Network Working Group R. Lang Request for Comments: 1292 SRI International FYI: 11 R. Wright Lawrence Berkeley Laboratory Editors January 1992 A Catalog of Available X.500 Implementations Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited. Abstract The goal of this document is to provide information regarding the availability and capability of implementations of X.500. Comments and critiques of this document, and new or updated descriptions of X.500 implementations are welcome. Send them to the Directory Information Services Infrastructure (DISI) Working Group (firstname.lastname@example.org) or to the editors. 1. Introduction This document catalogs currently available implementations of X.500, including commercial products and openly available offerings. It contains descriptions of Directory System Agents (DSA), Directory User Agents (DUA), and DUA client applications. The latter can include such applications as browsers, DSA management tools, or lightweight DUAs that employ an application-level protocol to communicate with a DUA (which then in turn communicates with a DSA) to support user service. Section 2 of this document contains a listing of implementations cross referenced by keyword. This list will aid in identifying particular implementations that meet your criteria. To compile this catalog, the DISI Working Group solicited input from the X.500 community by surveying several Internet mailing lists, including: email@example.com, firstname.lastname@example.org, email@example.com, and firstname.lastname@example.org.
Readers are encouraged to submit comments regarding both the form and content of this memo. New submissions are always welcome. Please direct input to the parties as described in the Status of this Memo section. DISI will produce new versions of this document when a suf- ficient number of changes have been received. This will be deter- mined subjectively by the DISI chairperson. 1.1 Purpose The growth of existing X.500 pilot activities (e.g., White Pages Pilot Project) and the advent of new pilots (e.g., ARRNet Directory Services Project, NIST/GSA Pilot Project) are signals that X.500 is a viable directory service mechanism for the Internet community. A goal of DISI is to enable the continued growth of X.500 by lowering the lack-of-information barrier. This document takes one step toward that goal by providing an easily accessible source of information on X.500 implementations. 1.2 Scope This document contains descriptions of either commercially or freely available X.500 implementations. It does not provide instructions on how to install, run, or manage these implementations. Because the needs and computing environments of each organization differ vastly, no recommendations are given. The descriptions and indices are provided to make the readers aware of existing options and to enable more informed choices. 1.3 Disclaimer Implementation descriptions were written by implementors and vendors, and not by the members of DISI. Although DISI has worked with the description authors to ensure readability, no guarantees can be made regarding the validity of descriptions or the value of said implementations. Caveat emptor. 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 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 DISI Working Group. The editors thank you for your hard work and constructive feedback. A special thanks is also extended to the members of the NOCTools Working Group. The "Network Management Tool Catalog" (RFC-1147) served as a valuable example. Bob Stine and Bob Enger made key suggestions that enabled us to learn from their experiences. The efforts of the editors were sponsored by Defense Advanced Research Projects Agency Contract Number DACA76-89-D-0002 (Field Operational X.500 Project), and U. S. Department of Energy Contract Number DE-AC03-76SF00098. 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 FTAM Implementation is available using FTAM.

NAME Alliance OSI(tm) X.500 Touch Communications Inc. LAST MODIFIED July, 1991 KEYWORDS API, Commercially Available, DSA/DUA, HP, IBM (Non-PC and RISC), MIPS, Macintosh, Multiple Vendor Platforms, OSI Transport, RFC-1006, Sun ABSTRACT Alliance OSI includes XDS (API), DUA, DSA and DIB all as separate components. Touch's X.500 products have been designed for complete portability to any operating system or hardware environment. The protocols include DAP and DSP of the OSI X.500 specification along with the required XDS, DUA, DSA and DIB components. In addition to X.500, Touch sup- plies other OSI protocol layers including: ROSE, ACSE, Presentation, Session and any of the OSI lower layers (Transport, Network along with RFC-1006). Touch also supplies other application layer proto- cols such as X.400, FTAM, CMIP (and general network management), etc. The Alliance OSI X.500 is compliant with the CCITT X.500 1988 Recom- mendations. The ROSE/ACSE/Presentation/Session stack can be option- ally provided by Touch. The DUA may represent a single user, or may represent a group of users. It may be attached to a given DSA within the same system but is also capable of invoking operations in Touch's or any other vendor's compliant DSA on a remote system. The binding operation requires the user to give a distinguished name and password in order for the Directory to identify the user. Once an association is esta- blished the user may invoke the following operations: READ, COMPARE, ABANDON, LIST, SEARCH, ADD_ENTRY, REMOVE_ENTRY, MODIFY_ENTRY, MODIFY_RDN.
