Configuring LDAP Servers

The Lightweight Directory Access Protocol (LDAP) enables users to access contact information over a network. Users can share the same contact information. A typical application of LDAP is a single address book for all employees in a company, that all employees can access.

To configure your LDAP servers, click on the Directory Servers icon in the left pane of the Settings dialog. Table 12–14 lists the dialog elements that you can use to configure your LDAP servers.
