          A Revised Catalog of Available X.500 Implementations

Status of this Memo

   This memo provides information for the Internet community.  This memo
   does not specify an Internet standard of any kind.  Distribution of
   this memo is unlimited.


   This document is the result of a survey that gathered new or updated
   descriptions of currently available implementations of X.500,
   including commercial products and openly available offerings. This
   document is a revision of RFC 1292. We contacted each contributor in
   RFC 1292 and requested an update and published the survey template in
   several mailing lists and obtained new product descriptions.

   This document contains detailed description of twenty six (26) X.500
   implementations - DSAs, DUAs, and DUA interfaces.

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,

        A DSA is an OSI application process that provides the Directory

        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 surveying several Internet mailing lists,
   including:  iso@nic.ddn.mil, isode@nic.ddn.mil, osi-ds@cs.ucl.ac.uk,
   and ietf-ids@umich.edu. We also contacted many people by telephone
   and sent the template to several individuals and mailed a floppy disk
   containing the survey template to a person who did not have Internet

   Readers are encouraged to submit comments regarding both the form 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 editors.  IDS will produce new ver-
   sions of this document when a sufficient number of changes have  been
   received.  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 can not guarantee the accuracy
   or completeness of the descriptions, or the stability of the

1.4  Overview

   Section 1 contains introductory information.

   Section 2 contains a list of keywords, their definitions, and a cross
   reference of the X.500 implementations by these keywords.

   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 1292, Ruth Lang and
   Russ Wright who helped us get started and made key suggestions that
   enabled us to learn from their experience. We also acknowledge and
   appreciate the efforts of Ken Rossen in obtaining six descriptions.

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
