This is more an advice for when you're doing a new VPN setup ...

Ask yourself if you really need the CA layer at all - if you would skip
it if you could.  If the answer is "Yes, please!", then you should look
into the feature which I believe arrived in OpenVPN 2.6

     --peer-fingerprint

That just requires clients to have the server-side certificate
fingerprint listed and the server the fingerprints of all the clients it
accepts.  And that's it.  Both clients and servers will need the
key/cert files, but the certs can now be self-signed.

There will be a lifetime on the client/server certs itself - so you need
to consider carefully how long you want your client and server
certificates to be valid.
