This a fairly complete implementation of OpenID Connect as specified in the OpenID Connect Core specification. And as a side effect a complete implementation of OAuth2.0 too. Please see the documentation to get started.
Cudos to Vladislav Mladenov and Christian Mainka both at Horst Görtz Institute for IT-Security, Ruhr-University Bochum, Germany for helping me making the implementation more secure.
