The IDentity Provider Open (IDPOPEN) is a SAML standard based service powered by Shibboleth. IDPOPEN is jointly managed by the Division of Catania of the Italian National Institute of Nuclear Physics and by the Department of Physics and Astronomy of the University of Catania. The service is hosted at GARR, the Italian National Research and Education Network. IDPOPEN allows people not enrolled in any campus' or organisation's Identity Provider to validate their identities when they sign in on web pages and Science Gateways that require user authentication.

IDPOPEN is the "catch-all" Identity Provider of the Grid IDentity Pool (GrIDP) federation and currently authenticates the users of several Service Providers
