ABSTRACT

   The DIXIE protocol is used to give X.500 access to platforms that
   have only TCP/IP access.  The DIXIE server is an intermediate proto-
   col server that communicates with Internet clients on one side using
   a text-based UDP/TCP protocol and an X.500 DSA on the other side
   using DAP.  The protocol is fully described in RFC 1246.  A subset of
   the X.500 DAP is exported to the clients through the DIXIE protocol.
   There is a DIXIE API provided in the form of a library of C-callable
   routines.

   The DIXIE protocol and server are being used by the following
   products/projects:

     UD, a simple command line white pages DUA for Unix machines (dis-
     tributed with the DIXIE server)

     maX.500, a white pages DUA for the Macintosh (available from the
     same place as the DIXIE server)

     Network monitoring of DSAs by our Network Operations Center

     Lookup and display of caller identification based on telephone
     caller ID (using ISDN).

COMPLETENESS

   The DIXIE protocol does not support access to all X.500 features and
   operations.  All DAP operations except Abandon are supported.  Gen-
   eral searches (including multiple component searches) are supported.
   The DIXIE protocol supports none and simple authentication.  A subset
   of the service controls are supported.

INTEROPERABILITY

   The current implementation of the DIXIE server works with the QUIPU
   DSA and DAP library.

PILOT CONNECTIVITY

   The DIXIE server has been tested in the Internet and PARADISE pilots.
   It provides full DUA Connectivity subject to the limitations dis-
   cussed above under completeness.

BUGS

   There are no known outstanding bugs.  But reports should be sent to
   x500@umich.edu.

CAVEATS AND GENERAL LIMITATIONS

   None, aside from those mentioned above under completeness.

INTERNETWORKING ENVIRONMENT

   DIXIE clients use TCP or UDP to communicate with the DIXIE server.
   The DIXIE server uses RFC-1006 with TCP/IP to communicate with the
   DSA, though other transport mechanisms for DSA communication should
   be possible.

HARDWARE PLATFORMS

   The DIXIE server is known to run on Sun 3, Sun 4, and DEC 3100 plat-
   forms.  It should run on any UNIX platform.  The DIXIE library is
   known to run on the same platforms, and also on the Macintosh.

SOFTWARE PLATFORMS

   The DIXIE server and library is known to run under SunOS 3.5, SunOS
   4.1.1, Ultrix 4.1 and 4.2.  The DIXIE library also runs on the Macin-
   tosh System Software 6 or later.

AVAILABILITY

   This software is openly available.  It may be obtained by anonymous
   FTP from terminator.cc.umich.edu in the directory ~ftp/x500. Documen-
   tation on the DIXIE protocol is provided along with the source code,

ABSTRACT

   DS-520 X.500 Distributed Directory Services for UNIX System V and
   DS-521 X.500 Directory User Agent (DUA) for UNIX System V form an
   integral part of the Retix OSI Networking Products family.  Designed
   for systems vendors, public carriers, and other OEMs, DS-520 is a
   complete high-performance implementation of X.500 in source code
   form, including a DUA, DSA Manager (DSAM), and DSA.  DS-521
   represents a subset of this product offering. It provides the DUA
   portal into the directory, which, for example, meets the needs of
   software vendors who plan to provide application packages with X.500
   Directory interaction capabilities. Within these two offerings, the
   DUA possesses two forms of interface. The first form, the DUA with
   User Interface, provides an interactive character-based user inter-
   face for users of Directory services.  The user agent provides access
   to the Directory via basic Directory service requests. The second
   form, the DUA with Programmatic Interface provides a standardized
   programmatic interface to application programs that must access
   Directory information. The interface is conformant to the X/Open
   Object Management (XOM) and X/Open Directory Services (XDS) stan-
   dards. This component provides all functionality related to Directory
   access and general OSI services down to the session layer. The DSAM
   provides an interactive character oriented user interface to a Direc-
   tory administrator.  The DSAM provides management functions either
   local to or remote from a DSA. Both the DUA and the DSAM are useful
   in the training, management, and manipulation of Directory entries
   maintaining operational and user attribute information. The DSA main-
   tains Directory database information and provides users the ability
   to read/compare, modify, search, and manage entries within the data-
   base. It maintains all or fragments of the Directory Information Base
   (DIB) and provides abstract service ports for DUAs and DSAs over DAP
   and DSP protocols respectively.

