Getchell Request for Comments: 1632 Lawrence Livermore National Laboratory FYI: 11 S. Sataluri Obsoletes: 1292 AT&T Bell Laboratories Category: Informational Editors May 1994 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 RFC1292. We contacted each contributor in RFC1292 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: 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. 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 RFC1292, 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. Source Source code is available, potentially at an additional cost. 2.1.2 Conformance with Proposed Internet Standards These RFCs specify standards track protocols for the Internet community. Implementations which conform to these evolving proposed standards have a higher probability of interoperating with other implementations deployed on the Internet. RFC-1274 Implementation supports RFC1274: Barker, P., and S. Kille, The COSINE and Internet X.500 Schema, University College, London, England, November 1991. RFC-1276 Implementation supports RFC1276: Kille, S., Replication and Distributed Operations extensions to provide an Internet Directory using X.500, University College, London, England, November 1991. RFC-1277 Implementation supports RFC1277: Kille, S., Encoding Network Addresses to support operation over non-OSI lower layers, University College, London, England, November 1991. RFC-1485 Implementation supports RFC1485: Kille, S., A String Representation of Distinguished Names, ISODE Consortium, July 1993. RFC-1487 Implementation supports RFC1487: Yeong, W., T. Howes, and S. Kille, X.500 Lightweight Directory Access Protocol, July 1993. 2.1.3 Consistence with Informational and Experimental Internet RFCs These RFCs provide information to the Internet community and are not Internet standards. Compliance with these RFCs is not necessary for interoperability but may enhance functionality. RFC-1202 Implementation supports RFC1202: Rose, M. T., Directory Assistance Service. February 1991. RFC-1249 Implementation supports RFC1249: Howes, T., M. Smith, and B. Beecher, DIXIE Protocol Specification, University of Michigan, August 1991. RFC-1275 Implementation supports RFC1275: Kille, S., Replication Requirements to provide an Internet Directory using X.500, University College, London, England, November 1991. RFC-1278 Implementation supports RFC1278: Kille, S., A string encoding of Presentation Address, University College, London, England, November 1991. RFC-1279 Implementation supports RFC1279: Kille, S., X.500 and Domains, University College, London, England, November 1991. RFC-1484 Implementation supports RFC1484: Kille, S., Using the OSI Directory to achieve User Friendly Naming, ISODE Consortium, July 1993. 2.1.4 Implementation Type API Implementation comes with an application programmer\'s interface (i.e., a set of libraries and include files). DSA Only Implementation consists of a DSA only. No DUA is included. DSA/DUA Both a DSA and DUA are included in this implementation. DUA Interface Implementation is a DUA-like program that uses either DAP, but supporting only a subset of the DAP functionality, or uses a protocol different from DAP to communicate with a DSA or DUA. DUA Only Implementation consists of a DUA only. No DSA is included. LDAP DUA interface program uses the Lightweight Directory Access Protocol (LDAP). 2.1.5 Internetworking Environment CLNS Implementation operates over the OSI ConnectionLess Network Service (CLNS). OSI Transport Implementation operates over one or more OSI transport protocols. RFC-1006 Implementation operates over RFC-1006 with TCP/IP transport service. RFC-1006 is an Internet Standard. X.25 Implementation operates over OSI X.25. 2.1.6 Pilot Connectivity DUA Connectivity The DUA can be connected to the pilot, and information on any pilot entry looked up. The DUA is able to display standard attributes and object classes and those defined in the COSINE and Internet Schema. DSA Connectivity The DSA is connected to the DIT, and information in this DSA is accessible from any pilot DUA. 2.1.7 Miscellaneous Included in ISODE DUAs that are part of ISODE. Limited Functionality Survey states that the implementation has some shortcomings or intended lack of functionality, e.g., omissions were part of the design to provide an easy-to-use user interface. Motif Implementation provides a Motif-style X Window user interface. Needs ISODE ISODE is required to compile and/or use this implementation. OpenLook Implementation provides an OpenLook-style X Window user interface. X Window System Implementation uses the X Window System to provide its user interface. 2.1.8 Operating Environment 386 Implementation runs on a 386-based platform. Bull Implementation runs on a Bull platform. CDC Implementation runs on a CDC MIPS platform. DEC ULTRIX Implementation runs under DEC ULTRIX. DEC Vax OpenVMS Implementation runs on a DEC VAX platform running OpenVMS. HP Implementation runs on an HP platform. IBM PC Implementation runs on a PC.

Wang Implementation runs on a Wang RISC platform. 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). 386 CLNS
