control : the DSA offers a mechanism defined by Telis
            that is functionally equivalent to a profile of the X500 '93
            access control mechanism. The mechanism is based on the
            notion of administrative domains (autonomous and semi-
            autonomous). A domain defines the user groups (categories)
            and their access rights (consult, modify) to specified
            attribute types. The access rights are defined in
            prescriptive and entry ACI attributes.

          * Phonetic searches : administrators may specify a language
            (English, French, ...) for a subtree of the DIT. Approximate
            (phonetic) searches will then be carried out in the given
            language. The software loads a rule database to which new
            languages and new rules may be added easily.

          * Management: a Forum LOOK'UP DSA object has been defined to
            allow operational parameters of the DSA to be managed via
            DAP. Forum LOOK'UP conforms to X.500 (88) as specified in
            poaragraph 9 of X.519 Administration tools are provided :

          * to generate usage statistics automatically and distribute
            these by mail to administrators

          * to replicate subtrees of the DIT to other FORUM LOOK'UP
            DSAs and automatically update shadow copies,

          * to extract hardcopy listings from the database in an Excel
            compatible format for "paper" directories, all the
            management tasks are performed through a GUI (X/Motif).

          * The GUI includes a "dashboard" for monitoring of servers and
            the hardware they are installed on.

          * The DUAs include a graphical directory browser with powerful
            search functionality for PCs and Macintosh.

    CAVEATS AND GENERAL LIMITATIONS

          * The DIT structure and inverted attribute tables are stored in
            main memory.

          * The recommended main memory size for a DSA is 1kb per node,
            i.e., 10 Mb for a database of 10,000 objects.

          * The current recommended maximum for the proprietary database

    INTERNETWORKING ENVIRONMENT

       Forum LOOK'UP includes a transport stack for TP0 with TCP/IP [RFC
       1006] and X.25. The stack has been ported to SunNet OSI for TP4 with
       CLNP.

       DUAs on a LAN (Novell Netware, Microsoft Lan Manager, IBM Lan Server)
       can access the DSA without the need for IP on every Workstation. A
       module (called SOLO server) available on Novell, OS/2 and UNIX allows
       to have an IP or X.25 stack only on the file server. It is in charge
       of forwarding the request to a DSA.

       A direct access (DUA / DSA) through IP, X.25, PSTN or ISDN is also
       available.

    HARDWARE PLATFORMS

       Forum LOOK'UP can easily be ported to any UNIX machine.

       It currently runs on: Sun Solaris and Hewlett Packard.

       A port on IBM AIX is to be completed.

    SOFTWARE PLATFORMS

       The Forum LOOK'UP server is portable to any UNIX-like operating
       system.  X/Motif is the interface used for management.

       The DUAs are available on Windows and Macintosh.

       ORACLE V7 can be used as a database (option).

    NAME

       FX*500

       Firefox International Limited

    ABSTRACT

       FX*500 is a core component of Firefoxs product suite for mail,
       messaging and directories.

       FX*500 provides a Directory System Agent (DSA) which adheres to the
       latest 1993 X.500 standards.

       FX*500 may be used in conjunction with the Firefox FX*400 messaging
       products or may be combined with a range of Directory User Agent and
       Gateway products in order to satisfy a broad range of directory
       requirements.

       FX*500 affords unique integration opportunities with Novell's NetWare
       Directory Service (NDS) by offering the option of true dynamic
       directory integration between NDS and X.500.

       FX*500 provides support for key features of the X.500 1993 standard
       while continuing to support interworking with 1988 based directory
       user agents and system agents. The main 1993 features of X.500
       supported by FX*500 are:

          * Basic Access Control

          * The 1993 DSA Information Model

          * Replication and Shadowing

       In summary, FX*500 supports:

          * 1988 and 1993 X.500 Directory Access Protocol (DAP)

          * 1988 and 1993 X.500 Directory System Protocol (DSP)

          * 1993 X.500 Directory Information Shadowing Protocol (DISP)

          * 1993 Basic (or Simplified) Access Control

          * the Lightweight Directory Access Protocol (LDAP), as defined
            by [RFC 1777]

    Apple & Rossen               Informational                     [Page 85]

    RFC 2116            X.500 Implementations Catalog-96          April 1997

          * configuration of knowledge information for distributed
            operation using 1993 operational attributes

          * local management services, including a knowledge
            configuration application and extensive diagnostic facilities

          * an extended set of management applications

          * operation in a wide variety of network environments including
            connectivity over X.25, TCP/IP [RFC 1006] and OSI LANs.

