A potentially confusing situation can arise when su loses its SUID
magic. Please check that the permissions on your "su" binary look like
this:
$ ls -l /bin/su
-rwsr-xr-x 1 root root 52770 Oct 5 08:50 /bin/su
Listfolk; is there a reason why su doesn't check for "root"-iness before
jumping into the password prompt or PAM routines? By comparing EUID vs
UID or somesuch?
