You should also make sure they're not loged in at the time, look for
files in /var/spool and /tmp/, etc. Tools such as ssh-agents that live
in /tmp/ will wind up with interesting uid issues, and processes that
are running and active as that user may have interesting issues as
well.
*THIS* is why it's so much more robust to set up your uid's and gid's
well in advance and consistently across a network, and keep them out
of the lower, auto-assigned ranges.
