LDAP - Lightweight Directory Access Protocol

LDAP (Lightweight Directory Access Protocol) is an Internet protocol used to access directory services.  At BNL, the term LDAP is used interchangeably to refer to both the protocol and the information it provides.  At BNL LDAP is generally used as an address book for email clients that cannot or do not connect to the Microsoft Exchange server.

How to access LDAP services

There are many different programs with LDAP functionality built in.  Rather than provide specific documentation for all possible packages, the general information for LDAP configuration will be provided.  Below is a list of settings.  Some or all may be required, depending on the software package.  In your software program of choice, enter the following information:

Base DN: dc=bnl,dc=gov
Port number: 389
Scope: Subtree
Search filter: (objectclass=*)
