ABSTRACT

   QUIPU is part of the ISODE which is an openly available implementa-
   tion of the upper layers of OSI.  QUIPU provides a X.500 Directory
   System Agent (DSA) and a set of Directory User Agents (DUA) aimed at
   different terminal types and modes of interaction

   QUIPU was first publicly demonstrated at ESPRIT in November 1988.
   QUIPU is being used extensively in the European PARADISE project, the
   White Pages Pilot Project and the Australian pilot.  A QUIPU DSA is
   being used at the ROOT node of the Pilot DIT and is being used as
   most country level DSAs.

   QUIPU provides its own solutions to area not specified by the 1988
   standards such as replication and access control.

COMPLETENESS

   QUIPU is aligned to the 1988 ISO IS and the NIST OIW Directory Imple-
   mentors Guide Version 1, with the following exceptions:

       Strong authentication is not implemented.

       QUIPU does not enforce the bounds constraints on attributes,
       filters or APDU size.

       T.61 string formatting characters are not rejected.

       If a DN is supplied with no password in an unprotected simple
       bind, QUIPU does not always check to see if the DN exists.  If
       the DSA connected to can say authoritatively the DN does not
       exist, the association is rejected.  However, if a chain opera-
       tion is required to check the DN, the bind IS allowed.

Top       Page 66 
       When comparing attributes of UTCtime syntax, if the seconds field
       is omitted, QUIPU does not perform the match correctly (i.e., the
       seconds field in the attribute values should be ignored, but  are
       not).

       QUIPU always supplies the optional Chaining argument ``origina-
       tor'' even if the CommonArgument ``requestor'' is used.

       QUIPU always supplies the optional Chaining argument ``target''
       even if the base object in the DAP arguments is the same.

       The object class ``without an assigned object identifier'' is not
       recognized unless the ``alias'' object class is also present.

       Non Specific Subordinate References are never followed by a QUIPU
       DSA, but they are passed on correctly to the client if generated.

INTEROPERABILITY

   QUIPU has interworked with a number of other implementations, and has
   no know problems in such interworking.

PILOT CONNECTIVITY

   QUIPU is in use in many directory pilots, certainly including PARAD-
   ISE and the White Pages Pilot Project.

BUGS

   Problems should be reported to quipu-support@cs.ucl.ac.uk.

CAVEATS AND GENERAL LIMITATIONS

   None.

INTERNETWORKING ENVIRONMENT

   QUIPU users TP0 over X.25, CONS and TCP (using RFC-1006) or TP4 over
   SunLink OSI.

   The DSA knows about the problems of unconnected networks and makes
   chain/refer choices based on the network connectivity.  Using this an
   X.25 only DSA can access data from an Internet only DSA by chaining
   operations through a DSA connected to both networks.

HARDWARE PLATFORMS

   [No information provided--Ed.]

SOFTWARE PLATFORMS

   The ISODE and QUIPU runs on native Berkeley (4.2, 4.3) and AT&T Sys-
   tem V, in addition to various other UNIX-like operating systems.  No
   kernel modifications are required.

AVAILABILITY

   The ISODE is not proprietary, but it is not in the public domain.
   This was necessary to include a "hold harmless" clause in the
   release.  The upshot of all this is that anyone can get a copy of the
   release and do anything they want with it, but no one takes any
   responsibility whatsoever for any (mis)use.

DISTRIBUTION SITES

   The FTP or FTAM distributions of ISODE-7.0 consists of 3 files. The
   source and main ISODE-7.0 distribution is in the file isode-7.tar.Z
   which is approximately 4.7MB in size.

   LaTeX source for the entire document set can be found in the isode-
   7-doc.tar.Z file (3.5MB).  A list of documents can be found in the
   doc/ directory of the source tree.

   A Postscript version of the five volume manual can be found in the
   isode-7-ps.tar.Z file (4.7MB).

   1.  FTP
          If you can FTP to the Internet, then use anonymous FTP to
          uu.psi.com [136.161.128.3] to retrieve the files in BINARY
          mode from the isode/ directory.

