Active Roles Web Interface generates error "SIP user name must be specified" when saving changes made to the Lync user account.
SIP user name for the Lync user account is not populated.
The SIP user name must not be empty. Fill up the SIP user name before making changes to the Lync user account. SIP user name generation rule can be configured within Active Roles to auto generate the SIP user name based on the defined conditions.
