Using SAML token as a supporting token

Question

Hello,

I am using the federation binding with an STS. I have turned off secure conversation using the information in the article http://msdn.microsoft.com/en-us/library/ms731827.aspx.

However, with this off, WCF is now using the SAML token as the protection token. But I would like to use the SAML token as a supporting token, and use something else ie X509 as the protection token.

How can I do this?

Thanks
