The following is a list of issues resolved in this patch.
Add-on for Lync Server may cause performance degradation in ActiveRoles Server. A symptom of the issue is slowness and high resource consumption of operations related to retrieval of user attributes from ActiveRoles Server, especially when enumerating a large number of user accounts (several thousands). The issue is due to a defect in the policy scripts installed by the add-on.
Back-sync of existing Lync Server user accounts takes much longer than expected to complete. When initially syncing Lync Server user accounts that were configured without using this add-on (so-called "back-sync"), the add-on's "Lync Server - Perform Full Sync" task marks them as sync-pending. As a result, a large number of user accounts are waiting for unnecessary delta-sync steps, and cannot be managed by the add-on until the delta-sync steps are completed. A symptom of the issue is a large number of user accounts stalled in the "Lync Server - Users - Sync Pending" Managed Unit during the initial back-sync.
