LDAP Architecture Overview

The Lightweight Directory Access Protocol (LDAP) is the newest addition to the list of Solaris naming services. Although included in the Solaris 8 release, it is an optional naming service that can coexist with legacy Solaris naming services. LDAP shares some characteristics with NIS and NIS+, but it is more sophisticated in the way data is structured and the methods used to access data.

LDAP's complex architecture is easier to explain if we divide it into the four models it supports and describe each model separately, as we do in the following sections. The four models are:

  1. Information Model
  2. Naming Model
  3. Functional Model
  4. Security Model

Each of these models are discussed in the following sections.
