setting root password has no effect in 3.6

[smorty]

I'm running 3.6 from ramdisk using toram install option.

Go to knoppix menu in kde and open root shell. Run passwd command to change
root's password. It reports that the password was successfully updated.

Open a separate terminal as user knoppix. Say "su -", expecting to be asked for root
password. It goes straight to root id without asking me for the password.

What do I need to do to fix this?

Edit /etc/sudoers so user knoppix requires a password to su. Defualt allows full sudoer privilages with no password.

su and sudo are different programs. sudoers does not affect the workings of su.

Can you provide any information on how to re-enable normal unix password authentication for suing to root from the knoppix account? I could really use it, I'm tearing my hair out over here.
