As I have said a couple of times already, the user should not have to
login more than once.  If that were the case, then that would be a
problem with the IdP.  The generation of an assertion might require
login, but validation definitely shouldn't.

It's also possible that you already have a session open with your IdP.
 In that case, you wouldn't necessarily see a login flow at all.
