Shibboleth is a standards-based, open source software package used for implementing federated identity management and single sign-on based on the Security Assertion Markup Language (SAML). Using Shibboleth, organizations and enterprises needing to support a variety of users and applications can simplify the management of identity and permissions — while still preserving privacy.
Shibboleth is the leading SAML implementation used in higher education institutions around the world. Since 2003, hundreds of universities have secured access controls with Shibboleth.