          * an application developer's toolkit

       The optional application developer's toolkit includes:

          * the X/Open Directory Services (XDS) API to support directory
            user agent applications

          * a Gateway (G-XDS) API which is based on a simplified version
            of the XDS API syntax and allows developers to implement
            gateways to existing/ proprietary directory databases

          * a Network Management Interface (NMI) to support management
            applications and integration with management services.

       FX*500 is delivered with a schema defined to support the Common Use
       and MHS (X.402) Schemas defined by UK GOSIP V4. The subschema for
       FX*500 can be modified by the customer and updated dynamically.

       FX*500 provides for search optimisation by supporting keyed search
       whereby specific attributes can be identified as 'keyed' through
       local configuration data. This optimisation avoids the need to do a
       "brute force" search which requires a traversal of all the nodes of a
       subtree. Approximate match search filters are also supported by using
       a phonetic search based on the "Soundex" algorithm.

    COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

       FX*500 meets both the static and dynamic requirements implied by
       section 9.2 of X.519 1988.

       From section 9.2 of X.519 1988 regarding DSA conformance:

          * FX*500 supports both the directoryAccessAC and
            directorySystemAC application contexts.

    INTERNETWORKING ENVIRONMENT

       FX*500 utilises the Firefox FX*STACK product to provide an OSI stack
       for use over local or wide-area networks.  This enables the X.500
       DAP, DSP and DISP protocols operate over a range of different network
       types. The current network options are:

          * OSI LANs are supported by Transport Class 4 over CLNP (ISO
            8473), including the ES-IS routing protocol.

          * X.25 networks are supported in either a Connection-Oriented
            Network Service (CONS) or a Connection-Less Network Service
            (CLNS) environment.

             * For CONS, Transport Classes 0, 2 and 4 are supported over
               X.25(1984).

             * For CLNS, Transport Class 4 is supported over CLNP (ISO
               8473) utilising X.25 as a subnetwork.

          * TCP/IP networks are supported by an implementation of [RFC
            1006], which supports Transport Class 0 over TCP/IP.

    NAME

       ISODE Consortium Release 3.0 X.500(1993) Directory ISODE Consortium
       Ltd.

    ABSTRACT

       This implementation is a source release of an X.500(1993) Directory
       System Agent (DSA). It has been designed an implemented as an X.500
       1993 DSA not as a 1988 DSA with '93 extensions.  Emphasis has been
       placed on providing support for a flexible information model, access
       control, X.509 security features, and standard replication.

       The 1993 DSA offers a strong technical foundation on which to build
       an information and messaging infrastructure that relies on robust and
       scalable directory services. The implementation of this DSA
       incorporates the experience gained through the development, support,
       and maintenance of the earlier QUIPU, as well as operational
       experience and standards support.

    COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

       The DSA is aligned to the 1988 ISO IS and the NIST OIW Directory
       Implementors Guide Version 1. X.500(1993) features such as
       replication, access control, as well as X.509 certification are also
       available.  Interoperability testing with other DSAs has been
       performed.

    COMPLIANCE with X.500-1993 (applicable only for DSAs and DUAs)

       Please contact the ISODE Consortium if you wish to obtain our
       protocol information conformance statements. PICS may also be
       available from member organizations for their binary products.

    INTEROPERABILITY

       Interoperability with several other DSAs has been demonstrated in
       pilot operation and at Eurosinet in October 1995.

