Ignore PAM just now (or indeed forever); 'su -' should work ok without it. Do you have the parameter 'SU_WHEEL_ONLY' set in /etc/login.defs ? If so, to what value? Can you login as root directly on tty1 ? What happens if you create the 'wheel' group and put your own non-root username into it? After that, can you 'su -' ok? If not, can you 'su' (without the '-') ok? rgds, akh -- -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
