	  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.

Abstract

   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,

   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.

RFC 1632		     X.500 Catalog			May 1994


   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:  [e-mail],	[e-mail], [e-mail],
   and [e-mail]. 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
   access.

   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
   ([e-mail])	 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
   implementations.

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.

RFC 1632		     X.500 Catalog			May 1994


   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
   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.

   Commercially	Available
	This implementation can	be purchased.

   Free
	Available at no	charge,	although other restrictions may	apply.

   Limited Availability
	Need to	contact	provider for terms and conditions of
	distribution.

   standards have a higher probability of interoperating with other
   implementations deployed on the Internet.

   Internet standards. Compliance with these RFCs is not necessary for
   interoperability but	may enhance functionality.

   RFC-1202
	Implementation supports	RFC 1202: Rose,	M. T., Directory

   DSA/DUA
	Both a DSA and DUA are included	in this	implementation.

   DUA Interface

2.2  Implementations Indexed by	Keyword

   This	section	contains an index of implementations by	keyword.  You
   can use this	list to	identify particular implementations that meet
   your	chosen criteria.

   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 following abbreviations for
   implementation names: BULL S.A. (Bull X500-DS and X500-DUA),	DEC
   X.500 DSA (DEC X.500	Directory Server), DEC X.500 Admin (DEC	X.500
   Administration Facility), HP	X.500 DD (HP X.500 Distributed
   Directory), LDAP (University	of Michigan LDAP Implementation), OSI
   Access & Dir	(OSI Access and	Directory), and	Traxis (Traxis
   Enterprise Directory).
