Shibboleth Authentication

Shibboleth is a free, open-source web single sign-on system with rich attribute-exchange based on open standards, principally SAML. It is a federated system, supporting secure access to resources across security domains. Information about a user is sent from a home identity provider (IdP) to a service provider (SP) which prepares the information for protection of sensitive content and use by applications. So-called federations, while not a purely technical construct, can often be used to help providers trust each other in a scalable way.

Once you have configured your web server to act as an SP you can enable shibboleth for user authentication be setting adminAuthenticationClass to Shibboleth.
