Donald,
Is there any reason why you have installed OpenVPN using rpm?
Unless there is a very good reason you should always install using yum
It's available in the epel repo.
$ yum info openvpn

Description : OpenVPN is a robust and highly flexible tunneling application that
: uses all of the encryption, authentication, and certification
: features of the OpenSSL library to securely tunnel IP networks
: over a single UDP or TCP port. It can use the Marcus Franz Xaver
: Johannes Oberhumer's LZO library for compression.
So if I were you I'd start again and undo what you have done already if that's possible.
then as su do a
yum install openvpn
then read the manual
man openvpn
