In Cisco Unified Communications Manager Administration, use the menu path to configure LDAP authentication.
The authentication process verifies the identity of the user by validating the user ID and password/PIN before granting access to the system. Verification takes place against the Cisco Unified Communications Manager database or the LDAP corporate directory.
You can only configure LDAP authentication if you enable LDAP synchronization in the LDAP System Configuration window.
User accounts must be synchronized with Cisco Unified Communications Manager to use LDAP authentication. Administrators must enable LDAP synchronization and configure LDAP directory instance(s) to use the LDAP authentication mechanism.
When both synchronization and LDAP authentication are enabled, the system always authenticates application users and end user PINs against the Cisco Unified Communications Manager database. End user passwords get authenticated against the corporate directory; thus, end users need to use their corporate directory password.
When only synchronization is enabled (and LDAP authentication is not enabled), end users get authenticated against the Cisco Unified Communications Manager database. In this case, the administrator can configure a password in the End User Configuration window in Cisco Unified Communications Manager Administration.
