It looks like the SL 7 samba security updates break IPA when applied onto an
IPA server:
Apr 21 14:00:32 systemd[1]: Starting Samba SMB Daemon...
Apr 21 14:00:33 smbd[2121]: [2020/04/21 14:00:33.520169, 0]
../../source3/passdb/pdb_interface.c:171(make_pdb_method_name)
Apr 21 14:00:33 smbd[2121]: No builtin nor plugin backend for ipasam found
This is because the IPA updates are not part of the security updates and then
the IPA plugin for samba is out of sync.
Updating fully to SL 7.8 resolved the issue for me.
