Higher Education has largely embraced federated identity management, which makes it really easy for people to collaborate across universities that belong to the the InCommon federation. But most campuses want to collaborate with people outside the federation, too, like research collaborators, incoming students, alumni, guest faculty, auditors, continuing education students, etc. It can be time-consuming and inefficient to create university identities for these external collaborators, and most of the collaborators already have an identity or two with a social provider like Google, LinkedIn, Facebook, or Twitter. Social-to-SAML gateways are an excellent way to extend university services to non-university collaborators at low cost. This presentation will describe some of the things to look out for when implementing social-to-SAML gateways, and demo a service built by Cirrus Identity that facilitates social-to-SAML integrations.