   2.  NIFTP
          If you run NIFTP over the public X.25 or over JANET, and are
          registered in the NRS at Salford, you can use NIFTP with usen-
          rame "guest" and your own name as password, to access
          UK.AC.UCL.CS to retrieve the files from the <SRC> directory

   3.  FTAM on the JANET, IXI or PSS
          The sources are available by FTAM from UCL over X.25 using

                  JANET (DTE 00000511160013),
                  IXI   (DTE 20433450420113) or
                  PSS   (DTE 23421920030013)

Top       Page 68 
          all with TSEL "259" (ASCII encoding). Use the "anon" user-
          identity and retrieve the files from the src/ directory. The
          file service is provided by the FTAM implementation in ISODE
          6.0 or later (IS FTAM).

ABSTRACT

   SD (Screen Directory) is an X.500 DUA interface for character mapped
   screens.  SD is an early attempt to provide quick, easy and user
   friendly access to the Directory.  The following directory operations
   are supported: read, search and list.

   SD does not provide any sophisticated access to the DSA.  Operations
   are performed synchronously.  The Directory is thus presented as is,
   i.e.  a hierarchical tree of information, with the user required to
   "navigate" the DIT in order to locate required information.

   SD is available as part of the ISODE release from version 6.0
   onwards.

COMPLETENESS

   88 standard: strong authentication not implemented

INTEROPERABILITY

   Believed to be compliant, though untested.

PILOT CONNECTIVITY

   DUA Connectivity: SD is in use in many directory pilots, certainly
   including PARADISE and the Internet.

KEYWORDS

   API, Bull, Commercially Available, DEC Ultrix, DSA/DUA, HP, IBM PC,
   IBM RISC, Multiple Vendor Platforms, Philips, RFC-1006, Siemens, Sun,
   UNIX, X.25

ABSTRACT

   UCOM.X 500 includes a Directory System Agent (DSA), a directory
   access API, and a set of Directory User Agents (DUAs) for different
   terminal types. UCOM.X 500 is a commercial product based on PIZARRO,
   the research prototype developed at INRIA by Christian Huitema's
   team.

   Some characteristics of the DSA are:

       - The DAP and DSP protocols are provided conformant with the 1988
       CCITT X.500 recommendations.

       - The DIB is maintained in ASN.1 encoded format in the Unix file
       system. Utilities are provided to load and dump the DIB from and
       to ASCII text files.

       - The DIT structure is held in main memory. Additionally, fre-
       quently used attributes may be held in inverted tables in memory
       to speed up searches.

       - Knowledge management: knowledge on managed domains is stored in
       UCOM.X specific attributes of the DSA entries.

       - All X.500 (88) as well as some X.400 (88) object classes,
       attributes and syntaxes are supported. Users may define their own
       classes and attribute types.

       - Schema management: object class and attribute definitions are
       enforced.

       - Simple authentication is provided; strong authentication is not
       currently supported.

Top       Page 74 
       - Access control: private mechanisms are provided to allow access
       control lists to be specified for parts of the DIT, to control
       modifications, and to specify access restrictions on attributes.

   The UCOM.X 500 API provides the DAP protocol to applications access-
   ing the Directory. It is a synchronous API which automatically
   manages referrals. Several DUAs using the API, are available. These
   include command line and full screen interfaces for users with ordi-
   nary terminals, and an X-Windows user interface (12/91). An X/Open
   XDS API will be offered shortly.

   UCOM.X 500 is used by French research centers involved in PARADISE, a
   COSINE project. A distributed application to control document
   transfer in a large French hospital, has been built on the UCOM.X 500
   API. It is being used for distributed applications management in the
   French Post Office.

COMPLETENESS

   UCOM.X 500 conforms to 1988 X.500 series of recommendations, as
   specified in paragraph 9 of X.519, with the exception of strong
   authentication.

INTEROPERABILITY

   Interoperability tests with other implementations, e.g. QUIPU, have
   been made in the PARADISE project. UCOM.X 500 is used in the French
   PARADISE pilot.

PILOT CONNECTIVITY

   DSA and DUA connectivity to the PARADISE pilots.  See caveats.

