This document summarizes a presentation about implementing Shibboleth single sign-on (SSO) with Drupal. It introduces Justin Ludwig and his company BioRAFT, which uses Drupal and Shibboleth SSO for its lab safety compliance software. It then explains what Shibboleth is, how it implements SSO via SAML and the identity provider/service provider model, and how to install, configure, and integrate Shibboleth with Drupal using the Shibboleth authentication module. Resources for learning more about Shibboleth, SAML, and SSO are also provided.
