I have a situation at work where we need to migrate our NT4 domain into a native ADS domain. However, we have some applications which need to be integrated with this which do not support Samba 3 at the moment (ie. ClearCase). Would it be possible to run Samba 2.2.8 on our ClearCase (UNIX) server, and specify USER authentication with the SERVER entry pointing to a Samba3 machine which is a member of the ADS domain? In other words, can I use a SAMBA3 machine as an "authentication proxy" for clients using the NT4 authentication protocol? Thanks, Wolf Paul