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 is stored in main memory which means that the order
   of magnitude of the number of objects supported per DSA is 10,000. By
   1992 100,000 objects will be supported.

   Not all syntaxes defined in the COSINE and Internet Schema are
   currently supported, and the DUAs do not display photo attributes.
   The Internet DSP is not supported.

Top       Page 75 
INTERNETWORKING ENVIRONMENT

   UCOM.X 500 uses RFC-1006 with TCP/IP and TP0 with X.25.

HARDWARE PLATFORMS

   UCOM.X 500 runs on: Sun 3, Sun 4, IBM RS 6000, Philips P 9000, DEC
   machines, Bull DPX 2000, HP 9000/300, Siemens IN 6000 and 386-based
   PCs.  It can easily be ported to any UNIX machine.

   Windows 3 and Macintosh DUAs will be available by Spring 1992.

SOFTWARE PLATFORMS

   UCOM.X 500 is portable to any UNIX-like operating system. It has been
   ported to: AIX, UNIX System V.3, SUN OS 4, Ultrix, HP-UX, SCO Unix,
   Interactive, BOS (Bull Operating System), and SPIX.

   The UNIX file system is used to hold the DIB.

ABSTRACT

   ud is a command line based directory application useful for display-
   ing and modifying white pages information about people.  It runs on
   top of the DIXIE protocol (described in RFC 1246).  ud was developed
   to run under Unix and is currently in beta release within U-M staff
   and a few other places that have heard of it.

   Features include the ability to display and modify the following
   attributes: title, description, commonName, uid, mail, postalAddress,
   homePostalAddress, telephoneNumber, facsimileTelephoneNumber, home-
   Phone.

COMPLETENESS

   ud uses the DIXIE protocol to access X.500 and thus is subject to the
   same completeness restrictions as DIXIE.  It provides Read, Search,
   and Modify capabilities.

INTEROPERABILITY

   Works with the DIXIE server, which works with the QUIPU DSA and DAP
   library.

PILOT CONNECTIVITY

   It has been tested (in conjunction with the DIXIE server) in both the
   Internet and PARADISE pilots.

BUGS

   No outstanding bugs are known.  But reports should be sent to
   x500@itd.umich.edu.

Top       Page 77 
CAVEATS AND GENERAL LIMITATIONS

   ud is heavily oriented to white pages information and thus general
   access to the DIXIE protocol is not provided.

INTERNETWORKING ENVIRONMENT

   ud uses the DIXIE protocol and thus TCP to communicate with the DIXIE
   server.

HARDWARE PLATFORMS

   ud is known to run on Sun 3s, Sun 4s, and Vaxen.

SOFTWARE PLATFORMS

   SunOS 3.5, SunOS 4.1.1, BSD 4.3 Unix.

AVAILABILITY

   This software is openly available.  It may be obtained by anonymous
   FTP from terminator.cc.umich.edu in the directory ~ftp/x500.

ABSTRACT

   VTT X.500 contains a full distributed DSA and a subroutine call to
   dua ( call_dua(parameters)). This subroutine is linked to user's pro-
   cess.  There are two ways for dua to communicate with our DSA called
   dsacvops: a fast communication through shared memory for dua and dsa
   in the same computer and a complete OSI-stack for communicating in
   DAP-protocol with remote dsa's which can be any implementation of
   X.500 dsa, not necessarily dsacvops.  DSA communicates with other
   dsas through a full OSI-stack with protocol DSP or with a shorter
   stack when both dsas are dsacvops-processes.  dsacvops contains a
   special purpose database DIB. VTT X500 contains caching of read and
   search results, access controls (as in Annex F of X.501), object
   classes and attribute types as in X.520 and X.521 and simple authen-
   tication with unprotected passwords in bind. The network level can be
   X.25 or TCP/IP. There are test duas, duacvops, duauser, with a simple
   user interface. Certificates for strong authentication are included
   to x509dua and x509duacvops. VTT X500 is realized with program
   development tools CVOPS and CASN, the code is in C-language and uses
   UNIX System V. The code is fairly easy to port to other operating
   systems.  VTT X500 was made for Smail e-mail product of Nokia Data
   Systems.

