Well, there's no procedure of any sort, that's out of scope really. If
people choose to deploy IdPs and lock them down, then there's not a lot
you can do about that but beg, which not a lot of people are going to
waste their time doing. There are simply classes of IdP deployments, some
that are designed for broad usage and some designed for only
Frankly, the biggest asset of the InCommon R&S concept is probably the
notion of tagging the *IdPs* that are willing to play ball. We haven't
stumbled on a clean way of addressing that in a more general capacity.
But for any given service that *has* to get certain IdPs to work, it
really needs to be part of a larger relationship.

something seems to be wrong with your metadata.

That's a bug related to logging of SAML errors returned by IdPs. Which
doesn't match with an IdP throwing an error about the endpoint, which
doesn't ever return anything to the SP.
