Dunno. But the output is NOT the same:
# dpkg -i openvpn_2.2.1-5_i386.deb
# hardening-check /usr/sbin/openvpn /usr/lib/openvpn/openvpn-down-root.so
/usr/lib/openvpn/openvpn-auth-pam.so | grep yes
/usr/sbin/openvpn:
Position Independent Executable: no, normal executable!
Stack protected: yes
Fortify Source functions: yes (some protected functions found)
Read-only relocations: yes
Immediate binding: no not found!
/usr/lib/openvpn/openvpn-down-root.so:
Position Independent Executable: no, regular shared library (ignored)
Stack protected: no, not found!
Fortify Source functions: no, only unprotected functions found!
Read-only relocations: no, not found!
Immediate binding: no not found!
/usr/lib/openvpn/openvpn-auth-pam.so:
Position Independent Executable: no, regular shared library (ignored)
Stack protected: no, not found!
Fortify Source functions: no, only unprotected functions found!
Read-only relocations: no, not found!
Immediate binding: no not found!

The difference is clear. Plugins get "Fortify Source functions:" and
"Read-only relocations:". Only openvpn-auth-pam.so gets "Stack
protected", but I'm not an expert on this issue so I don't know the
reason for that.
