Shibboleth IDP

Go back

Shibboleth is a standards-based, freely available open-source software package for Web single sign-on across or within organizational boundaries. It allows sites to make informed authorization decisions for individual access of protected online resources in a privacy-preserving manner. It was developed by the Internet 2 project using the OpenSAML open-source implementation of SAML 2.0. It is being used by at least one participant in GFIPM.

The GFIPM federation extends the authorization functions to include privilege management for the justice community and partner organizations with a standards-based approach for implementing federated identity. Note that Shibboleth has separate components that act as an IDP and an SP.

Several components of the GFIPM Reference Federation are implemented using Shibboleth, including the Reference IDP, the Reference SP, and the production CISA IDP and SP.

Existing federation members and technical support staff have extensive implementation experience with Shibboleth. The GFIPM reference IDP and SP use Shibboleth.
