In fact, I do have host names instead of IP addresses of the NIS servers in the
client configuration.

We have been using this without problems for many years. Problems only appeared
with the jump to openSUSE Leap 15.1 .
Further I wonder why the problem only manifests for a few users while most of
the users don't hit the problem.

Nevertheless, I contacted one of the affected users and will verify it with IP
addresses of the NIS servers instead.
