Comment 23 for bug 1179955

Rob -- did you issue this OSSN already? If not ..

May need to clarify Memcache without DB backend ( in "If you deploy using Memcache .." ), where flushing cache would resolve the issue. If there is a DB behind it, your next paragraph with DB script necessary to clean up.

And given Chmouel's fix has been committed .. please add

 "Patch addresses the issue and will be part of the next official release of OpenStack/Keystone. "
