Hello Perry,

i trust the IdP, but i do not trust the SP. For that i wanted the "bar SP" to talk to the IdP as well to verify that the asking user is authenticated.

Giving "foo SP" a definite access to "bar SP" is defective by design. if it becomes compromised one only need a user's id to access the user's data on "bar SP".