       At Eurosinet, X.500 interoperability testing used the X.500 DAP
       (Directory Access) and DSP (Directory System) protocols. Successful
       testing was done between the ISODE Consortium X.500(1993) DSA and
       DSAs from four other vendors including Siemens-Nixdorf and Bull. The
       ISODE Consortium was the only vendor to bring an X.500(93) compliant
       DSA to the workshop for the scheduled X.500(93) testing.

    PILOT CONNECTIVITY

       Connectivity to the global research pilots (PARADISE etc.) has been
       demonstrated. It is expected that this system will be used
       extensively in a wide range of pilot activities.  DUA Connectivity,
       and DSA Connectivity.

    BUGS

       Bugs should be reported to the ISODE Consortium via email.

    CAVEATS AND GENERAL LIMITATIONS

       None

    INTERNETWORKING ENVIRONMENT

    NAME

       LDAP

       University of Michigan

    ABSTRACT

       UM-LDAP is an implementation of the Lightweight Directory Access
       Protocol. LDAP is a draft Internet standard directory service
       protocol that runs over TCP/IP. It can be used to provide a stand-
       alone directory service, or to provide lightweight access to the
       X.500 directory.  LDAP is defined by [RFC 1777] and [RFC 1778].

       The UM-LDAP package includes the following components:

          * slapd - a stand-alone LDAP directory server

          * slurpd - a stand-alone LDAP replication server

          * ldapd - an LDAP-to-X.500 gateway server

          * centipede - an LDAP centroid generation and maintenance
            program

          * libldap - an LDAP client library

          * liblber - a lightweight BER/DER encoding/decoding library

          * ldif tools - data conversion tools for use with slapd

          * in.xfingerd - a finger-to-LDAP gateway server

          * go500 - a gopher-to-LDAP gateway server for searching

          * go500gw - a gopher-to-LDAP gateway server for searching and
            browsing

          * rcpt500 - an email-to-LDAP query responder

          * mail500 - an LDAP-capable mailer

          * fax500 - an LDAP-capable mailer that supports remote printing

          * LDAP tools - A collection of shell-based LDAP utility
            programs

    RFC 2116            X.500 Implementations Catalog-96          April 1997

       In addition, there are some contributed components:

          * web500 - an HTTP-to-LDAP gateway

          * whois++d - a WHOIS++-to-LDAP gateway

          * saucer - a simple command-line oriented client program

       The latest information about LDAP can always be found on the LDAP
       Home Page at this URL:

       http://www.umich.edu/~rsug/ldap/

    COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

       The U-M LDAP distribution is a complete implementation of the LDAP
       protocol.  The LDAP protocol does not support access to all X.500
       features and operations.  The operations supported are bind, search,
       compare, add, delete, modify, modify RDN, and abandon.  Note that
       read and list operations can be emulated using the search operation.
       Size and time limits may be specified, as may alias dereferencing and
       searching, but all X.500 service controls are not supported.

    COMPLIANCE with X.500-1993 (applicable only for DSAs and DUAs)

       Since the LDAP protocol itself has not yet been updated to support
       any 1993-specific X.500 features, this implementation does support
       any 1993 features yet either.

    CONFORMANCE WITH PROPOSED INTERNET STANDARDS

       Believed to be compliant with:

          [RFC 1274], [RFC 1777], [RFC 1778], [RFC 1779], [RFC 1781]

    CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL RFCs

       Includes an implementation of the LDAP API, as defined in [RFC 1823].
       Search filters used within UM-LDAP comply with [RFC 1558].

    INTEROPERABILITY

       The current implementation of the X.500-backended LDAP server (ldapd)
       is known to work with ISODE-based DAP libraries and the QUIPU DSA.

    PILOT CONNECTIVITY

       DUA connectivity should be possible to all pilots.

    BUGS

       Bug reports should be sent to bug-ldap@umich.edu.

    CAVEATS AND GENERAL LIMITATIONS

       None, aside from those mentioned above under completeness.

