When updated path for single sign-on the path in cookie is same as before even the path attribute show changed path. When reload/restart server the path in cookie is changed to new path. The problem is nothing indicate to reload/restart server as it does in other cases by changing "process-state" status. Only resource description of sso is mentioning the reload by "restart-required" => "all-services". So the server should be showing that it's need to be reloaded/restarted. Other sso attributes probably have same problem but not tested.
