So, you have configured CUCM for LDAP synchronization and defined an LDAP directory.  However, LDAP authentication is a separate configuration. With Business Edition, if you want to use LDAP authentication for Unity Connection then this would require that you configure LDAP synchronization AND LDAP authentication within CUCM.  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.  Details are as follows:

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.
