I've wrote
Code:
auth sufficient pam_wheel.so trust group=vsxg0 use_uid
as the first line in /etc/pam.d/su file, but user vsx0 (from group vsxg0) still requires password when doing su.

What's wrong? It works nice on all other distros I've tried (Ubuntu, RedHad, Asianux, SUSE, Mandriva).

P.S. I'm working on Xandros Server 1.0 (30 days trial)
