OVERVIEW
The ATN directory service (ATN DIR) application allows ATN users to obtain directory information about ATN users, applications and services participating in the ATN. The ATN DIR is composed of three parts: a directory information base, directory system agents (DSAs) and directory user agents (DUAs).
The ATN DIR provides generic directory services over the ATN internet. It may also be used as a directory system supporting user applications communicating over the ATN. This may be achieved, for example, by means of application programmme interfaces.
The ATN DIR is provided by the implementation over the ATN internet communication services of the directory services specified in ISOIIEC 9594 and CCITT or ITU-T X.500, and complemented by the additional requirements specified in this manual. The ISOIIEC directory services international standards and the ITU-T X.500 series of recommendations (1993 or later) are in principle aligned with each other. However, there are a small number of differences. In this manual, reference is made to the relevant ISO International Standards and ISPs where applicable.