COMPLETENESS

   DS-520 represents a complete implementation of the 1988 X.500 Recom-
   mendations with the exception of strong authentication as outlined in
   X.509. It is conformant to NIST, EWOS, and UK GOSIP Directory pro-
   files. It provides session through application layer protocol support
   and hence incorporates ROSE, ACSE, Presentation, and Session within
   its product stack. In addition to including all the attribute types,
   syntaxes, and object classes defined in X.520 and X.521, the DS-520
   includes support for those specified in the 1988 X.400 Recommendation
   X.402, Annex A. Remote on-line management of the DSA is supported by
   means of Network Management Forum CMIP.

   DS-521 represents a complete implementation of the X/Open Object
   Management (OM) and X/Open Directory Services (XDS) standards. It
   also incorporates session through application layer protocol support
   and thus includes ROSE, ACSE, Presentation, and Session within its
   product stack.

INTEROPERABILITY

   The DS-520 has been tested to interoperate with Banyan (DAP), CDC
   (DSP), IBM, ICL, OSIWare, Nixdorff, Unisys (DSP), Wollongong (DAP),
   and 3-Com (DSP).

   The DS-521 subset has undergone no separate interoperability testing.

PILOT CONNECTIVITY

   DSA Connectivity provided by the DS-520: The DSA provides complete
   support for the X.511 Abstract Service Definition, the directoryAc-
   cessAC and the directorySystemAC defined in the X.519 Protocol
   Specifications, and the Distributed Directory defined in the X.518
   Procedures for the Distributed Directory. It supports all the object
   classes, attribute types, and attribute syntaxes defined in X.520 and
   X.521. It does not support the Internet DSP however.

   DUA Connectivity provided by both the DS-520 and DS-521: The DUA pro-
   vides complete support for the X.511 Abstract Service Definition and
   the directoryAccessAC defined in the X.519 Protocol Specifications.
   The DUA with User Interface supports only a subset of the X.500
   attributes and object classes defined in X.520 and X.521. The DUA
   with Programmatic Interface, however, does support all the object
   classes, attribute types, and attribute syntaxes defined in these two
   recommendations.

BUGS

   Product Action Requests (PARs) stemming externally from customers and
   internally from customer service and quality assurance engineers are
   generated and published in the form of weekly reports. A description
   and status of these PARs are provided to customers possessing
   software maintenance agreements.

CAVEATS AND GENERAL LIMITATIONS

   DS-520 and DS-521 are source code products ported to UNIX System V
   Release 3 and 4. Makefiles to generate the system are provided for
   the AT&T System V, SCO, and Interactive UNIX systems.

INTERNETWORKING ENVIRONMENT

   DS-520 and DS-521 offer two main compile time configuration options
   and hence internetworking configurations. In the first of these, they
   interface to the UNIX System V Transport Library Interface (TLI).
   The TLI provides a path between the session layer of a UNIX OSI
   application process and an OSI transport provider installed in the
   UNIX kernel. The latter transport provider may take the form of a
   Retix Unix LAN (LT-610) or WAN (WT-325) transport product. The second
   main option utilizes the UNIX System V ACSE/Presentation Library
   interface (APLI and the A/P Library), which provides OSI ACSE and
   Presentation layer services. The Retix AP-240 Presentation syntax
   manager product serves to map the standard Retix Presentation layer
   interface to the AT&T APLI. The APLI upper layers services may be
   provided by the Retix UL-220 product. UL-220 is the Retix implementa-
   tion of the AT&T Open Networking Platform Upper Layer Services module
   and includes the A/P library, as well as the OSI ACSE, Presentation,
   and Session services.

   DS-520 and DS-521 may also run on top of the TCP/IP stack by means of
   the Retix MP-120 product. MP-120 is a STREAMS based driver that
   implements RFC-1006 and thus allows OSI applications to run over a
   network based on the Internet suite of protocols (TCP/IP). Its main
   function provides a conversion between the TCP stream to the data
   packets required by OSI Transport Class 0 protocol and vice versa. As
   part of this process, it converts TCP/IP 32-bit addresses to hex
   values for use with OSI applications.

HARDWARE PLATFORMS

   Being source code products ported to the UNIX System V Release 3  and
   4  operating system environment, DS-520 and DS-521 are hardware plat-
   form independent. They currently both have sample portations and test
   configurations on various Intel 80386 platforms running Unix System V
   Release 3 and 4.