Due to the fact that access to the physical disk is in most cases a blocking operation (synchronous) Touch has separated the database processing (I/O process) from the DSA protocol entity. This separa- tion allows the DSA entity to continue processing during the frequent database accesses from the DSA. The DSA supports all the Directory operations as specified in the CCITT X.500 specification. Chaining, Referral and Multicasting are provided and supported in the Alliance OSI DSA. The DSA supports all the service control options included in the operation command arguments. Filtering conditions are sup- ported via the FILTER in the SEARCH operation. The Alliance OSI X.500 product supports all the NIST defined manda- tory X.500 and X.400 object classes and attributes. Alliance OSI X.500 supports all the mandatory Directory attribute types (and their associated abstract syntaxes) in the NIST Directory implementation profile. Touch has extended the Directory and allows users to define private attributes. This means that a user can util- ize the Alliance OSI Directory for a general purpose, user defined database activity. Touch provides a full set of administration and Directory management facilities. Touch is in the process of integrating the X.500 product with the Worldtalk 400 product. Worldtalk 400 is Touch's end user X.400 mes- sage switch, providing gateways between proprietary mail systems (SMTP, Microsoft Mail, MHS, cc:mail, etc.) and X.400. X.500 is a key component for a messaging network. COMPLETENESS Strong Authentication is not supported however Simple Authentication is supported. INTEROPERABILITY No interoperability testing has been completed as of yet. PILOT CONNECTIVITY Numerous OEMs are using the Alliance OSI X.500 product in product development as well as in pilot networks. BUGS N/A
CAVEATS AND GENERAL LIMITATIONS Currently the Alliance OSI X.500 DIB has only been validated within a UNIX File System. The protocol components are portable as is the interface between the DSA and the DIB. INTERNETWORKING ENVIRONMENT Alliance OSI X.500 can be utilized over TCP/IP and/or OSI Transport on LANs and WANs. Currently X.500 has only been verified over OSI, however other Alliance OSI application layers have been configured over a RFC-1006 which is available as part of the Alliance OSI pro- duct line. HARDWARE PLATFORMS Alliance OSI has been ported to numerous platforms ranging from IBM Mainframes MVS to Apple Macintosh. For UNIX environments Touch has portations for 386 AT/Bus, SUN-3 and 4, Mips, and HP. SOFTWARE PLATFORMS As stated above, the Alliance OSI product have been ported to numerous systems. In the UNIX environment the X.500 product exists on SUN OS 4.0 and greater, Mips RISC OS, Interactive 386 and HP-UX.

NAME Custos National Institute of Standards and Technology LAST MODIFIED November, 1991 KEYWORDS API, DSA/DUA, Free, Limited Functionality, Multiple Vendor Platforms, Requires 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 3 workstations under the UNIX operating system. All underlying services are provided by the ISODE development package. The development pack- age is also used for encoding and decoding ASN.1 data as well as for other data manipulation services. Using the ISODE package the imple- mentation can be run over both OSI and TCP/IP protocols. The DSA provides full support for both DAP and DSP protocols, confor- mant 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 per- formance several options are supported that permit loading of selected portions of the database into 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. COMPLETENESS To date the Read, Compare, List, Add Entry, and Remove Entry opera- tions have been implemented and are supported over both DAP and DSP; aliasing and replication are also supported. The version under current development (available January '92) includes simple authenti- cation, access control, and the Search operation. The modify opera- tions and Abandon are not supported and there is no support for schema checking.
INTEROPERABILITY Have successfully interoperated with QUIPU and OSIWARE over the DAP. No DSP interoperability testing has been done. PILOT CONNECTIVITY Not tested. BUGS Some testing in the near term future will be done to try to identify these, but presently it's not possible to give an accurate list of bugs. 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 perfor- mance with a large database. Any platform the implementation can be ported to (generally any platform ISODE can be ported to) should sup- port all features. INTERNETWORKING ENVIRONMENT RFC-1006; TP4/CLNP (SunLink OSI) over 802 and X.25 (SunLink X.25). HARDWARE PLATFORMS It has been run on Sun-3, but there are no known reasons why it should not 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 6.0 and Sun OS version 4.1.1. Uses a locally developed relational DBMS that should be easily replaceable with commercially available relational systems. AVAILABILITY While under continuing development, availability of the implementa- tion is limited to organizations making appropriate arrangements with NIST. The implementation will be publicly available when development is completed.
