Thanks for your very fast reply.
In this case, I want to use SAML only for simple AuthenticationStatements. I use them as endorsed supporting tokens. So for me it would be the best when a client gets a token and can use for every web-service on the server.
Problem is the WCF implementation of Microsoft which calls the STS for each web-service, means a generated WCF client requests for each service a token (AppliesTo in the request).
