Suppose you want (for whatever reason) to see the Samba users as UNIX 
users: you'll put something like "passwd: files winbind" in 
AFAICT that's not going to work on the machine (phyisical, virtual, 
jail, etc...) where Samba is configured to be an AD DC (*).
I'm not sure why, I think it has something to do with the way winbindd 
works, which is different on the DC.

So I use a jail for the DC (where I'll have no need for UNIX users) and 
configure any other instance be a domain member.

(*) Notice "AD DC"; it will work on an NT DC.

The only nuisance is the need to use that jail for DNS.

I never investigated (yet), so I can't answer.
It's also possible I've fallen behind and bhyve now works well.

(Leaving aside bhyve specific problems, which, as I said earlier, I'm 
not entitled to consider), I don't think there would be any problem: 
that's what I'm doing with jails.

Why? I thinks the community might benefit from this... let them decide :)
