It is, but not in the way you think.  The issue is that we need it to
forward DNS queries between the two forests, for the trust to be set up
correctly.  While I've currently set up a hack (attached) to make it
forward between the two servers, this may break other things.  

The autobuild got as far as a smb2.notify test failing, that may or may
not be related:
[432(1779)/1870 at 50m34s] samba3.smb2.notify(nt4_dc)
maximum runtime exceeded for smbtorture - terminating
UNEXPECTED(error): samba3.smb2.notify.basedir
REASON: Exception: Exception: was started but never finished!
UNEXPECTED(error): samba3.smb2.notify.basedir(nt4_dc)
REASON: was started but never finished!
