I have recently finished creating a STS setup and need to expose some WCF service methods on the STS's themselves. So far the login sends a token to the claims provider, the claims provider sets all the clams and then hands the user back down to the front end so that's working fine. I need to implement some WCF functions that need to check that the user has a valid token to trigger the method. I have looked into it and have tried configuring WSFederationHttpBind with little success. It seems to ask the client for a certificate via "Windows cardspace" for some reason and I can't find a way to assign the already produced token with the WCF call from the client. Any pointers in the right direction would be great I've been racking my brains all day and clearly not searching for the right thing!
P.S The STS uses WIF to create/assign the tokens
