[Samba] Interdomain trust with different WINS servers

I have tried with lots of lmhosts formats, but it looks nmbd is ignoring the
lmhosts file when trying to resolve hostnames using nmblookup. nmblookup
gives the correct data when the name of the machine is in the DNS server.

So now, i wonder if the trust relationship could be done using entries of
DNS server, but i don't know what format must have these entries in the ldap

I know the documentation says that all servers must use the same WINS
server, but in our case this is impossible. All we can do is configure Samba
so the WINS server all use the same DNS server.

Any idea or help how to configure this?