SOFTWARE PLATFORMS

   Currently, DS-520 and DS-521 include reference implementations for
   the AT&T System V Release 4, SCO UNIX System V/386 Version 3.2.2, and
   the Interactive UNIX System V/386 Version 2.2 operating systems.
   Raima Corporation's db_Vista III Version 3.1 serves as the database
   engine for the Directory product.

ABSTRACT

   HP's Distributed Directory Software is a fully distributed Directory
   that supports both the DAP and DSP protocols, which were specified in
   the 1988 CCITT/ISO X.500 documents.  Besides implementing the stan-
   dard, we have also put in proprietary access control and replication.
   These additional features will be migrated to the standard definition
   at the time that they are stable.  Users are able to define their own
   attributes, objects classes and DIT structure rules.

   In order to make this software easy to use a set of menu driven
   screens have been provided.  There are easy to use data access and
   data management screens.  For system administrators, these is also a
   set for screens that are used to help configure the servers and
   manage the schema. Startup and Shutdown utilities are also included.

   For application developers an X/Open-APIA XDS API is provided, along
   with some helper routines that help reduce development time.  The XDS
   API includes the following functions:

           Bind
           Read
           Search
           Add
           Remove
           Unbind
           Version

   A subset of the X/Open-APIA Object Management (XOM) functions are
   available thru the interface.  The subset are those that are neces-
   sary to perform the directory operations.

   For bulk operations a batch interface is also available.

COMPLETENESS

   This software implements the 1988 X.500 CCITT/ISO Standard.  It fully
   supports DAP and DSP, minus strong authentication.  By default it
   contains all of the X.520 Attributes and the X.521 Syntaxes and
   Object Classes.  Additionally, the Annex B DIT Structure can be
   enforced.

INTEROPERABILITY

   Interoperability testing will be undertaken as new X.500 products are
   introduced into the market.

ABSTRACT

   maX.500 is a Macintosh X.500 directory application useful for
   displaying and modifying white pages information about people.  It
   runs on top of the DIXIE protocol (described in RFC 1246).  maX.500
   is currently in production release 1.1 within the University of
   Michigan and several other places.

   Features include the ability to display and modify the following
   attributes: title, description, commonName, uid, mail, postalAddress,
   homePostalAddress, telephoneNumber, facsimileTelephoneNumber, home-
   Phone.  Photos can also be displayed.  The software also provides
   access to the finger protocol.  Various preferences are user-
   tailorable, including caching.

COMPLETENESS

   maX.500 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.

CAVEATS AND GENERAL LIMITATIONS

   maX.500 is heavily oriented to white pages information and thus gen-
   eral access to the DIXIE protocol is not provided.

INTERNETWORKING ENVIRONMENT

   maX.500 uses the DIXIE protocol and thus TCP to communicate with the
   DIXIE server.  The Macintosh needs to have MacTCP installed.

ABSTRACT

   OSI-DSA provides a Directory System agent for controlled access to
   the OSI Directory Information Base.  It provides full support for the
   joint ISO/IEC IS-9594 International standard and CCITT X.500 Recom-
   mendations 1988 protocols necessary for implementing the Directory
   Information Base distributed across a number of DSA's.

   The product also includes an Administration User interface program,
   to allow a human administrator to construct and maintain the local
   Directory Information.

   Specific features provided by the Directory System Agent include:

       (i)    Support of the directoryAccessAC and directorySystemAC
              application contexts (i.e. both Directory Access Protocol
              (DAP) and Directory System Protocol (DSP)

       (ii)   Bind Security levels of none and simple unprotected.

       (iii)  Capability of acting as a first level DSA.

       (iv)   Support for chaining and multi-casting where necessary in
              handling distributed operations. Also supports the return
              of referrals.

       (v)    Support for all attribute types and syntaxes defined in
              X.520.  Users are also able to define their own attributes
              and syntaxes.

       (vi)   Support for all the object classes and attribute sets
              defined in X.521.  Users are also able to define their own
              object classes and attribute sets.  Support is also pro-
              vided for a NAME-BINDING specification, for defining the

              Directory Information Tree (DIT) structure.

       (vii)  An access control mechanism based on the ISO  access  con-
              trol  working  papers  to  allow for controlled access and
              maintenance of Directory entries and attributes.

