CentOS - Oct 2013 - How to list openvpn clients?

I'm running an openvpn server on a CentOS machine -
that is my excuse for posting my query here -
and I'm wondering if there is some way of finding
all the clients (not just those connected at this moment)
who have been registered as clients of the openvpn server?

Did you configure ifconfig-pool-persist...?

All users should have a key in /etc/openvpn/easy-rsa/2.0/keys
So that might be one source of usernames.

Also look through /etc/openvpn/server.conf . There might be a line
which verifies usernames, for example, from the OpenVPN 2 Cookbook:
   tls-verify /etc/openvpn/cookbook/example6-5-tls-verify.sh
so you'd need to look at that file and example6-5-tls-verfiy.sh.allowed

There are other possibilities that list all allowed users.  See the
Cookbook.
