          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.

Top       Page 2 
   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.

Top       Page 3 
   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.

   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

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),

Top       Page 18 
   - 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.

ABSTRACT

   OSI Access and Directory includes several DUAs and a QUIPU based DSA
   (originally based on version 6.6) with enhancements. The DUA/DSA
   enhancements include:

   - Directory API based on the X.400 API.
   - Support for X.400 objects including those to support
     MHS use of Directory to support MHS Routing.
   - Integration with Control Data's MailHub (X.400 MHS) products.

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

INTEROPERABILITY

   Have successfully interoperated with QUIPU and OSIWARE over the DAP.

   Limited DUA and DSA connectivity to PSI White Pages Project.

BUGS

   Bugs may be reported to the general discussion list,
   x500@osi.ncsl.nist.gov.

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.

Top       Page 25 
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.

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.
