No, there shouldn't be. Can you generate sssd logs on the instance that
is acting up and send them to me? It's best to run date and expire the
cache before the test as well:
    sss_cache -E; date; ssh user@host; date
so that we can cross-check the logs knowing the time of the test. If you
don't mind I'd like to share the logs with other SSSD developers because
I think I already tried to look into this issue and couldn't find the root
cause in the past, so maybe others will spot something..