    INTERNETWORKING ENVIRONMENT

       LDAP clients use TCP to communicate with the LDAP server.  The LDAP
       server normally uses [RFC 1006] with TCP/IP to communicate with the
       DSA, though any other transport mechanism for DSA communication
       supported by ISODE should be possible.

    HARDWARE PLATFORMS

       The complete UM-LDAP package has been ported to a wide variety of
       UNIX systems, including: Sun3 and SPARCs running SunOS 4.1.x or
       Solaris 2.x, DECStations running Ultrix 4.3, HP 9000 series running
       HP-UX 9.05, IBM RS6000 running AIX 3.2.5, PCs running SCO, FreeBSD,
       NetBSD, or LINUX, DEC Alphas running OSF/1, and NeXTStatios running
       NeXTSTEP 3.2.  The complete package has also been ported to VMS.  In
       addition, the LDAP client libraries and some client programs have
       been ported to Apple Macintosh and PCs running MSDOS or Windows.

    SOFTWARE PLATFORMS

       The complete UM-LDAP package has been ported to a wide variety of
       UNIX systems, including: SunOS 4.1.x, Solaris 2.x, Ultrix 4.3, HP-UX
       9.05, AIX 3.2.5, SCO, FreeBSD, NetBSD, LINUX, OSF/1, and NeXTSTEP
       3.2.  It has also been ported to VMS.  In addition, the LDAP client
       libraries and some clients have been ported to Macintosh (System 7),
       MSDOS (some TCP/IP stacks), and Microsoft Windows 3.1, 95, and NT.

    NAME

       maX.500 :: Macintosh DUA Interface

       University of Michigan

    ABSTRACT

       maX.500 is a Directory User Agent (client) for Apple Macintosh.  It
       is widely used within Paradise and other Internet X.500 pilots.
       maX.500 supports searching, browsing, and modifying directory
       entries.  Display of textual information, playing of audio, and
       viewing of both black-and-white (fax) and color (JPEG) images are
       supported.  Communication with directory servers is via the
       Lightweight Directory Access Protocol (LDAP) over TCP/IP.  maX.500
       works both with standalone LDAP directory servers (such as slapd) and
       with X.500-backended LDAP servers (such as ldapd).

       maX.500 is a native Macintosh application, and has a friendly
       interface.  It requires System Software version 6.0.5 or later and
       Apple's MacTCP or Open Transport TCP/IP networking. The current
       version of maX.500 is 2.0.2, although version 2.1 is in beta test.

       The latest information about maX.500 can always be found on the
       maX.500 Home Page at this URL:
       http://www.umich.edu/~rsug/ldap/max500/

    COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

       maX.500 works over LDAP, and is subject to LDAP's limitations.  The
       bind, search, compare, add, delete, abandon, modify, and modifyrdn
       operations are all used by maX.500. Size and time limits may be
       specified, as may alias dereferencing control.

    COMPLIANCE with X.500-1993 (applicable only for DSAs and DUAs)

       maX.500 currently uses LDAP as defined in [RFC 1777], which does not
       support any 1993-specific X.500 features.

    CONFORMANCE WITH PROPOSED INTERNET STANDARDS

          Believed to be compliant with:

          [RFC 1274], [RFC 1777], [RFC 1778], [RFC 1779], [RFC 1781]

    Apple & Rossen               Informational                    [Page 112]

    RFC 2116            X.500 Implementations Catalog-96          April 1997

    CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL RFCs

       Search filters comply with [RFC 1558].

       Uses the LDAP API, as defined in [RFC 1823].

    INTEROPERABILITY

       maX.500 is known to work with the U-M LDAP servers (ldapd and slapd).
       It has also been tested with other commerical LDAP servers, such as
       Control Data's server.  maX.500 has been used with a wide variety of
       DSAs (always through an LDAP server).

    PILOT CONNECTIVITY

       DUA connectivity should be possible to all pilots.

    BUGS

       Bug reports should be sent to max500-bugs@umich.edu.

