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.

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: [email protected], [email protected], [email protected], and [email protected]. 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 ([email protected]) or to the editors. IDS will produce new versions 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.

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.

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 X500-DS package contains:

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
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:

There are no present plans to extend Custos to include the 1992 X.500 extensions.

INTEROPERABILITY

Have successfully interoperated with QUIPU and OSIWARE over the DAP. No DSP interoperability testing has been done.

PILOT CONNECTIVITY

Limited DUA and DSA connectivity to PSI White Pages Project.

BUGS

Bugs may be reported to the general discussion list, [email protected].

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.

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.

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.

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 DAP and DSP protocols.

Data Shadowing and security access control of HP X.500 Distributed 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:

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.

CONFORMANCE WITH PROPOSED INTERNET STANDARDS

Compliant with [RFC 1485], [RFC 1487], and [RFC 1274].

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 [email protected].

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.

AVAILABILITY

This software is openly available. It may be obtained by anonymous FTP from terminator.rs.itd.umich.edu in the x500 directory. Documentation on the LDAP and lightweight BER libraries is provided in the form of man pages distributed with the source code. More information can be obtained from [email protected].

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.

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 [email protected].

CAVEATS and GENERAL LIMITATIONS

None.

INTERNETWORKING ENVIRONMENT

Traxis Directory Hub to Traxis Directory Engine (or any DSA) communication via RFC1006 over TCP/IP, OSI TP4 with CLNS, and OSI TP0 with X.25. Traxis Desktop Client to Traxis Directory Hub via SPX/IPX or TCP/IP. Other LAN protocols supported in 1994.

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

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.

HARDWARE PLATFORMS

ABSTRACT
Wang's X.500 products are a part of our OPEN/services product whose main features include the following:

X.500 directory - Contains information about organizations, individuals, and distribution lists. The directory is the primary vehicle by which users of OPEN/office, Wang's X.400 electronic mail product, address mail.

Authentication Services - Verifies the login name and password of each user logging into OPEN/services.

International support - Provides character translation tables so that users can display screens containing international characters and use international collating sequences.

Object management - Greatly increases the integration between OPEN/services, OPEN/office and other Windows-based applications.

Activity logging - Records the activities of OPEN/services. This information can be useful for monitoring the OPEN/services processes and for troubleshooting.

Database management - Provides utilities that validate and reorganize the OPEN/services databases including the Directory Information Base (DIB).

OPEN/services includes a DSA, a DUA, and a DUA interface all rolled into one product. (The DUA interface protocol is private.)

Wang OPEN/services consists of two parts: software installed on a server and software installed on PC clients on a LAN. The client or end-user software enables users to log in and log out; change the login password; use the OPEN/services directory; and perform various actions, such as open and print, on files in the Wang OPEN/applications and in certain third-party applications including Microsoft Windows File Manager. The server consists of the DSA, the DUA, the Directory Information Base, the service administration programs such as login authentication, the database management utilities, and activity logging.

COMPLIANCE (applicable only for DSAs and DUAs)

Wang OPEN/services complies with the 1988 CCITT Recommendations X.500-X.521 [CCITT-88] with the following exceptions. Whole tree searches are not supported, nor does the product support chained adding, modifying, or deleting. Simple authentication is supported, but strong authentication is not.

In the future, the 1992 extensions to the X.500 standard will be supported by Wang OPEN/services.

CONFORMANCE WITH PROPOSED INTERNET STANDARDS

None are supported at the present time.

KEYWORDS
Available via FTP, DUA Connectivity, DUA Only, Free, Limited Functionality, Multiple Vendor Platforms, Needs ISODE, RFC-1274, RFC-1484, Source, Sun, UNIX, X Window System

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.

CONFORMANCE WITH PROPOSED INTERNET STANDARDS

RFC 1274 is supported.
