Authentication (Shibboleth)

Shibboleth is an Internet2 consortium project that acts as an intermediary between Shibboleth participants, enabling access to another (participating) institution's resources. You prove your identity to Shibboleth, and Shibboleth vouches for you with the other participant. 

Shibboleth is an open source software package that implements the SAML and CAS protocols and provides federated identity-based authentication services for web applications. Shibboleth provides single sign-on authentication services for UVM students, staff, and faculty to access resources at partner institutions without needing to create separate, local usernames and passwords for each one.

The University of Vermont is a member of the InCommon Federation, which has hundreds of participating institutions that implement similar SAML-based identity and service providers. Many of our peer universities as well as academic research resources also belong to InCommon (see the full list). Members of these participating institutions can leverage Shibboleth to provide authenticated access to web applications for all InCommon members with minimal setup and coordination.
