winbind needs to take care of finding DC's and keeping connections open to
domain controllers anyway. Opening many persistent SMB connections to DC's is
not an option, there might be *many* of them. I've seen an installation with
500 resource domains all trusting a single central user domain. Every resource
domain was equipped with PDC and BDC, and the (older) winbinds on those opened
3-4 connections to the 2 central DC's each. That just killed the central
DC's. This installation started the rpc redesign in Samba3. So in Samba4 I'd
rather not make this mistake again and re-use SMB connections as much as I

So I'd rather vote for winbind providing the services everybody needs via
irpc than everybody opening connections himself.

You know how I think about backwards compatibility. :-)
