The existing rules for realm are basically same-origin policy.  That
doesn't actually work for any of the delegated auth solutions that
OAuth2 is based on, and is meant to replace.  Telling people to use
realm is terrible, no-good, very-bad advice.

As far as I can tell, the only practical guidance we can give
developers is "follow the service provider documentation."
