Yet again, why do you have the two lines above, they do not work on a
DC.

idmap.ldb, but it isn't a discrepancy, it is the default setting,
'Domain Users' is mapped to the Unix group 'users' in idmap.ldb

There is a bug report for this, until this is fixed, run 'net cache
flush' and then NEVER run 'getent group ANUMBER' again.
