Solution is to use the keytab file if exists and if using it fails, try to remove an recreate one before failing and giving auth error.

My original code left the user.keytab alone, not adding new lines to it with kadmin commands. This failed to authenticate for reasons I do not understand. Resolved problem by creating new keytab and replacing old one with it after success. Tested overnight with submissions every 10 minutes.

- Target version changed from v0.3 to v0.3.1
testing revealed that issue was not resolved, but operational load is no worse than before . Operational workaround is to delete the (username).keytab and ask them to resubmit. I have saved off an example of the keytabs which I can use to reproduce the problem and resolve it in the server code.

generating user keytab invalidates users keytab on all the other servers.
Resolution is to generate them in a central place and distribute them along with running auth.py from this branch
