Good Identity Federation Practice

A ratings guide for identity providers, service providers, and federation operators.


This document brings a “good practice” approach to identity federation in research and education. In short, it answers two questions:

  • How can a federation participant tell that their identity provider or service provider works properly?

  • How can a federation operator ensure that participants can interoperate while simultaneously (1) protecting the integrity of the trust fabric and (2) promoting useful change?

Validating an identity provider or service provider deployment presents a significant roadblock for people who have never used federated identities before. Current good practice involves an overwhelming variety of standards, expectations, entity categories, frameworks, profiles, and more. There exists no single, comprehensive resource for operational guidance and integration testing. What documentation or test resources exist are difficult to find even for experienced professionals, are typically restricted to federation members, and are focused almost exclusively on identity providers. While the decentralized nature of identity federation allows it to scale far beyond current commercial offerings, that same decentralization makes enacting meaningful change to participant or federation operations seemingly impossible. A scorecard would be a powerful tool for change.
