Internet2 and Shibboleth
Shibboleth is a project within the Internet2 higher-education consortium to develop technical and policy frameworks and an open software system for the sharing of online resources among researchers, professors, and students.
Shibboleth and SAML
Shibboleth profiled SAML for its particular requirements and also built privacy management into its architecture. Shibboleth's input was fed back into SAML V2.0, and new work at Shibboleth is anticipated to be built on the SAML V2.0 OASIS Standard.