COMPLETENESS

   Complete DAP and DSP of 1988 X.500 Recommendations are implemented.
   There are the following omissions: multicasting is not implemented,
   strong authentication of calls to dsa (optional signing of DAP and
   DSP-calls, strong authentication in bind, security error, security
   parameters in common arguments), T61 alternative in CASE IGNORE and
   CASE EXACT STRING, Criteria-syntax, TeletexTerminalIdentifier syntax.

ABSTRACT

   WIN/DS is an implementation of OSI Directory Services aligned with
   the ISO 1988 X.500 IS and NIST Stable Implementors Agreements. WIN/DS
   includes both a Directory User Agent (DUA) and a  Directory System
   Agent (DSA). The product supports all Directory Services operations,
   object classes and attributes.  It provides support for managing the
   Directory Information Tree (DIT) with facilities to control structure
   rules and their enforcement.  WIN/DS also provides solutions to areas
   not specified by the 1988 standards, such as replication and access
   control.

COMPLETENESS

   Wollongong closely follows the NIST OIW Stable Implementors' Agree-
   ments.  See also QUIPU.

INTEROPERABILITY

   WIN/DS has interoperated with other X.500 implementations at trade
   shows (CeBIT and Interop) and at strategic customer sites.

   X.500 DUA process

LAST MODIFIED

KEYWORDS

   Window System, X.25, 3Com

ABSTRACT

   The DUA process runs on 3Com's dual-stack OSI/TCP terminal server,
   scheduled to be released in mid-June 1991.  It provides Presentation
   Address resolution for names, on behalf of the VTP application: when
   the user attempts an outgoing connection ("VTP <name>" or "connect
   <name>"), <name> gets mapped to its Presentation Address.

   The DUA process supports the AddEntry, RemoveEntry, and Search opera-
   tions.  Via a menu-driven command, the system administrator can con-
   figure any of these operations, then send the request to the DSA.  He
   would use the AddEntry operation to enter a resource name and its
   corresponding physical address in the DIB, the DeleteEntry operation
   to remove the name and its physical address, and the Search operation
   (with "filter" as an option) for a display of all registered names
   or, given a name, a display of the name's physical address.

   Regarding unbinding from a DSA, the system administrator could use an
   UnbindDSA command or set a timer which, once expired, would automati-
   cally perform the unbinding.  The binding to a DSA, on the other
   hand, is transparent, provided the system administrator has set a DSA
   address.  The binding is triggered by either an outgoing connection
   attempt or an operation request sent to the DSA.

   The schema supported by the DUA consists of the following sequence of
   object classes: Country, Organization, OrganizationalUnit (up to 3
   levels of OrganizationalUnits are allowed), ApplicationProcess, and
   ApplicationEntity.  Their respective attributes are CountryName,
   OrganizationName, OrganizationUnitName, CommonName, and Presenta-
   tionAddress.  The CommonName of the ApplicationEntity is always "vt"
   for VTP and is transparent to the system administrator.

Top       Page 86 
COMPLETENESS

   Compliance with the ISO/IEC 9594 standards.
   Handling referrals not yet implemented.
   Schema supported: Country, Organization, OrganizationalUnit,
                     ApplicationProcess, and ApplicationEntity.
   Authentication not supported.

INTEROPERABILITY

   Interoperability with the ISODE QUIPU Directory Service and any DSA
   which strictly meets the ISO/IEC 9495 standards.

BUGS

   [No information provided--Ed.]

CAVEATS AND GENERAL LIMITATIONS

   Deleting an entry will fail if the DUA is interacting with a 6.0
   based version of QUIPU.  This is a bug in QUIPU, and version 7.0
   release will have it fixed.

   Adding a CountryName is disallowed if the DUA is bound to QUIPU.
   This decision was made because to add a country in QUIPU, one needs
   to bind as the manager of the DSA holding the root EDB file, and such
   information may not always be available to the system administrator.
   Also, our binding is done transparently.

