Failing nodes: nichtsalsverdrus (Fedora LXQt)

Summary

Users with UIDs of the IPA range and not the typical Linux user range (1000+) weren't shown in the login screen and one cannot type a user name either.

Steps to reproduce

Log out and have a look at the login screen of the LXQt (SDDM) Fedora.

What is the current bug behavior?

No users shown with too large UID (until workaround)

What is the expected correct behaviour?

All users selectable as login users.

Possible fixes

Fixed it (but not in ansible and not with a good upper limit, but only a value that is larger than the largest UID that is in use and small enough to show users. If the UID is too large no user is shown at all.

In the /etc/sddm.conf one has to add the following lines:

HideUsers=nfsnobody
MaximumUid=1911111111

and restart sddm/Xorg.
