I doubt that will work unless ad.domain happens to resolve to an
address somehow. The mount.cifs program doesn't have support for
recognizing an AD domain in the host portion of the UNC.

Also, mounting DFS referrals directly has some problems at the
moment. Igor posted a patch to prevent oopses from that, but I think
we probably need to consider a more complete solution.
