Behavior of the UCServer on the Microsoft Active Directory


If the ActiveDirectory in the UCServer is used for user management, the users are temporarily stored in the adcontacts.db database in the program directory under \database. Aevery 20 seconds, the UCServer checks the HighestCommittedUSN in the Active Directory and if something has changed, the latest changes are read in from AD and the adcontacts.db is updated.
A complete synchronization is performed once a day. This synchronization is documented in the LOG file EventLog_<Date>_<Time>.txt in DEBUG mode. It then says "Performing automatically triggered full sync of user profiles."

The synchronization interval with the Active Directory of 20 seconds cannot be changed.