INTERNETWORKING ENVIRONMENT

   TP4.

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 dif-
   ferent 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.

COMPLETENESS

   The Xdi interface does not support accesses to Delete and Add DAP
   operations as in the 88 Directory Standard. Read, Search, and most
   Modify operations are fully supported. There are no facilities to
   modify the RDNs of entries. Strong authentication is not implemented.

INTEROPERABILITY

   Believed to be compliant. Only tested against ISODE/QUIPU DSAs.

HARDWARE PLATFORMS

   This software has been tested on SUN4. It is expected that the
   software is portable to SUN3 and other UNIX machines.

SOFTWARE PLATFORMS

   Xdi is expected to run on ISODE (release 6.8 upwards) in UNIX
   environment.  The 'xdi' directory has been designed to fit directly
   into the ISODE source tree. Xdi requires X11R4, the associated Xt
   toolkit and Athena widget libraries.  Also see the operating environ-
   ments of ISODE.

AVAILABILITY

   The Xdi software is available via anonymous FTP from
   thumper.bellcore.com in file pub/xdi.tar.Z. Source code and execut-
   ables can be freely distributed or modified for non-commercial and

ABSTRACT

   Xds is a DUA designed for users who have little or no knowledge of
   X.500. Its intended to be used, for example, by a receptionist who
   has to answer such queries as 'Could I have the telephone number of
   Andrew who works in Research?'. The display is customized for the
   particular organization and the results of the search are presented
   in the format of a business card. It is possible to customize the
   displayed information.

COMPLETENESS

   Xds does not provide user access to all the services provided by
   X.500.  Instead, Xds uses X.500 services to provide the specific
   functions for which it is designed to provide.

   Conforms to section 9 of X.519.

ABSTRACT

   The xdua is a DUA designed to be used by DSA managers who have suffi-
   cient X.500 knowledge to manipulate the Directory Information Tree
   (DIT). It's typical use is to maintain the information stored on a
   DSA. The xdua has a Macintosh style interface.  This simplifies
   browsing the DIT hierarchy.  A user can traverse the DIT levels by
   using a standard mouse.  The xdua supports the X.500 operations of
   add, modify, delete, search and show.

COMPLETENESS

   Uses the QUIPU (ISODE) dsap interface to provide the X.500 opera-
   tions.

ABSTRACT

   The xwp program is a simple browser for the QUIPU/X.500 directory.
   It uses OSF/Motif and the X Window System to provide a convenient
   user interface.

   The user interface consists of five different top-level windows: the
   main window, the search window, and three option windows.  The main
   window appears when the program is executed and all others are
   reached through its menus.  The main window contains Current Loca-
   tion, Current Descendents, Descendent Filter, Current Information,
   and Directory Status subwindows.  The contents of these subwindows
   show information about the current location of the browser in the
   directory tree.  The search window contains Search Area, Search
   Filter, and Search Results subwindows.

   The mouse pointer may be used in the main window to change the
   current location of the browser in the directory tree.  We can des-
   cend deeper into the tree by clicking the mouse when it points to a
   member of the Current Descendents list.  Doing this "moves" the
   browser to this new (one level deeper) location in the directory
   tree.  This causes the main window to be updated as follows: (1) the
   selected descendent becomes the new Current Location, (2) its descen-
   dents are listed in Current Descendents, and (3) its contents are
   displayed in Current Information.  Any problems and messages from the
   directory are displayed in the Directory Status portion of the main
   window.  To move the browser up the directory tree (i.e. towards the
   root), click the mouse pointer on one of the components of the
   Current Location.  In this way it is possible to move the browser to
   any location above its current position (i.e. to any ancestor) in one
   mouse click.  Doing this causes the main window to be updated as dis-
   cussed above.  Due to directory-imposed limits, it may not always be
   possible to display all the descendents of the current position.  In
   such cases (and others) it may be useful to impose a filter on the

   descendents to be listed.  To do this, position the mouse pointer in
   the Descendent Filter box and use the keyboard to type in the desired
   filter expression.  Typing <RETURN> in this box causes the Current
   Descendents list to be updated using the new filter.
