Bug 1809147

Description of problem:
I wanted to give homed a try, now that it is in Fedora 32. User creation and logging in fail due to SELinux, but that can be worked around with `setenforce 0`. Also, logging in fails due to bug 1806949, this needs to be adjusted in PAM.

Afterwards, logging in generally works, but there is no valid group for the user

Version-Release number of selected component (if applicable):

systemd-245~rc1-3.fc32.x86_64

How reproducible: Always


Steps to Reproduce:
1. Disable SELinux (setenforce 0) and adjust PAM config as in bug 1806949
2. Create user:
   sudo homectl create test --real-name="Test User"
3. Check that NSS knows about it:
   id test
   (prints "uid=60444(test) gid=60444 groups=60444" for me)
4. Log in:
   su - test

Actual results:

step 3) group of user test does not have a name
step 4) there is a warning message
/usr/bin/id: cannot find name for group ID 60444

Expected results: There should be a proper default group for created users, with the same name.


Note that specifying explicit group memberships works:

$ sudo homectl create rtest --real-name="Test Admin User" -G wheel
$ id rtest
uid=60471(rtest) gid=60471 groups=60471,10(wheel)

I can log in as rtest and run sudo.
