Network Working Group A. 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 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: firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, and email@example.com. 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 (firstname.lastname@example.org) 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 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.

NAME X500-DS X500-DUA Bull S.A. KEYWORDS API, Bull, CLNS, Commercially Available, DSA/DUA, OSI Transport, 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),
- 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. CONFORMANCE WITH PROPOSED INTERNET STANDARDS [No information provided--Ed.] CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL RFCs [No information provided--Ed.] INTEROPERABILITY This implementation of DAP and DSP can interoperate with other X.500 implementations from other Cebit demo participants including IBM, HP, ICL, Siemens-Nixdorf, etc. It also interoperates with ISODE QUIPU.

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
There are no present plans to extend Custos to include the 1992 X.500 extensions. CONFORMANCE WITH PROPOSED INTERNET STANDARDS [No information provided--Ed.] CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL RFCs [No information provided--Ed.] 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, firstname.lastname@example.org. 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 (188.8.131.52) 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. DATE LAST UPDATED or CHECKED March 5th, 1993
NAME DE KEYWORDS Available via FTP, DUA Interface, Free, Included in ISODE, LDAP, Multiple Vendor Platforms, Needs ISODE, RFC-1274, RFC-1484, RFC-1487, Source, UNIX 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 184.108.40.206 and logging in as dua -- no password required. COMPLIANCE (applicable only for DSAs and DUAs) N/A
CONFORMANCE WITH PROPOSED INTERNET STANDARDS [RFC 1274] and [RFC 1487] CONSISTENCE WITH INFORMATIONAL AND EXPERIMENTAL RFCs [RFC 1484]. INTEROPERABILITY N/A PILOT CONNECTIVITY N/A (This is more a DUA rather than an interface question). The interface is widely used in the global pilot. BUGS Doesn't handle aliases well when power searching. Send bug reports to: email@example.com firstname.lastname@example.org 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. It is not possible to display photographs or reproduce sound attributes.

AVAILABILITY The software is openly available as part of ISODE-8.0. An enhanced version is available as part of the PARADISE project upgrade. Both these versions are available by FTP from <ftp.paradise.ulcc.ac.uk>, as src/isode-8.tar.Z and src/isode- paradise.tar.Z. The very latest code will be made available with the ISODE Consortium release of ISODE. It is hoped it will be freely available to all.