       (viii) Logging of errors and significant Directory events, as
              well as optional trace information.

       (ix)   The OSI-DSA utilizes the services of ROSE (X.219) and ACSE
              (X.217) as defined in clause 8 of X.519

   The Administration program provides the following functions

       (i)    An interface to each of the basic Directory Operations of
              Read, Compare, List, Search, Add, Modify, ModifyRDN.

       (ii)   A Dump/Load utility to dump the information in the local
              DIB into an ASCII file and load it again into the DIB from
              such a file.

       (iii)  Knowledge Reference maintenance facilities to Add, Delete
              Modify and Read all types of Knowledge References.

       (iv)   Facilities to control the operation of local Directory
              processes.

       (v)    Control over the level of logging and tracing.

COMPLETENESS

   formant to, the joint ISO/IEC IS-9594 International standard and
   CCITT X.500 Recommendations 1988, and the NIST 1988 Stable agreements
   on Directory Services.

   The only exception is that no support is provided for strong authen-
   tication or digital signatures.

   Conformance with respect to clause 9 of X.519:

       (i)    The DSA supports both the directoryAccessAC and directo-
              rySystemAC application contexts.

       (ii)   The DSA is capable of acting as a first-level DSA.

       (iii)  The chained mode of operation as defined in X.518 is sup-
              ported.

INTEROPERABILITY

   The product was demonstrated at "Interop 91" in San Jose, October
   1991 as part of the OSI Showcase demo involving several vendors'
   directory products.

   Informal interoperability has been achieved against the ISODE 6.0
   QUIPU Directory implementation.  Interoperability testing against
   other vendors is in progress.

   Formal interoperability testing is awaiting the soon to be completed
   OSInet X.500 interoperability test suite.

PILOT CONNECTIVITY

   Not tested.

BUGS

   Full customer support is provided via your local Unisys Customer Ser-
   vices Organization.

CAVEATS AND GENERAL LIMITATIONS

   Results returned via the OSI-DSA are presently limited to 32K in the
   current release, which is in line with the 1988 NIST agreements.

   Patches for the Unix V.4 release may be made available on request to
   raise this limit to 1Mb.

   The product currently does not provide any support for replication,
   although development work is in progress, based on the current ISO
   Draft proposal for Replication.

INTERNETWORKING ENVIRONMENT

   OSI-DSA runs over all communications environments supported by the
   Unisys OSI stack product (see Software platforms). Currently these
   support TP0, TP2, TP3 and TP4 over X.25 and TP4 over CLNP on 802.3
   and X.25.  Support for RFC1006 over TCP/IP is under development.

HARDWARE PLATFORMS

   The product is available on all Unisys Unix 6000 Series machines.

   Source code is available for portation to non-Unisys platforms.

SOFTWARE PLATFORMS

   The product is distributed and supported for Unix System V.3 and Unix
   System V.4.

   On Unix V.3, it requires the Unisys Application Presentation Service
   OSI stack software (APS), and Unisys Transport Network Service
   software (TNS).  On Unix V.4, it requires the integrated Unisys OSI
   stack software product (STK).  These services are accessed via the
   ROSLI (ROSE) and APLI (ACSE) programming interfaces which are
   currently the subject of standardization efforts by XOpen and Unix
   International.

   A runtime version of either the Informix or Oracle relational data-
   base products is required for the Directory Information Base.

ABSTRACT

   OSI-DUA is a Unix C Program interface library. It allows OSI or user
   applications to access the services of an X.500 conformant Directory,
   by making calls to a library of C routines.

   Specific features provided by this program interface library are as
   follows:

       (i)    Connection to any remote X.500 conformant DSA via an OSI
              stack, or connection to a co-resident Unisys OSI DSA via
              IPC mechanisms.

       (ii)   All operations defined in the directoryAccessAC applica-
              tion context (Bind, UnBind, Read, Compare, Search, List,
              AddEntry, ModifyEntry, ModifyRDN, Abandon, DeleteEntry).

       (iii)  Directory Bind security levels of none and simple unpro-
              tected.

       (iv)   Execution of both blocking and non-blocking operations.
              (A non-blocking call to the library will return immedi-
              ately, allowing for results to be obtained once the opera-
              tion has completed)

       (v)    Acceptance of multiple concurrent non-blocked operations
              on the one user session.

