Hmmm... given my findings, it might be a good thing to have a 'diag' tool that can do things like check for the presence of the ghostUser, possibly even create/associate/map one in the event that one is missing. (I fully realize that this is NOT something that 'should' happen in the first place, but might still be something worth having). I'm sure there are similar types of things that could be added to it as well.
