How does GIdP work?

GIdP is a simple eduGAIN-compatible Identity Provider system, where user identities and attributes are registered. GÉANT2 services across the pan-European backbone and the national networks can then redirect users to GIdP for authentication and authorisation.

IdP: Identity Provider.
Shibboleth: an AA technology supported by eduGAIN.
SimplesamplPHP: an award-winning application that deals with authentication.
H-BE: Home Bridging Element that connects an IdP to eduGAIN.
R-BE: Remote Bridging Element that connects a resource to eduGAIN.
