Your Cisco Unified CallManager 5.0 cluster is using your corporate Windows 2003 Active Directory for user information. Over the weekend you updated the Windows 2003 Active Directory Server and added a small group of new users. Cisco Unified CallManager is configured to synchronize with the Active Directory server every 8 hours and it has been 32 hours since the last successful synchronization. The configuration on Cisco Unified CallManager did not change during the Active Directory server upgrade and the remainder of the Windows network is functioning properly.
What are two possible causes of this synchronization issue? (Choose two.)
A. The synchronization on the AD server was set to manual.
B. The domain controllers are down.
C. There is a username and or password mismatch between the Cisco Unified CallManager cluster and the Windows AD server.
D. Authorization has not been configured for a third party LDAP service.
E. The LMHOSTS file has been corrupted.
