This document discusses identity and access management using Shibboleth and Edugate. It describes identity providers (IP) that authenticate users and service providers (SP) that authorize access. Edugate establishes trust between IP and SP using SAML protocol. The document outlines library use cases for integrating systems like Summon, repositories, catalogs and reference managers with Edugate single sign-on. It also provides guidance on getting publishers, Ezproxy, Millennium and Summon to participate in Edugate federated authentication.
