	  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:  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
   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
   (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
   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

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:

   NAME
	The name of the	X.500 implementation and the name of the
	responsible organization.  Implementations with	a registered
	trademark indicate this	by appending "(tm)", e.g., GeeWhiz(tm).

   KEYWORDS
	A list of the keywords defined in Section 2 that have been used
	to cross reference this	implementation.

   ABSTRACT
	A brief	description of the application.	 This section may
	optionally contain a list of the pilot projects	in which the
	application is being used.

   COMPLIANCE (applicable only for DSAs	and DUAs)
	A statement of compliance with respect to the 1988 CCITT
	Recommendations	X.500-X.521 [CCITT-88],	specifically Section 9
	of X.519, or the 1988 NIST OIW Stable Implementation Agreements
	[NIST-88].

   RFC-1006, X.25

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, these two products may
   be installed	and used without DCE environment.  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 protocols	(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 Session,
   - A DUA Cache to improve performances when accessing	remote DSAs,
   - A management application for configuration	of the product,
     controlling the operations	and managing logs and traces,
   - A user application	for the	manipulations of the database entries.


   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.
     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),



RFC 1632		     X.500 Catalog		       Bull S.A.


   - 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.


COMPLIANCE (applicable only for	DSAs and DUAs)

   Compliant with EWOS and OIW Agreements

   Strong authentication in X.509 is not yet implemented. (Password
   scheme is currently used.)

   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 full 1992 extensions in the	products for
   1995.

NAME

   Custos
   National Institute of Standards and Technology


KEYWORDS

   API,	Available via FTP, DSA/DUA, Free, Limited Functionality,
   Multiple Vendor Platforms, Needs ISODE, OSI Transport, RFC-1006, Sun,
   UNIX

ABSTRACT

   The implementation consists of a set	DUA library routines, a	terminal
   interface, and a DSA. The implementation was	developed in C on Sun
   SPARCstations under SunOS 4.1.1. All	underlying services are	provided
   by the ISODE	development package. The development package is	also
   used	for encoding and decoding ASN.1	data as	well as	for other data
   manipulation	services. Using	the ISODE package the implementation can
   be run over both TCP/IP and OSI protocols.

   The DSA provides full support for both DAP and DSP protocols,
   conformant with ISO 9594 / CCITT X.500 standards. The DIB is
   maintained using a locally developed	relational database system. The
   interface to	the database system consists of	a set of sql-like C
   functions.  These are designed to allow straightforward replacement
   of the local	database system	with a more powerful commercial	system.
   To achieve better performance several options are supported that
   permit loading of selected portions of the database in core.	When
   these options are selected data can be retrieved more quickly from in
   core	tables;	all modifications to the DIB are directly reflected in
   the in core tables and the database.

COMPLIANCE (applicable only for	DSAs and DUAs)

   Custos is fully compliant with the 1988 Standard with the following
   omissions:

   - Search request decomposition
   - Modify Entry operation
   - Modify RDN	operation
   - Abandon operation
   - Strong Authentication
   - Schema checking

CAVEATS	and GENERAL LIMITATIONS

   No limitations on file sizes, etc. The only side effects to creating
   large files should be in the	area of	performance. Specifically,
   optimization	requires loading parts of the DIB in core so greater
   memory requirements will be necessary for achieving better
   performance with a large database. Any platform the implementation
   can be ported to (generally any platform ISODE can be ported	to)
   should support all features.

INTERNETWORKING	ENVIRONMENT

   RFC-1006; TP4/CLNP (SunLinkOSI) over	802 and	X.25 (SunLink X.25).

HARDWARE PLATFORMS

   It's	only been run on Sun 3 and SPARC, but there are	no known reasons
   why it shouldn't run	on any hardware	running	the ISODE software.








RFC 1632		     X.500 Catalog			  Custos


SOFTWARE PLATFORMS

   It requires UNIX and	the ISODE software package. It's been developed
   and tested with ISODE version 7.0 and Sun OS	version	4.1.1. Uses a
   locally developed relational	DBMS that should be easily replaceable
   with	commercially available relational systems.

AVAILABILITY

   Custos, the NIST implementation of X.500, the OSI Directory,	is
   available for anonymous ftp from osi.ncsl.nist.gov (129.6.48.100)
   using the convention	(user name = anonymous,	password = ident). The
   software is available in two	forms: a tar file and a	compressed tar
   file.

      ./pub/directory/CustosRel_0.2.tar
      ./pub/directory/CustosRel_0.2.tar.Z

   Note: permissions on	the directory ./pub/directory are set so that
   you will be able to "get" files whose names you can provide.	However,
   you will not	be able	to "ls"	the contents of	the directory.