    CAVEATS AND GENERAL LIMITATIONS

       maX.500 does not support modification of "photo" (fax), "jpegPhoto",
       or "audio" attributes.  Versions of maX.500 before 2.1 did not
       support a fully functional browse facility.

    INTERNETWORKING ENVIRONMENT

       maX.500 is an LDAP client, and as such is uses TCP to communicate
       with the LDAP server.  Apple's MacTCP control panel or Open Transport
       TCP/IP networking is required.

    HARDWARE PLATFORMS

       maX.500 runs on Apple Macintosh Plus or later Macintosh computers,
       including PowerMacs. It requires 600K of free RAM.

    SOFTWARE PLATFORMS

       maX.500 requires Apple System Software 6.0.5 or later (System 7
       preferred) and MacTCP 1.1 or later (2.0.6 preferred).  maX.500 2.1,
       which is currently in beta test, will run natively on the PowerMac
       and use the native Open Transport networking interface if it is
       installed.

    NAME

       NonStop Directory Services (NSDS)
       Tandem Computers, Inc.

    ABSTRACT

       The Tandem NonStop Directory Services (NSDS) product provides a
       distributed open directory service on Tandem platforms.  It is an
       industrial strength implementation incorporating the Tandem product
       fundementals of resilience, linear extensibility, fault-tolerance, and
       continuous availability. NSDS runs on the NonStop Kernel Guardian
       Personality which includes support for Tandem system characteristics
       such as data integrity, process persistence, and server classes.  NSDS
       supports access over X.25 WAN, LAN and TCP/IP networks.

       NSDS is a port of OSF's DCE GDS Reference Implementation, with Tandem
       enhancements including 1993 X.500 Simplified Access Control. Tandem
       server class management provides fault events, tracing, accounting and
       configuration services for NSDS. TM/MP (Transaction Management) is
       used to protect all file operations that affect the integrity of the
       directory entries in the DIB.

       Major Features Include:

          * X/Open Directory Services (XDS) API and X/Open Object
            Management (XOM) interface in conformance with X/Open CAE
            Specifications, and an additional Tandem extension package

          * 1988 Edition X.500 Conformant DAP and DSP, capable of inter-
            operating with 1993 Edition DUA or DSA implementations

          * Simplified Access Control as specified in the 1993 edition of
            the X.500 standard.

          * Unprotected Simple Authentication (name and password in
            clear)

          * Character set support for T61 Printables, IA5 and Teletex
            Strings

          * The DSA-SC server class performs the functions of a DSA.
            Multiple processes are used for fault tolerance and load
            balancing.

          * The DUA-ACCESS server class handles communications between
            local applications and remote DSA's using DAP across an OSI
            stack.

    Apple & Rossen               Informational                    [Page 121]

    RFC 2116            X.500 Implementations Catalog-96          April 1997

          * The DSA-ACCESS server class handles communications from
            remote DUAs or DSAs to the DSA-SC server class using the
            Tandem OSI stack implementation which includes [RFC 1006]
            support for TCP/IP networks.

          * The DSA-CHAIN server class handles chaining communications
            between the DSA-SC server class and remote DSAs.

          * NSDS GUI Viewer supports administration/management of an NSDS
            DIB on a PC Windows workstation.  The NSDS GUI Viewer is
            supported by a persistent server process on the Tandem
            NonStop Kernel.  The  GUI Viewer allows a directory entry and
            a complete set of attributes and values to be inserted
            anywhere in the directory tree (DIT), to be deleted or
            changed, read or searched based on distinguished name
            components, with or without wild-card.

          * NSDS SCRIPTOR allows customers to explore features of the XDS
            programmatic interface in advance of writing their XOM/XDS
            application. NSDS SCRIPTOR is a menu-driven batch interface
            to XDS functions.

          * A BulkUnload/BulkLoad utility allows a branch of the DIB to
            be dumped to an editable flat file and restored from that
            file.  The flat file can be modified before being bulk-loaded
            into a DIB which may conform to a different schema
            definition.

          * Support for the LDAP protocol.

