A user certificate is not required. If your Openssl library is configured correctly and your certificate bundles are installed properly it should neither be necessary to explicitly set up the ca certificate. The vpn gateway uses a DFN certificate which is issued below the root ca tree of the German Telekom, one of the CA's trusted by most browsers, the trusted-cert is the digest of the server's certificate which is subject to change every couple of years.
