[Roger Tawa OOO till Jul 10th, 2013/05/06 15:46:39]

I think |untrusted_confirmation_required| should be set to false here, much like
in the case above.  Previous, we did not display the confirmation because the
user will see the advanced config dialog, and has a chance to abort the connect
before it actually happens.

[Andrew T Wilson (Slow), 2013/05/06 17:00:13]

I'm slightly nervous about this since the user isn't actually shown the email
address he's signed in with if he just goes to the advanced config dialog -
he'll be tempted to just click OK to dismiss the dialog, in which case the
signin will complete. In the untrusted/SAML case, I'd rather prompt him.

In any case, if this isn't OK/is too cumbersome, let's drive a separate CL.
