Hi, I just got a comment from one of my IBM support engineeres that there is a problem with auth-passwd.c only calling authenticate() once.

Ok, to keep things short. Im wondering if I need a secondary relationship table to handle my many-to-one relationships. Here is an example of what I''ve written down.

I'm sure this has been discussed before, but would it then be possible to join a "real" NT4 or Win2k BDC to the Samba domain and establish the trust relation from our other Win2k? Or does the trust relationship have to be "registered" with the entire domain and therefore all the domain controllers? Khanh Tran Network Operations Sarah Lawrence College 1 Mead Way
