This time activities are somewhat reversed. Again, we'll assume that your domain controlled by the Samba PDC is called SAMBA and the NT-controlled domain is called RUMBA.

The very first step is to add an account for the SAMBA domain on RUMBA's PDC.

Launch the Domain User Manager, then from the menu select Policies, Trust Relationships. Now, next to the Trusted Domains box, press the Add button and type in the name of the trusted domain (SAMBA) and the password to use in securing the relationship.

The password can be arbitrarily chosen. It is easy to change the password from the Samba server whenever you want. After you confirm the password, your account is ready for use. Now its Samba's turn.

Using your favorite shell while logged in as root, issue this command:

root# net rpc trustdom establish rumba

You will be prompted for the password you just typed on your Windows NT4 Server box. An error message, "NT_STATUS_NOLOGON_INTERDOMAIN_TRUST_ACCOUNT," that may be reported periodically is of no concern and may safely be ignored. It means the password you gave is correct and the NT4 server says the account is ready for interdomain connection and not for ordinary connection. After that, be patient; it can take a while (especially in large networks), but eventually you should see the Success message. Congratulations! Your trust relationship has just been established.