       (vi)   The DUA utilizes the services of ROSE (X.219) and ACSE
              (X.217) as defined in clause 8 of X.519

COMPLETENESS

   When communicating with a Remote DSA the DUA library is fully confor-
   mant with the Directory Access Protocol detailed in the X.500
   Recommendations/IS-9594 standards.

   Conformance with respect to clause 9 of X.519:

       (i)    All operations defined in the  directoryAccessAC  applica-
              tion  context  (Bind, UnBind, Read, Compare, Search, List,
              AddEntry, ModifyEntry,  ModifyRDN,  Abandon,  DeleteEntry)
              are supported.

       (ii)   Directory Bind security levels of none and  simple  unpro-
              tected are supported.

       (iii)  The directoryAccessAC application context is supported  as
              specified in clause 7 of X.519.

       (iv)   The DUA conforms to the mapping onto used services as  de-
              fined in clause 8 of X.519.

INTEROPERABILITY

   Informal interoperability has been achieved against the ISODE 6.0
   QUIPU Directory implementation.  Interoperability testing against
   other vendors is in progress.

   Formal interoperability testing is awaiting the soon to be completed
   OSInet X.500 interoperability test suite.

CAVEATS AND GENERAL LIMITATIONS

   The present OSI-DUA does not provide for the  automatic  handling  of
   referrals  by  the  interface library. However interface routines are
   provided which allow referrals to be acted upon by the user  applica-
   tion.

   The present OSI-DUA provides a proprietary C  programming  interface.
   An XOpen XDS conformant interface is currently under development.

INTERNETWORKING ENVIRONMENT

   OSI-DUA runs over all communications environments supported by the
   Unisys OSI stack product (see Software platforms). Currently these
   support TP0, TP2, TP3 and TP4 over X.25 and TP4 over CLNP on 802.3
   and X.25.  Support for RFC1006 over TCP/IP is under development.

ABSTRACT

   POD (POpup Directory) is an X.500 DUA interface for the X Window Sys-
   tem.  POD is a first attempt at a multiwindow directory tool. It
   offers a simplified interfaces to the basic X.500 operations of read,
   search, list and modify entry.

   POD 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.

   POD 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: POD is in use in many directory pilots, certainly
   including PARADISE and the Internet.

ABSTRACT

   psiwp is a Macintosh Front End to White Pages service.  It is a
   graphical user interface implementing a partial-DUA.  It is based on
   the ISODE QUIPU X.500 implementation and the Directory Assistance
   Protocol (DAP).

   psiwp is a Macintosh application tailored specifically to provide
   easy access to the Directory for the purposes of performing White
   Pages searches.  Implements User-Friendly Naming scheme developed in
   IETF OSI-DS Working Group.

   psiwp implements a Directory Assistance Protocol (DAP) client.

COMPLETENESS

   Compliant with X.500 standards to the extent that the QUIPU implemen-
   tation is.

INTEROPERABILITY

   Successfully interoperates with QUIPU DSAs

PILOT CONNECTIVITY

   Being used in the White Pages Pilot Project.

BUGS

   Support is available (for registered users of psiwp only) from
   psiwp-help@psi.com.

CAVEATS AND GENERAL LIMITATIONS

   psiwp is not a general-purpose DUA. It was designed to be a special-
   purpose front-end for performing White Pages searches and thus, in
   the interests of simplification, does not provide the full range of
   functionality supported by the X.500 standard. A Directory Assistance
   server (available as part of the ISODE distribution) must also be run
   by sites that do not want to run psiwp against either of the two
   White Pages Pilot Project service machines, wp1.psi.net and
   wp2.psi.net.

INTERNETWORKING ENVIRONMENT

   Runs on Macintoshes as a Finder or MultiFinder application.

HARDWARE PLATFORMS

   Runs on Macintoshes that support MacTCP. Requires an ethernet board
   or AppleTalk connectivity. At least 1MB of memory is required, and
   while psiwp will run on most forms of Macintoshes, a Mac-II is recom-
   mended.

SOFTWARE PLATFORMS

   Requires MacTCP 1.0 or later, and Finder (or Multifinder) 6.x (Finder
   7.0 WILL NOT WORK). Requires ISODE Version 6.8 or later.

AVAILABILITY

   psiwp is shareware available for anonymous ftp from uu.psi.com
   [136.161.128.3] in pilot/PSIWP.Hqx.  A nominal fee is charged upon
   registration as a PSIWP user.
