That is, for the record, not a reasonable constraint in a federated world.

The specific selection of the IdP can be driven in the SP based on a content setting applied via Apache or the RequestMap, by providing the entityID setting naming the IdP to use.

That does not prevent any given IdP's assertion from being accepted for login to any resource, if that the SP trusts it. It's assumed that you have authorization in place based on attributes.
