A while back I installed OS X Lion Server and migrated some data across from Snow Leopard Server. When I accessed the server using "Server Admin" and to my shock noticed that 5 accounts (displayed in the format of UUID) in the Access list. All the real users are accounted for. I can't see these accounts being used in any other application, other than the "Access" tab in "Server Admin".
What tools on OS X Lion Server can I use to determine whether these are real accounts, or perhaps something left over when I migrated data from Snow Leopard Server?
