- It's not uncommon to see files with the owner field expressed in [ggg,mmm]
- format when the original owner has been removed from sysuaf, and the UIC now
- no longer exists. Not uncommon in an academic environment with a quarterly
- high turnover in accounts.
-
- What can also cause alot of confusion is when UICs are re-used. 'Leftover'
- files can turn up with 'un-privileged' ownership in areas that require
- privilege to create files. Causes great consternation in new inexperienced
- system administrators.
