That allows for this to be done, and because it's so totally impossible to even know where this user identity would come from or what such a NameID could look like, it's just not possible to even do more than say "ok, whatever, you can access everything but you have to do that".</p> <p style="margin: 10px 0 0 0">Strictly speaking this doesn't require any processing on the back side because the IdP-as-SP can't even know that any data it gets back would line up or match the value that was sent, but there should still be some kind of parallel feature to add a step where an injected function could actually block acceptance also.</p> </td>
