Known issues
1. There is a known issue where doing a User Drive Mapping, when a User is created, and before it is provisioned, if the master jobs run, you will get a "Unknown type of content returned:'xxx'" error. In order to fix this you will need to make sure the user is provisioned, delete the child job with the user, and then reset the master job and run it again. It will create a new job with the correct information so the issue no longer occurs.
