Nope, thats not going to help. The basic problem is: You won't get a
ticket (with pac and all) for windows clients from a non AD KDC, period.

What you *can* do is join a windows client to samba4 and get a ticket
(been there, done that). To actually use the ticket for your services
you'd need other kerberized services and hence service principals in the
samba4 KDC. Haven't tried to do this, same for the possible cross-realm
/trust scenario.

hope I'm not totally off base here ;)
