Looks like the proposed configuration in /etc/pam.d/su limits the use of "su" to users in the "wheel" group. You may try to do "usermod -a -G wheel <user>" (as root). We should update the text in the warning... Or comment out the "auth required pam_wheel.so use_uid" line in /etc/pam.d/su, adding "# Uncomment the following line if you want to limit su to users in the wheel group."
