The search queries you specify are available to all listeners you configure on the system. 

The root level of the directory is called the base. The name of the base is the DN (distinguishing name). 
The base DN format for Active Directory (and the standard as per RFC 2247) has the DNS domain 
translated into domain components (dc=). For example, example.com's base DN would be: dc=example, 
dc=com. Note that each portion of the DNS name is represented in order. This may or may not reflect 
the LDAP settings for your configuration.

If your directory contains multiple domains you may find it inconvenient to enter a single BASE for your 
queries. In this case, when configuring the LDAP server settings, set the base to NONE. This will, 
however, make your searches inefficient.
