Multi Server VPN's using one login database and certificate

[whoda]

I have 2 vpn running on 2 centos VPS.

each time I add a user on openvpn, I also have to add user on another VPN because they are on different VPS.

My Question is can anyone guide me on how I can centralize the login and the certificate? where should I start? do i need to install fresh openvpn again? can anyone enlighten me cause i've been searching for weeks and still found no answer.

if you only use PKI, then you dont actually tell the server when you add new users, you just make sure you sign their certificate with the right ca.key