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.

   A lot of development	has been done on the interface since it	was
   first described in RFC1292.	The most significant enhancement has
   been	to add power searching - 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
   now provides	UFN style searching.  It is now	possible to search
   locality entries.  DE now 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.	 An experimental feature is intended to	give the
   user	more feedback on the likely response time to a query - DE
   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
   128.86.8.56 and logging in as dua --	no password required.

NAME

   Directory 500 (tm)

KEYWORDS

   Commercially	Available, DS/DUA, RFC-1006, Source, Sun, X.25

ABSTRACT

   Directory 500 (D500)	is a comprehensive implementation of the CCITT
   X.500 recommendations. D500 is comprised of two major components
   which are responsible for manipulating the data in the OSI Directory.
   They	are the	Directory User Agent (DUA) and the Directory System
   Agent (DSA).

   The DUA is the interface between the	OSI Directory and those	users
   wishing access to the Directory's information. Users	make their
   requests through the	DUA. When forwarding user's requests to	the OSI
   Directory, the protocol used	is known as the	Directory Access
   Protocol (DAP).

   The DSA will	negotiate with other, remote DSAs to obtain requested
   information or to update remote DIBs. DSAs use the Directory	System
   Protocol (DSP) to forward and answer	these requests.	The DSA	supports
   chaining and	referrals.

COMPLIANCE (applicable only for	DSAs and DUAs)

   All X.500 1988 operations are supported along with all Object Classes
   specified in	X.521 and all Attribute	Types specified	in X.520.

   Implementation plans	include	upgrades to support the	1992 extensions
   to X.500 in 1994. Please check with OSIware / Infonet Software
   Solutions for availability dates.

KEYWORDS

   Available via FTP, DUA Interface, Free, IBM PC, LDAP, Multiple Vendor
   Platforms, RFC-1274,	RFC-1484, RFC-1487

ABSTRACT

   DOS-DE (DOS Directory Enquiries) is intended	to be a	simple-to-use
   DUA interface suitable for the naive	user.  It is an	MS-DOS port of
   the standard	UNIX DE	implementation - see the entry on DE for full
   details.  (All of the features DE are supported apart from the
   experimental	`Quality of Service' code).

   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.  `Power searching' is
   also	available - 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.  DOS-DE provides UFN
   style searching.  It	is also	possible to search locality entries.
   DOS-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.

   DOS-DE runs over the	University of Michigan LDAP.

   DE was funded by the	COSINE PARADISE	project.  DOS-DE was developed
   by Andy Powell at the University of Bath.

       X.500 Address Look-up,
       X/Open Application Tool Kit API (XAT) for XDS/XOM Interface,
       X.500 High Level	API (X5HLAPI) for XDS/XOM Interface.

   HP X.500 Distributed	Directory is based on the 1988 CCITT X.500
   standard.  HP X.500 can be used for accessing names and electronic
   mail	addresses for multi-vendor messaging backbone networks.	HP X.500
   can also be used for	the development	of networked applications
   requiring distributed directory functionality.

   HP OpenMail users can access	the enterprise wide HP X.500 distributed
   directory directly from the HP OpenMail user	interface, and select
   X.500 addresses for mailing.	HP-UX Sendmail users can access
   electronic mail addresses from a X.500 server over a	TCP/IP network.

   Users of non-HP e-mail systems can access data stored in the	X.500
   Directory using X.500 Address Look-up. X.500	Address	Look-up	has an
   easy	to use interface, and phonetic search capability.

   HP X.500 Distributed	Directory includes a complete multi-threaded DUA
   and DSA. The	X.500 DIB is built on a	database which has been
   optimized for X.500 performance. HP X.500 contains full support for

   Directory allow higher performance, and easier management of	its DIB
   database in a global	environment.

   HP X.500 Distributed	Directory has menu driven administration and
   user	interface tools. The tools simplify directory configuration and
   data	retrieval. It supports X/Open X.500 APIs (XDS and XOM),	and high
   level APIs on top of	XDS to allow developers	to write their own X.500
   based applications.

   HP X.500 Distributed	Directory supports comprehensive tracing and
   logging facilities for quick	diagnosis and resolution of problems. HP
   also	provides a rich	set of troubleshooting tools to	check the
   interoperability of the network at various layers of	the OSI	stack.

ABSTRACT

   LDAP	is the Lightweight Directory Access Protocol.  It gives	X.500
   access to platforms that have only TCP/IP access, using simplified
   BER encoding	of many	X.500 data elements.  LDAP is currently	a
   proposed Internet Standard.	The LDAP server	is an intermediate
   protocol server that	communicates with Internet clients on one side
   using the simple TCP-based LDAP protocol and	an X.500 DSA on	the
   other side using the	Directory Access Protocol (DAP).  A subset of
   the X.500 DAP is exported to	the clients through the	LDAP protocol.

   The U-M LDAP	distribution contains the following components:

   - LDAP server
   - LDAP client library, including both synchronous and asynchronous APIs
   - Lightweight BER library, including	an API that supports
     a printf/scanf-like interface
   - Various LDAP client programs, including a finger daemon (xfingerd),
     gopher to X.500 gateway (go500gw),	command-line DUA (ud), e-mail
     query server (rcpt500), and an X.500 mailer (mail500)


COMPLIANCE (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.

CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL	RFCs

   Preliminary support is included for [RFC 1484].

INTEROPERABILITY

   The current implementation of the LDAP server is known to work with
   the QUIPU DSA and DAP library.

PILOT CONNECTIVITY

   DUA connectivity should be possible to all pilots, though only
   AARNET, PARADISE, and PSI White Pages Project have actually been
   tried.

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 LDAP server is known to run on Sun 3 and	Sun 4 platforms	DEC's,
   HP's, and RS	6000's.	 The LDAP client libraries and some clients have
   been	ported to the Macintosh	and the	PC.

SOFTWARE PLATFORMS

   The LDAP server and clients are known to run	under and SunOS	4.1.x,
   ULTRIX, HP-UX, and AIX.  The	LDAP client libraries also work	under
   Macintosh System 6.0	or higher and MS-DOS 5.0.

   Source, Sun,	UNIX, X.25

ABSTRACT

   This	implementation is a source release derived from	the earlier
   openly available version of QUIPU, and will be used as base
   technology for products by a	number of vendors. The release comprises
   of a	DSA, and a number of sample DUAs which may be used in
   conjunction with the	DSA.

COMPLIANCE (applicable only for	DSAs and DUAs)

   The DSA is aligned to the 1988 ISO IS and the NIST OIW Directory
   Implementors	Guide Version 1, with the following exceptions:

   - Strong authentication is not implemented (but hooks are
     provided for use with two packages).
   - QUIPU does	not enforce the	bounds constraints on attributes,
     filters or	APDU size.
   - T.61 string formatting characters are not rejected.
   - If	a DN is	supplied with no password in an	unprotected simple bind,
     QUIPU does	not always check to see	if the DN exists. If the DSA
     connected to can say authoritatively the DN does not exist, the
     association is rejected. However, if a chain operation is required
     to	check the DN, the bind IS allowed.
   - When comparing attributes of UTCtime syntax, if the seconds field
     is	omitted, QUIPU does not	perform	the match correctly (i.e., the
     seconds field in the attribute values should be ignored, but are
     not).
   - QUIPU always supplies the optional	Chaining argument
     "originator" even if the CommonArgument "requestor" is used.
   - QUIPU always supplies the optional	Chaining argument "target"
     even if the base object in	the DAP	arguments is the same.
   - The object	class "without an assigned object identifier" is
     not recognised unless the "alias" object class is also present.
   - Non Specific Subordinate References are never followed by a QUIPU
     DSA, but they are passed on correctly to the client if generated.



RFC 1632		     X.500 Catalog  QUIPU (ISODE Con. Rel. 1.0)


   Compliance with X.500(1993) standards is planned. DAP and replication

INTEROPERABILITY

   Interoperability with several other DSAs has	been demonstrated in
   pilot operation and at the COS X.500	Interoperability Lab, enhancing
   interoperability results from the earler versions of	QUIPU.

PILOT CONNECTIVITY

RFC 1632		     X.500 Catalog   Traxis Enterprise Directory


NAME

   Traxis Enterprise Directory
   Angeli Systems Corporation


KEYWORDS

   API,	CLNS, Commercially Available, DSA/DUA, HP, IBM PC, IBM RISC,
   Macintosh, OSI Transport, RFC-1006, RFC-1274, Sun, X.25

ABSTRACT

   The Traxis Enterprise Directory has multiple	components in a	three
   layer architecture. The individual components of the	Traxis family
   are building	blocks which can be assembled in a flexible, modular way
   to build complex systems.

