As user 'bob' I can run /usr/BIN/redhat-config-network (btw, shouldn't this be fedora-config-network) and nothing happens (i.e. no su'ish prompt). If I 'strace /usr/BIN/redhat-config-network' it magically works... that is the user is prompted for root's password. redhat-config-network works fine as root, AND /usr/SBIN/redhat-config-network works FINE as user 'bob' with NO authentication. User 'bob' is only a member of group 'users'. Wtf? -Jim P.
