The Lightweight Directory Access Protocol (LDAP) server database is a repository for
employee directories. These directories include the names of employees along with various
types of personal data such as a phone number, email address, and other information that is
exclusive to the individual employee. The LDAP database is composed of objects containing
attributes and values. Each object name is referred to as a distinguished name (DN). The
location on the LDAP server where a search begins is called the Base Distinguished Name or
base DN.
