gdb ended up aborting while trying to do the stack trace when the problem
occurred (https://bugzilla.redhat.com/show_bug.cgi?id=1162264) so I haven't
had any luck there.

It seems to be a problem with one of my servers only.  I've shut it down and
the user can authenticate fine against our backup server.  I tried restoring
from backup with bak2db but that didn't appear to help.  Is there a more
restore from scratch procedure I should try next to see if it some kind of
corruption?
