interop with ADFS 2

Thanks for the feedback. Fortunately I'm not the one using ADFS. I just
run the IdP that they need to connect to. It's just interesting to me that
ADFS acting as an SP will refuse to send the browser to an HTTP only IdP
endpoint. I can see them requiring SSL on their side, since the person
running the ADFS site would have that level of control, but requiring the
partner IdP to use it is just a bug.

While I would like to run SSL for my IdP's (and always offer it as a
choice to my customers), the fact is that they are more concerned with
their end users calling them about the security warning pop-ups when they
would leave the SSL protected IdP for the non-SSL protected SP. That's
just the majority use case in the real estate MLS world.
