Ipsilon is a server and a toolkit to configure Apache-based Service Providers. The server is a pluggable selfcontained mod_wsgi application that provides federated SSO to web applications. User authentication is always performed against a separate Identity Management system (for example a FreeIPA server), and communication with application is done using a supported federation protocol.
The protocols supported out of the box are: SAML2, OpenID Connect, OAuth2, OpenID 2.0.
It is easy to drop in additional protocol plugins.
The current Ipsilon release is 3.0.2, released on 2022-06-23.
