I really appreciate the trouble you're going to.

O.k. I'm used to that from OpenLDAP backends.

I'm willing to replicate the DIT or otherwise promulgate it, as long as
the original remains intact.

I don't know what universal groups are. This must be a Windows thing and
I haven't got that far yet ;)

I can't see that happening either; moreover the Samba 3 docs warn
against expecting this.

O.k., summa sumarum: "Samba 4 is coming along and both the sam/ldb
backend and the total concept are necessarily going to be different from
that in Samba 3. However, we, the Samba designers, have the interests of
the present user and machine park at heart and at the same time as we
are presenting a totally new Samba concept, are striving toward making
the transition from 3 to 4 as painless as possible". At the same time,
you're going to have to up your demands on the OpenLDAP (at least)
backend and its capabilities and educate your users in its
configuration. Dunno whether I'd like that job ;)
I'll stick around, you don't have to tell me any more for the time
being. Renewed thanks for taking the time and trouble!
