Feide and Shibboleth
Feide and Shibboleth federations are based on the same concepts, but Shibboleth federations are somewhat different from Feide. In Shibboleth, it is common to have a mesh of IdPs and SPs, where each service that wants to integrate with a new institution must talk to the different organizations that operate IdPs.
Feide operates one central IdP. A service integrates once with this central IdP, and Feide adjusts access according to the service provider’s and home organization’s requests.
If your service already is integrated with a Shibboleth federation, you can easily integrate with Feide (or the other way around) if the following is in place:
Feide uses the SAML 2.0 protocol. You need to ensure that your service supports SAML 2.0, older versions are not compatible with Feide.
Feide requires the use of HTTPS.
Feide encourages single logout support.
