This could be an overshoot but you can have two portals, use one as
the default and the second one as a fallback. I think the code will be
a little bit cleaner at the checker/realm side at the price of a little
bit of complexity at the login side:

	portal1.login(credentials, None).addErrback(lambda _:
		portal2.login(credentials, peer)).addCallbacks(...)

But I don't know if it is worth the candle.
