IT did work after a restart, but only for about 5 hours before it failed
again - although this time instead of shutting down, it just didn't query
the IPA server any more?
Unfortunately debug had been set to 0 because everything had been working
well for so long, so I have nothing to show yet - I'll be doing more
forensics today.


We did find that rolling back the latest updates to the IPA server has
worked for returning auth. My manager is focused on "the problems with the
ipa server". I still think it was a problem on the specific client, since
my test unit and all other servers have continued working as far as we can
tell. It was unfortunate that the client in question was the cluster login
node.
