Hi,

Looks good to me, but I wonder if the long standing quirk of ignoring
the "primary Group ID" RFC2307 attribute and honouring Windows-side
group settings for primary group too is still in effect and
must be someway described in the wiki page (it affected Winbind for
sure, never tested SSSD).

I think (and reported about two years ago on this list) that up to
Samba 3.5.0 the behavior was different (primary group taken from
POSIX attributes in RFC2307 fields), but changed afterwards and could
be the culprit behind:

https://bugzilla.samba.org/show_bug.cgi?id=8694

https://bugzilla.samba.org/show_bug.cgi?id=7582

https://bugzilla.samba.org/show_bug.cgi?id=8905

I even started an (aborted, unfortunately) effort at adding back the
former behavior through a configuration option (totally rewritten id mapping
plugin structure made the relevant information "unavailable where needed"
and would so require a substantial development work beyond my possibilities atm).

Regards,
Giuseppe
