Since the 2.0 release of LemonLDAP::NG, we worked a lot on OAuth2 and OpenID Connect and the latest versions of the software can now be used to authenticate mobile applications, protect API and Webservices. For example, LemonLDAP::NG supports refresh tokens, for online and offline mode, and some OAuth2 specific endpoints like the introspection endpoint. In this presentation you will discover these new features and learn how to use them for your applications. Presentation by Clément Oudot, Worteks.
