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.
INTEROPERABILITY
Interoperability with ISODE QUIPU 6.0 has been tested, no formal test
suite was used.
PILOT CONNECTIVITY
Not tested: It should work in principle, but has not been tested.
BUGS
No known bugs at the moment.
CAVEATS AND GENERAL LIMITATIONS
Object identifiers for object classes and attribute types can
currently have only the form {2 5 6 x} or {2 5 4 x}, x<256. Changing
the directory schema requires code writing.
INTERWORKING ENVIRONMENT
RFC-1006 with TCP/IP, TP0 with X.25, TP4 with X.25 available by
agreement.
HARDWARE PLATFORMS
Sun-3, Sun 386, Apollo, a version of dua for IBM PC will be forthcom-
ing 1991.
SOFTWARE PLATFORMS

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.

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.
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
OSI environments with the complete OSI stack, supporting CLNS and
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
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.
xwp was developed at the University of Wisconsin - Madison Computer
Sciences Department. It is used in conjunction with the ECI mail user
agent project. xwp was written by Robert Lazarus, III.