   At the enterprise level, is a distributed directory stored and
   managed by Traxis Directory Engines (TDEs). At the workgroup	level
   Traxis Directory Hubs (TDHs)	provide	the means to integrate and
   connect Traxis Directory Engines to the wide	variety	of real	world
   applications	and systems which prevail in network environments. The
   TDE and the TDH support the myriad of client	applications, including
   messaging and business applications,	which require services from the
   Traxis directory.

   At the desktop level, the Traxis Desktop Client (TDC) provides a
   common set of facilities which simplify and enable communications,
   object manipulation,	and results management as required between the
   Traxis Directory Hub	and applications. These	capabilities, which
   include full	access and management of the directory,	are provided to
   applications	through	XDS++, the Traxis object oriented API. The
   Traxis Desktop Client also supports industry	standard client	software
   interfaces such as Microsoft	MAPI, Apple OCE, CMC and VIM, through
   Compatibility Modules which map the standard	API into XDS++.	Through
   these APIs the Traxis Desktop Client	supports applications of all
   kinds on PC,	Macintosh, and UNIX systems.

   Angeli supplied Traxis applications include the Traxis Administrative
   Console management station, the Traxis Global Browser general
   directory tool, the Traxis Operator Assistance high-speed look-up,
   the Traxis Data Base	Gateway, the Traxis Import Export Utility and
   more.

   The Traxis Directory	Engine includes	an X.500 DSA. The Traxis
   Directory Hub includes an X.500 DUA.




RFC 1632		     X.500 Catalog   Traxis Enterprise Directory


COMPLIANCE (applicable only for	DSAs and DUAs)

   Traxis Directory Engine DSA is CCITT-1988 compliant with extended
   security and	access control.	Supports access	control	on User, Entry,
   and Attribute levels. DIB or	subtree	administrative manager
   supported. Supports simple authentication with encrypted password.

   NIST	OIW Stable Implementation Agreements [NIST-88] compliant.

   Support for February	14, 1993 CCITT X.500 planned. X.509 in first
   half	of 1994. Replication and Administrative/Information Model in
   second half of 1994.

CONFORMANCE WITH PROPOSED INTERNET STANDARDS

   Traxis conforms to RFC1274 which documents COSINE interoperability.

   LDAP	(RFC 1487) is planned for inclusion in a later release of Traxis
   if market demand requires it.

CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL	RFCs

   Traxis does not conform to the QUIPU	RFC Internet Proposals cited.
   As noted elsewhere, Traxis is fully compatible with QUIPU
   operationally but does not use the cited RFCs in its	internal
   operations.

INTEROPERABILITY

   Traxis has been extensively tested for interoperability with	ISODE
   QUIPU Version 8. Traxis Directory Engine (DSA) will serve DISH or
   other QUIPU DUAs using DAP. Traxis Directory	Hub interoperates with
   QUIPU DSA. All directory access functions and their chained
   equivalents are interoperable.

PILOT CONNECTIVITY

   PARADISE DUA/DSA connectivity tested.

BUGS

   Problems may	be reported to support@angeli.com.

RFC 1632		     X.500 Catalog		      UCOM.X 500


NAME

   UCOM.X 500 (tm) - E3.X [DSA and DUA]


KEYWORDS

   386,	API, Bull, CLNS, Commercially Available, DEC ULTRIX, DSA
   Connectivity, DSA/DUA, DUA Connectivity, IBM	RISC, Motif, Multiple
   Vendor Platforms, OpenLook, RFC-1006, RFC-1274, RFC-1277, RFC-1278,
   RFC-1279, Sequent, Sun, Tandem, UNIX, X.25

ABSTRACT

   UCOM.X 500 includes a Directory System Agent	(DSA), various directory
   access APIs and Directory User Agents (DUAs). UCOM.X	500 is a product
   based on PIZARRO, the research prototype developed at INRIA by
   Christian Huitema's team, and commercialized	by TS-E3X, 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.
   - 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
     UCOM.X specific attributes	of the DSA entries.
   - 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 are being tested	operationally through TS-E3X's
     participation in PASSWORD,	a VALUE	project	with aim to pilot a
     European security infrastructure for network applications.
   - Access control: private mechanisms	are provided to	allow access
     control lists to be specified for parts of	the DIT, to control
     modifications, and	to specify access restrictions on attributes.
   - Management: a UCOM.X DSA object has been defined to allow
     operational parameters of the DSA to be managed via DAP.
     Administration utilities are provided to, e.g., generate usage
     statistics	and periodically update	the database from various data
     sources including a knowledge discovery tool.


   The product offers a	C language API conformant to X/Open's X/DS



RFC 1632		     X.500 Catalog		      UCOM.X 500


   specification, and a	C++ API	(for release 10/93).

