Subject: SAML 2.0 and Man in the Middle attacks



I am currently leading the technical part of a big European project (http://www.eid-stork.eu/) targeting federated identity between EU countries.

We are obviously looking at SAML, but we have a major concern, as it is not immune at all against MITM attacks.
Several countries are in favor of developing an alternative protocol (like TLS-Federation - ), but I would like to check with you if this problem was ever tackled.

Did you provide any work on this ?
Could this be solved by any way ?
How does it integrate with CardSpace ? Could such a combination solve the problem ?

Thank you
