Authentication ASP.NET, SilverLight, WCF and Forms - How to configure endpoints?

Question

I have this existing environment:

1) ASP.NET 3.5 web application

2) forms authentication using SqlMembershipProvider

I need to add the following:

1) a Silverlight graphic object embedded in a web page.

2) WCF service to be used:

 a) the Silverlight component embedded in an authenticated 
       web page, as mentioned above

 b) server-based WCF clients with certificate based authentication

My question is: what is the easiest / best way to configure WCF endpoints for a Silverlight object for authentication in a WCF service using the security context of an already registered user (through the page hosting the Silverlight object) without reusing the username / password?
