The add-on for Lync Server may cause performance degradation in ActiveRoles. A symptom of the issue is slowness and high resource consumption of operations related to retrieval of user attributes from ActiveRoles, especially when enumerating a large number of user accounts (several thousands).
Active Roles Add-on for Lync Server 2.1 has been released to resolve this issue.
The following defects are also resolved in this release:
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.
The add-on for Lync Server may stop the ActiveRoles Administration Service from incorrectly processing requests to retrieve all properties of a particular user account. As a result, the Administration Service returns only Lync Server user properties while requested to return all properties. A symptom of the issue is that the objet returned by the Get-QADUser -Proxy -IncludeAllProperties command does not contain the sAMAccountName property.
