1. Introduction

The OSI Directory [1] provides a powerful infrastructure for the

retrieval of information objects. This infrastructure can be used to

support, e.g., white pages applications, application entity lookup,

and so on.

The Directory service is provided to applications through the

Directory Access Protocol (DAP), which binds a Directory User Agent

(DUA) to a Directory System Agent (DSA).
