Chapter 25 LDAP Queries

Working with LDAP Queries

You create an entry in the LDAP server profile for each type of LDAP query you want to perform. When

you create LDAP queries, you must enter the query syntax for your LDAP server. Please note that the

queries you construct should be tailored and specific to your particular implementation of LDAP

directory services, particularly if you have extended your directory with new object classes and attributes

to accommodate the unique needs of your directory.
