Encountered an error while attempting to perform an LDAP search for all Office Communications Serve

OCS_User_Replicator_30015_EE (Rule)

Encountered an error while attempting to perform an LDAP search for all Office Communications Server attributes on a user object. The error was serious enough to warrant stopping synchronization, which means that if this error is not corrected, no more user updates will be pulled from AD and into the Office Communications Server database.

Summary

Causes

This event occurs for a variety of reasons. The most common are either the domain controllers going down, or the server running out of memory.

Resolutions

Check for failures in the domain infrastructure. Because the User Replicator automatically retries the operation, when the error is resolved, the User Replicator will automatically start synchronizing again.
