Setting up Remote Access VPN using third party certificate.

We currently have a couple of remote access VPN's using pre-shared keys but need to transition those to using certificates in the near future.  User authentication is provided by RSA tokens.  We have 5510 ASA at another location that I am using as a test bed to configure a remote access VPN using a third party certificate.  We purchased an identity certificate for the ASA from GoDaddy and have installed both the identity certificate and the root CA cert on the ASA.  The question now is how to setup the Cisco VPN Client.  Do we need to purchase seperate certificates for each of the remote clients?  Will it work using the same certificate on several different clients?  Is there a way to do this without having to purchase third party certificates?

For IPsec however it is not required. You can have both ASA and user certificates provided by an internal CA (windows CA, openCA, ejbca, etc...)

There is a basic configuration example:
