Joe - need some clarification for repro:

did the "admin" tenant already exist when you made the request to remove it, or is this an instance of failure of removing a tenant that didn't already exist?

shouldn't give a traceback either way, but I'd like to know to categorize this issue appropriately. For the sake of completeness, could you also specify the command you used with the client to generate this?

Ran into this today. It applies to almost every *-delete command except for service-delete. Keystone should be returning 404 instead of 500 in this case.
