Comment # 1 on bug 1219503 from Johannes Meixner

It seems this is old leftover stuff
that needs to be cleaned up:

cups.spec contains (excerpts - long line wrapped here):
-----------------------------------------------------------
getent group ntadmin >/dev/null || %{_sbindir}/groupadd 
 -g 71 -o -r ntadmin
-----------------------------------------------------------
and
-----------------------------------------------------------
%dir %attr(0775,root,ntadmin) %{_datadir}/cups/drivers
-----------------------------------------------------------

cups.changes contains (excerpt):

- added creation of group ntadmin in %pre (bugzilla#45719)
-----------------------------------------------------------
where (bugzilla#45719) is
https://bugzilla.suse.com/show_bug.cgi?id=suse45719
"ntadmin is not in passwd"
(excerpts):
--------------------------------------------------------------
Directory /usr/share/cups/drivers is owned by group "ntadmin",
but this group isnt added any more through samba package.
Therefore installation of cups package complains about
non existing group.
...
The directory might be used by cupsaddsmb.
And it should be part of the cups package.
--------------------------------------------------------------

On my openSUSE Leap 15.5 system with CUPS 2.4.7
/usr/share/cups/drivers is empty.

Furthermore cups.changes contains (excerpt):
-----------------------------------------------------------
- Version upgrade to 2.3b6:
...
  Backward incompatible changes:
  * The cupsaddsmb program has been removed (Issue #5449)
-----------------------------------------------------------
where "Issue #5449" is
https://github.com/apple/cups/issues/5449
"Drop cupsaddsmb and Samba PPD file support"
(excerpts):
-----------------------------------------------------------

The Windows PostScript driver is long unsupported
and Samba 4 doesn't support cupsaddsmb. Remove it.
