Thank you for your reply!

I'm not sure, if we're having the same issue, because:

- using rid instead of ad backend
- we've only 60 users and one group
- no nested groups of course
- timeout is always service ticket period. If it is set to 10 min.,
  timeout is after 10 min.
- there seems to be no timeout with NTLM auth, but haven't tested this
  for > 10 h
- I don't restart smbd
- it seems only version 4.5 from debian stretch is affected, not 4.8
  from Louis van Belle
- interruption is 100% all the time when kerberos is used
- doesn't matter how many connections are open. Only one connection on
  my test machine is sufficient.

Thank you for your script. Maybe I'll do some further tests between the
years.
