Introduction
Introduction
This document has been produced to facilitate the interconnection of information
processing systems to provide directory services. The set of all such systems, together
with the directory information which they hold, can be viewed as an integrated whole,
called the Directory. The information held by the Directory, collectively known as the
Directory Information Base (DIB), is typically used to facilitate communication
between, with or about objects such as application entities, people, terminals and
distribution lists.
The Directory plays a significant role in Open Systems Interconnection, whose aim is to
allow, with a minimum of technical agreement outside of the interconnection standards
themselves, the interconnection of information processing systems:
•
from different manufacturers;
•
under different managements;
•
of different levels of complexity; and
•
of different ages.
To evaluate conformance of a particular implementation, it is necessary to have a
statement of which capabilities and options have been implemented for a given OSI
protocol. Such statement is called a Protocol Implementation Conformance Standard
(PICS).
This Recommendation specifies the PICS proforma for the Directory Access Protocol as
defined in ISO/IEC 9594: 1993(E) standard.
1 Scope
This Documentation provides the PICS proforma for the DAP specified in the ISO/IEC
9594 : 1993(E) standard. This PICS Proforma is in compliance with the relevant
requirements, and in accordance with the relevant guidance for PICS Proforma, given in
ISO/IEC 9646-7.
Details of the use of this Proforma is provided in Annex A of this Document
The scope of this Documentation is the specification of the conformance statements for
a Directory User Agent (DUA) and a Directory System Agent (DSA).