          * Messaging-Based Directory Query (MDQ) provides a text-based
            query interface to the directory from an X.400 messaging
            system, such as Tandem OSI/MHS, via the XAPIA compliant GPI
            interface.

    COMPLIANCE with X.500-1988  (applicable only for DSAs and DUAs)

       NSDS complies with the '88 CCITT X.500 and ISO 9594 standard, and
       part of '93 X.500 standard.

    NAME

       PMDF-X500

       from:

       Innosoft International, Inc. 1050 East Garvey Ave. South West

    ABSTRACT

       PMDF-X500 is Innosoft's implementation of the X.500 standards for
       Directory Services. PMDF-X500 is based upon the ISODE Consortium
       code-base. The core of PMDF-X500 is the Directory System Agent (DSA)
       server. This server provides directory information to Directory User
       Agents (DUA) using either OSI or TCP/IP networking protocols. Since
       PMDF-X500 is based on a widely used implementation, it interoperates
       particularly well with a whole host of X.500-based products from other
       sources.

       In order to facilitate initial loading of directory data as well as
       ongoing coordination with other directory services, PMDF-X500 includes
       tools to import from and export directory information to Entry
       Description File (EDF) files. EDF files are flat text files.
       PMDF-X500 provides directory coordination functions using EDF files
       for the following directories:

          * X.500 DSAs supporting LDAP access

          * cc:Mail

          * Digital's DDS

          * GroupWise

          * Microsoft Mail

          * PMDF  generic databases

    COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

       OSI directory services as specified in CCITT X.500 Recommendations
       and ISO 9594 use the Directory Access Protocol (DAP) and the
       Directory System Protocol (DSP).

    Apple & Rossen               Informational                    [Page 138]

    RFC 2116            X.500 Implementations Catalog-96          April 1997

    COMPLIANCE with X.500-1993 (applicable only for DSAs and DUAs)

       PMDF-X500 does not yet support the 1993 changes to the X.500
       standard.  Support for the 1993 X.500 recommendations is planned for
       a future release of PMDF-X500.

    CONFORMANCE WITH PROPOSED INTERNET STANDARDS

       PMDF-X500 supports DAP and DSP accesses using Internet protocols as
       specified in [RFC 1006]. In addition, the Internet community has
       proposed two lightweight alternatives to DAP called Lightweight
       Directory Access Protocol (LDAP), which is specified in [RFC 1777],
       and Connectionless Lightweight Directory Access Protocol (CLDAP),
       which is specified in [RFC 1798]. LDAP and CLDAP, which are currently
       specified to run over TCP/IP, are much simpler protocols than DAP and
       were designed to reduce the cost of entry associated with using X.500
       protocols in client applications. PMDF-X500 includes both LDAP and
       CLDAP servers.

       The LDAP server accesses X.500 directory information using DAP to
       communicate with X.500 DSAs. PMDF-X500 provides an LDAP server which
       translates LDAP requests into DAP requests to communicate with X.500
       DSAs. CLDAP defines a very low overhead method for accessing X.500
       directory information. CLDAP is suitable for providing access to
       information that does not require access controls.

    CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL RFCs

       [No information provided. -- Ed.]

    INTEROPERABILITY

       PMDF-X500 interoperates with a large number of DUAs and DSAs. This is
       demonstated by the fact that PMDF-X500 is DSA used by several Internet
       White Pages Project participants. PMDF-X500 DSA interoperability
       includes at least all of the DSA that are used in the White Pages
       Project.

       PMDF-X500 is delivered with several DUAs and in addition is know to
       support the DUAs from Unisys and Digital Equipment Corporation as well
       as the publically available DUAs MaX500, Cello, Swix, and the NASA
       DUA.

    PILOT CONNECTIVITY

       PMDF-X500 is used by several sites that are participants of the
       Internet White Pages Project include the Innosoft DSA.

    CAVEATS AND GENERAL LIMITATIONS

       [No information provided. -- Ed.]

