Prevent multiple login with the same certificate

Hi.
I'm wondering if there's a way to block a connection coming from a client having the same cert of an already connected client, before the connection has been enstablished.
Reading the config doc I saw the default behaviour is dropping an already connected client when a new client connects using the same certificate, but this is not what I'm looking for.

Any suggestion?

I doubt we have the same issue because we do it the right way.

As for your initial question, this cannot be done with stock openvpn.
You could hack the source code or maybe script some weird behavior ..
