Forced reauthentication

[David Bantz]

It doesn’t seem the first SP session really ended.  I see that you state "the SP logs a new session” but you don’t provide the log entry for that, and generally, merely closing the active browser tab does not end the SP session - not in my experience anyway.  So opening a new tab/window in the same browser session just continues with the existing session.  That of course does not require re-authentication.

If you want to test the re-authentication required after 5 seconds, you’ll need to destroy the SP session cookie.

I have a new SP I’ve been asked to introduce to the environment with the requirement that this SP force re-authentication each time it is used.  I realize this goes against SSO in general but it is still a requirement I need to try and fill.
