Abstract

   This document is a draft of 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.

   This document contains detailed description of TBD X.500
   implementations - DSAs, DUAs, and DUA interfaces.

INTERNET-DRAFT      X.500 Implementations Catalog-96        3 March 1996


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
   (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

   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.

              Table 2-1: Table of Implementation Identifiers

   The index is organized as follows: keywords appear in alphabetical
   order; implementations characterized by that keyword are listed
   alphabetically as well.  Note that a "*" is used to indicate that the
   particular implementation, or feature of the implementation, may not
   be available at this time.

   For formatting purposes, we have used the abbreviations for
   implementation names as defined above in Table 2-1.

INTERNET-DRAFT                  DC X500                     3 March 1996


NAME

   DC X500

   Data Connection Ltd
   100 Church Street

   UK

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:

INTERNET-DRAFT                  DC X500                     3 March 1996


         - genuine multi-threaded implementation

         - 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

   Digital X.500 Directory Server
   Digital Equipment Corporation

   This single entry covers a number of different products

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 RFC1006)
           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.

INTERNET-DRAFT       Digital X.500 Directory Server         3 March 1996


         * 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.

         * An award winning documentation set.

   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
   edition DUAs and DSAs, and are implemented to conform to relevant

INTERNET-DRAFT  ISODE Consortium Release 3.0 X.500(1993)    3 March 1996


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.

INTERNET-DRAFT  ISODE Consortium Release 3.0 X.500(1993)    3 March 1996


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

INTERNET-DRAFT                    LDAP                      3 March 1996


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

INTERNET-DRAFT                    LDAP                      3 March 1996


   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: "The COSINE and Internet X.500 Schema"
      RFC-1777: "Lightweight Directory Access Protocol"
      RFC-1778: "The String Representation of Standard Attribute
      Syntaxes"
      RFC-1779: "A String Representation of Distinguished Names"
      RFC-1781: "Using the OSI Directory to Achieve User Friendly
      Naming"

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: "A String

   Representation of LDAP Search Filters."

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 ruuning 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.

INTERNET-DRAFT                  maX.500                     3 March 1996


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:








Apple, Rossen                                                  [Page 78]


INTERNET-DRAFT                  maX.500                     3 March 1996



             RFC-1274: "The COSINE and Internet X.500 Schema"
             RFC-1777: "Lightweight Directory Access Protocol"
             RFC-1778: "The String Representation of Standard Attribute Syntaxes"
             RFC-1779: "A String Representation of Distinguished Names"
             RFC-1781: "Using the OSI Directory to Achieve User Friendly Naming"


CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL RFCs

   Search filters comply with RFC-1558: "A String Representation of LDAP
   Search Filters."  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.

INTERNET-DRAFT                  maX.500                     3 March 1996


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.

   Phone:  +1 818-919-3600 email: sales@innosoft.com

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

   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 RFC1777, and
   Connectionless Lightweight Directory Access Protocol (CLDAP), which
   is specified in RFC1798.  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.

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
   RFC1006. It is important to note that while RFC1006 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.

   I keep the following Web page up to date with respect to latest

INTERNET-DRAFT            X.500-DS, X.500-DUA               3 March 1996


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 (Open Software
   Foundation), these 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 of the stack being 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.




Apple, Rossen                                                  [Page 97]


INTERNET-DRAFT            X.500-DS, X.500-DUA               3 March 1996


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

         * A DUA Server that allows to use "A-Window-to-Directory"
           (refer to this 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 the DAP protocol or from distant DSAs through the DSP
           protocol. It supports the referral, chained and multi-casting
           modes of operation, access control lists, simple
           authentication, management of knowledge information (for
           distribution, shadows and copies of sub-trees).

         * 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. 6 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.

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.

   It is planned to support '93 extensions in the products for 1996.
