Note: The instructions below will configure the required exemption for Mozilla Firefox on an Active Directory network to allow RM Unify Single Log Out to function correctly. They will guide you to create a policy object which applies to all computers on your Active Directory network. If you wish to position the policy elsewhere in your Active Directory structure, you may do so.
