Issue: Some Identity Manager drivers are not intended to connect to an application. For such drivers, the engine does not retrieve an application schema because there is no connected application. Therefore, the driver shim returns an empty schema to the engine. The engine considers it as a missing schema and displays the following warning:
DirXML Log Event -------------------
Driver: \Org_Tree1\system\services\idm\Driverset1\Timed Job
Status: Warning

Workaround: Ignore this warning for the drivers that are not connected to an external application.