   The DUAs include a graphical	directory browser with powerful	search
   functionality for OpenLook and Motif, and a full-screen curses-based
   interface with full DAP functionality.

   TS-E3X's strategy for UCOM.X500 is three-fold: Firstly, to use it as
   the directory service for Spheris, France Telecom's range of
   electronic mail products based on X.400 (88)	(release mid '94).
   Secondly, to	offer it to third parties developing specific
   applications	using X.500: current applications include a distributed
   application to control document transfer in a large French hospital
   and distributed applications	management in the French Post Office;
   planned uses	include	office applications for	control	of document
   circulation (workflow) and cooperative document editing. Thirdly, to
   offer it to telecomms operators such	as France Telecom for
   application in network management. UCOM.X 500 is used extensively by
   French research centers involved in PARADISE.

COMPLIANCE (applicable only for	DSAs and DUAs)

   UCOM.X 500 conforms to X.500	(88) as	specified in paragraph 9 of
   X.519.

   Development of the product based on X.500 (93) is planned for '94
   with	release	of a product conformant	to the principal extensions at
   the end of '94. Emphasis is being placed on the shadowing protocol,
   the schema and access control.

CONFORMANCE WITH PROPOSED INTERNET STANDARDS

   The COSINE and Internet Schema (RFC 1274) is	supported with minor
   exceptions.

   The string representation of	PSAPs and their	internal encoding
   conforms to RFC 1277.

   The string representation of	DNs will migrate to the	Internet RFC
   1485	definition.

CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL	RFCs

   RFC 1279 (X.500 and Domains)	is supported. The string representation
   of PSAPs and	their internal encoding	conforms to RFC	1278.

   AFRO	(algorithme francais de	recherche optimise), the search	/ name
   resolution algorithm	proposed by UCOM.X 500,	differs	from the UFN
   algorithm principally in that it attempts to	optimize by performing



RFC 1632		     X.500 Catalog		      UCOM.X 500


   read	operations before resorting to searches	in order to exploit the
   name	error information.

INTEROPERABILITY

   Through UCOM.X 500's	use in the French PARADISE pilot,
   interoperability has	been informally	but extensively	tested with
   Quipu and other implementations.

   Detailed interoperability tests  with Quipu,	Marben and  Siemens/Bull
   DIR/X are being conducted by	 the PARADISE OIFP (Operational
   Interworking) team at INRIA Rocquencourt, France.

   The product	is currently also undergoing  formal tests for
   conformance to the CTS2  DSA/DAP and	 ACSE/Presentation/Session
   specifications  at the  French OSI conformance test centre.


PILOT CONNECTIVITY

   DSA and DUA connectivity to the PARADISE pilot.

BUGS

   UCOM.X 500 is a commercial product. As such,	it is supported	and bugs
   are fixed when detected. Bug	reports	can be sent to our support team
   via electronic mail.

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 1 kb per node,
   i.e., 10 Mb for a database of 10,000	objects. The current recommended
   maximum is a	database size of the order of 100,000 objects.

   Of the selected attribute types defined in X.500 (88), the
   searchGuide attribute is not	supported ; neither are	the following
   attributes from the Cosine and Internet Schema (RFC 1274):
   OtherMailbox, MailPreferenceOption and the various quality
   attributes.

   The X/DS API	supports the Basic Directory Contents (BDCP), the MHS
   Directory User (MDUP) and the Strong	Authentication (SAP) packages
   with	minor limitations. A proprietary mechanism for defining	new
   classes and attributes is offered. Asynchronous operations and
   multiple concurrent sessions	are not	supported. Whilst referral may
   be handled automatically, continuation references are not.




RFC 1632		     X.500 Catalog		      UCOM.X 500


INTERNETWORKING	ENVIRONMENT

   UCOM.X 500 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.

ABSTRACT

   Xdi is a Directory User Agent (DUA) for the X Window	System.	 In
   addition to providing a user-friendly interface, it supports
   Directory interactions of different levels of complexity. Users can
   select different window screens to browse, search and modify	the
   Directory.  There are two different search screens for name based
   search and attribute	based search. It is simple to use for novice
   users but is	also useful for	more advanced users to formulate complex
   search filters.  Xdi	also supports "user-friendly naming" in	many
   cases so that users are not required	to know	X.500 naming format.


COMPLIANCE (applicable only for	DSAs and DUAs)

   88 standard compliant: Delete and Add operations, and strong
   authentication not implemented. There are no	facilities to modify the
   RDNs	of entries.
