Yeah.  Group 513 on the AD level is the group "Domain Users" which should
always exist.  It looks like all LookupAccountSid requests to your primary
machine domain fail for some reason.

This is group 513 of the local SAM.  This is not related.

That's a good question.  The problem is that I can't see *why* the
requests fail.  This bugs me since failing LookupAccountSid calls should
result in a debug message when running strace.

Do you have changed your /etc/nsswitch.conf file by any chance?

Would you mind to create strace output of the command `id'?
