They sure did make me suspicious. Especially because the condor user existed
on each host with the same uid and gid.

Actually, these lines where the ones that made me suspicious enough to write
a short C program to call getpwnam to make sure it wasn't something on my
system. After that worked and reported the correct uid and gid, I went back
to trying different versions of condor. Which eventually proved to be the
answer. :D
