Does this need to be an application flag, or can it be in the krb5.conf
realm configuration?  Presumably people are currently working around
this by setting [capaths] on the server; a realm variable would simplify
this workaround by not requiring specific knowledge of the domain geometry.

I reviewed the thread, and it sounds like the current understanding is
that AD applies a transited check (of sorts) to cross-realm tickets, but
 doesn't say so by setting the transit-policy-checked flag in the
ticket.  From the upstream point of view the server's realm
configuration is in a better position to know that the realm is an AD
realm than the server application; perhaps that is not true from Samba's
point of view, but I thought I would check.
