AARC-G049 A specification for IdP hinting

This document defines a generic browser-based protocol for conveying – to services – hints about the IdPs or IdP-SP-proxies that should be used for authenticating the principal. This protocol, colloquially referred to as Identity Provider (IdP) hinting, can greatly simplify the discovery process for the end-user, by either narrowing down the number of possible/IdPs to choose from or by making the actual selection process fully transparent.
