Noting with care the following paragraph:

PAM is used to set the policy su(1) will use.  In particular, by default
only users in the ``wheel'' group can switch to UID 0 (``root'').  This
group requirement may be changed by modifying the ``pam_group'' section
of /etc/pam.d/su.  See pam_group(8) for details on how to modify this
setting.

which may well be why the OP keeps stressing that his unprivileged user
is not in the wheel group.  ;-)