NAME DCE/GDS (tm) Open Software Foundation, Inc. LAST MODIFIED July, 1991 KEYWORDS API, CLNP, Commercially Available, DEC Ultrix, DSA/DUA, IBM RISC, Multiple Vendor Platforms, RFC-1006, Source, X.25 ABSTRACT DCE/GDS (Distributed Computing Environment/Global Directory Service) was based on the original Siemens DIR.X product. It supports full DUA and DSA functions for globally unique identifications and for loca- tion of objects in the network. It also provides functions to answer queries (both yellow-page and white-page) about objects and attribute information. The software implements full DAP and DSP protocols specified in X.519. An ASN.1 compiler and required ACSE, ROSE, presentation, session and RFC-1006 protocols implementations are also included. The product has been successfully participated in X.500 Cebit Intero- perability tests at 1990 and 1991 Hanover Fairs. It also intero- perates with the ISODE QUIPU X.500 implementation. COMPLETENESS Compliant with EWOS Agreements which is being harmonized with 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 (version 1.0) and XOM (version 2.0) interface libraries are also provided. XDS and XOM interfaces are also used to access DCE/CDS (Local Cell Directory Service) transparently. A GDA (Global Directory Agent) serves as the gateway between the DCE CDS and GDS.
INTEROPERABILITY This implementation of DAP and DSP can interoperate with other X.500 implementations from other Cebit demo participants including IBM, HP, ICL, Bull, Nixdorf, etc. It also interoperates with ISODE QUIPU.

NAME DE COSINE PARADISE LAST MODIFIED November, 1991 KEYWORDS Available via FTAM, Available via FTP, DUA Connectivity, DUA Only, Free, Included in ISODE, Limited Functionality, Needs ISODE, Source, UNIX ABSTRACT DE (Directory Enquiries) is intended to be a simple-to-use interface, suitable for the naive user, and suitable for running as a public access dua to provide lowest common denominator access to the Direc- tory. It is a scrolling interface and will thus run on dumb termi- nals, even teletypes! The user is asked to fill in up to 4 questions per query: person's name; department; organization; country. The prompts are very verbose -- the intention is that the user should not be able get stuck, and information on how to get into the help system should always be on the screen. The help screens (of which there are 15) are aimed at the non-technical user. Whilst the outwards appear- ance of the interface is simple, a lot of attention has being given to mapping the strings the user enters onto X.500 operations in such a way that the interface seems to do the "right thing". An important characteristic is the way the interface tries a series of searches, gradually relaxing the matching criteria from exact (in some sense), to good, through to "fuzzy". A considerable amount of configuration is possible to present the results in locally acceptable formats. 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 188.8.131.52 and logging in as dua -- no password required. COMPLETENESS The interface is a querying engine only. INTEROPERABILITY DE is built with the ISODE software (release 7.0). Its interopera- bility relies on the correctness of the Quipu libraries.
PILOT CONNECTIVITY The interface is in use as the COSINE Central DUA Service, and is used by a number of UK institutions as a public access dua (usually over X.29). It is able to query entries in pilots throughout the world. It is not able to query for entries which are in organiza- tions beneath locality entries under country entries. It is not pos- sible to query for people who do not work for organizations. The interface only searches for entries of the following type: organiza- tions, organizational units, people, roles, and rooms. BUGS 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 will not query under localities immediately under the country level. It is not possible to display photographs or reproduce sound attri- butes. INTERNETWORKING ENVIRONMENT Same as ISODE. ISODE supports TCP/IP, TP0, and X.25. HARDWARE PLATFORMS Should be the same as ISODE in general. SOFTWARE PLATFORMS DE requires the ISODE (current release 7.0) libraries. AVAILABILITY DE is openly available as part of ISODE and as part of the COSINE DUA package. Available by FTAM and FTP, source code freely available.

NAME DISH-VMS 2.0 ACIDO Project LAST MODIFIED July, 1991 KEYWORDS Available via FTAM, Available via FTP, DUA Only, Free, Needs ISODE, RFC-1006, VMS, X.25 ABSTRACT This Directory User Agent interface was ported to the VMS operating system using ISODE 6.0. It is part of the results of collaboration project called ACIDO, between RedIRIS (national network R & D in Spain) and the "Facultad de Informatica de Barcelona (Universidad Politecnica de Cataluna)". The main objective of this development was to provide access to the directory to all those affiliated cen- tres to the Spanish National R & D network using VMS machines. Any other use of this software it is no within RedIRIS objectives and therefore it is not RedIRIS responsibility. COMPLETENESS The same as DUA (QUIPU 6.1). INTEROPERABILITY QUIPU 6.1 PILOT CONNECTIVITY Used in RedIRIS Directory Pilot Project to access the DSAs (QUIPU). BUGS You can report bugs to: email@example.com CAVEATS AND GENERAL LIMITATIONS The interface is equivalent to the UNIX one except for the option -pipe which is not supported.
