no. we won't get a "getbackuplistreq" unless we are the local master
for that domain. It is a unicast request and is sent to hosts that
have answered a name query on DOMAIN<1D> or DOMAIN<1B>. So for Samba
to get one of those requests for a foregn domain we would first have
to become the LMB for the foreign domain. That won't happen. ok?

we won't get a getbackuplistreq for the foreign domain unless something
is severely broken.

which forced us to have a separate netbios alias for each domain.
We certainly don't want to do that in this case.

anyway, I think we agree that the code stays as it is, and users
wanting cross-subnet trust relationships should use a WINS server.
