The last several years have seen broad adoption of two different cross-domain authentication frameworks and their associated identity spaces. Higher Education worldwide, a growing number of business systems (especially cloud-based), and groups particularly concerned with security have adopted the SAML protocol and profiles and associated infrastructure (eg metadata describing participants). More recently, personal web use and a growing number of apps that are of interest to the higher ed community are using the OIDC/OAuth2 protocol and frameworks. Today, using these protocols requires two different identity spaces (identifiers, credentials). The growing use of OAuth2 to protect API endpoints by higher ed has increased the interest in bridging these spaces, and providing a single software package supporting multiple protocols. This is expected to provide better security, improved usability, and better interoperability in a multi-protocol world.
