Q. What's the maximum number of LDAP Agreements configurable in CCM 7.x?
A: You can configure up to 5 LDAP agreements. As per the Cisco Unified Communications Manager 7.x SRND, the synchronization is performed by a process called Cisco DirSync, which is enabled through the Serviceability web page. When enabled, it allows one to five synchronization agreements to be configured in the system. An agreement specifies a search base that is a position in the LDAP tree where Unified CM will begin its search for user accounts to import. Unified CM can import only users that exist in the domain specified by the search base for a particular synchronization agreement.

Q.Is there any way to make User ID only numeric and not alphanumeric?
This parameter specifies whether the user ID to be used is alphanumeric or numeric. Valid values specify True (user ID is alphanumeric) or False (user ID is numeric).
This is a required field.
Q.Is there anyway to allow a user to force off another EM session?
This parameter specifies the behavior for multiple attempted logins by the same user on different devices within the same cluster. Allowed values are : 1. Multiple Logins Allowed (the same user ID can be logged in to extension mobility on more than one device), 2. Multiple Logins Not Allowed (a user ID can only be logged into one device) and 3. Auto Logout (if a user ID is logged into extension mobility on one device, and the same user ID attempts to login to extension mobility on a different device, the first device automatically logs out). For EM Cross Cluster, multiple login is always allowed.
