Hi Kings,

Did you test client-based certificate authentication, or server certificate verification?
The last the ASA can do, as the ASA can have a dns-server configured, so it can verify the subject of the certificate against the hostname you're trying to connect to. (most common usage is that the client only validates that it is connecting to the specified hostname and that the certificate belonging to that hostname is valid).

About the client-based certificate, it could be that the ASA is using his certificate (if it's also from the same domain CA) as client authentication and not the certificate of your browser. You don't see that much client-based certificate authentication (WAAS Central manager and MS BITS use it), but for browsers with end users, haven't come across them that often

Hi all

When you access any site using HTTPS in the webvpn portal, the remote user is never prompted with the certificate. The ASA does the certificate validation.
How does the ASA do the cert validation? It doesn't have the certificate in it's database then how come it is validating the cert?



With regards
Kings
