Hi all

With that broad variety of browsers used and really old versions that are still out there, it's almost impossible to have a solution for everyone. I'm fine if there's a solution that does not hurt old versions and the latest browsers support.

As far as the login page in an iframe: If you do that the URL of
the IdP doesn't show up anywhere, does it? How would the user know
That's right. In that case, the user can't verify the login form was sent from his IdP.

this is the IdP's page and not a fake? Why would someone do that?
If an iframe is used to integrate the login form into a page which is sent from another server, the user should have good reasons to trust that server. Some institutions may chose to use iframes for whatever reason, probably for better usability. Are there any who do this on this list?

Anyone whose infrastructure would be affected by using the x-frame-options header?
