How to log audit message when client certificate is invalid or expired.

Mar 17, 2008 at 4:36 PM
Hello,

I am trying to implement the functionality to log an ATNA message when a client certificate is invalid or expired. I know how to validate a server certificate from the client by adding a handler, but I have no idea how to validate incoming client certificates at the server side.

Is there a way to retrieve the client certificate before transactions are performed?

Thanks,

Harold