    INTERNETWORKING ENVIRONMENT

       DAP and DSP are layered on top of the OSI protocol suite. PMDF-X500
       supports this protocol suite over multiple network transports. For a
       pure OSI protocol stack, DECnet/OSI can be used to provide the lower
       layers of the stack. In addition, PMDF-X500 supports running OSI upper
       layer protocols over a TCP/IP transport in accordance with [RFC 1006].
       It is important to note that while [RFC 1006] specifies TCP/IP as a
       transport, all of the OSI upper layer protocols are always used with
       DAP and DSP.

    ABSTRACT

       waX.500 :: Windows Access to X.500

       waX.500 is a (currently 16-bit) DUA that run on Microsoft Windows
       (3.1, Win95, & WinNT).  It uses libldap.dll which uses the winsock
       (v1.1) interface.  It works on any vendors tcp/ip stack that I've
       seen so far (some configuration may be required).

       waX.500 was developed by the University of Michigan for use by its
       faculty, staff and students. UM's online directory is an X.500
       directory containing 50,000+ entries.

    NAME

       X500-DS

       X500-DUA

       Bull S.A.

    ABSTRACT

       X500-DS and X500-DUA are integral part of the large Bull OSI offer.
       Although based on the DCE/GDS (Distributed Computing
       Environment/Global Directory Service) of OSF, those two products may
       be installed and used without the DCE environment. Some enhancements
       have been added for the user and the management facilities. X500-DS is
       designed to implement both the DUA and the DSA functions, whilst
       X500-DUA only provides the DUA functions.

       The X500-DUA package contains:

          * The standards APIs XOM (X/Open OSI-Abstract-Data Manipulation
            API) and XDS (X/Open Directory Service API) for the
            development of portable applications,

          * A core DUA to translate all user's requests (bind, read,
            list, compare, modify, modifyRDN, search, add, remove, unbind
            ...) into the DAP protocol used for communication with
            distant DSAs,

          * The OSI standard high layers (ASN.1, ROSE, ACSE, Presentation
            and Session) for communication with the distant DSAs. The
            interface with the low layers is XTI. [RFC 1006] is supported
            under XTI or the OSI Session,

          * A DUA Cache to improve performances when accessing remote
            DSAs,

          * A powerful management application facilitating the
            configuration of the product and controlling the operations,
            logs and traces,

          * A user application for the manipulations of the database
            entries,

          * A generic tool to load and unload ASCII and binary files
            in/from distributed DSAs,

    RFC 2116            X.500 Implementations Catalog-96          April 1997

          * The support of the LDAP [RFC 1777] thanks to an LDAP Server,

          * A DUA Server that allows to use A-Window-To-Directory (refer
            to this DUA product description) on a PC.

       The X500-DS package contains:

          * All components of the X500-DUA,

          * A core DSA to process all requests received from distant DUAs
            through DAP protocol or from distant DSAs through DSP
            protocol,

          * The support of the referral, chained and multi-casting modes
            of operation, access control lists and management of
            knowledge information (for distribution, shadows and  copies
            of sub-trees),

          * The support of the simple authentication and of the DCE
            authentication,

          * A management application for managing the schema information
            (creation, deletion and modification of object classes and of
            attribute types, management of the rules of the DIT).

          * A C-ISAM database that is specially designed for high
            performances: e.g. less than 10 ms to read an entry on an
            Escala at the XOM/XDS interface.

       These two products are easely installed, configured and administered
       thanks to the System Management Interface Tool (SMIT) screens of AIX.

    COMPLIANCE with X.500-1988 (applicable only for DSAs and DUAs)

       Compliant with EWOS and OIW Agreements

       Consists of both DUA and DSA implementation according to the '88
       CCITT X.500 and ISO 9594 standard. The X/Open standard XDS and XOM
       interface libraries are also provided. When the product is installed
       with the DCE environment, XDS and XOM interfaces are also used to
       access DCE/CDS (Local Cell Directory Service) transparently. A GDA
       (Global Directory Agent) serves then as the gateway between the DCE
       CDS and GDS.
