[kalilac]

Hello peaplo.
I am with a great problema.
I have two SaMBa´s configured who server (security = user) and a NT each 
other clients.
I want put this three servers to talk each  other and the clients inside 
with one coud access the resources of other domain like the NT do.
My machines. 

Samba1 = domain1
Samba2 = domain2
NT           = domain3 

Each one have diferrents users but I want make a trust interdomain 
relationship.
What I need do into mine SaMBa´s??
Thanks
