This description is meant to be a fairly short introduction about how to set up a Samba server so that it can participate in interdomain trust relationships. Trust relationship support in Samba is at an early stage, so do not be surprised if something does not function as it should.

Each of the procedures described next assumes the peer domain in the trust relationship is controlled by a Windows NT4 server. However, the remote end could just as well be another Samba-3 domain. It can be clearly seen, after reading this document, that combining Samba-specific parts of what's written in the following sections leads to trust between domains in a purely Samba environment.
