How to secure Silverlight WCF Services using a custom Client cert validator mechanism
===

I have been using silverlight to develop a web application where i authenticate the user using client certifcates.

My question is how do i secure my WCF Services to only be called by users with a valid client certificate.

I have found many tutorials showing how to use username and password from silverlight to create a custom UserNamePasswordValidator. (http://blogs.infosupport.com/silverlight-3-securing-your-wcf-service-with-a-custom-username-and-password-authentication-mechanism/)

However i really need some help in securing my wcf services using a custom client certificate validation.  I'm not even sure if it is even possible.

Thanks in advance.
