That's useful to know, thank you.
Going back to my original two boxes, it turns out they do have the same UID
and GID for the user I'm testing with - although one does have a slightly
different set of supplementary groups (it's running ubuntu 11.10 instead of
However by trawling logs I did finally work out the problem:
08/06/12 17:51:22 ERROR: the submitting host claims to be in our UidDomain (int.example.com), yet its hostname (192.168.6.8) does not match. If the above hostname is actually an IP address, Condor could not perform a reverse DNS lookup to convert the IP back into a name. To solve this problem, you can either correctly configure DNS to allow the reverse lookup, or you can enable TRUST_UID_DOMAIN in your condor configuration.
So, reverse DNS (or /etc/hosts entries) are required for UID_DOMAIN to be
honoured. It's working now.
Many thanks for the pointers!
