Hi, I'm proud to announce the release of undertow-pac4j v1.1 (based on pac4j v1.8.5) for Undertow 1.3. It's now a full security library, easy and powerful, which supports authentication and authorization, but also application logout and advanced features like CSRF protection. It supports most authentication mechanisms: OAuth (Facebook, Twitter, Google, Yahoo...), CAS, HTTP (form, basic auth...), OpenID, SAML, Google App Engine, OpenID Connect, JWT, LDAP, RDBMS, MongoDB and Stormpath and authorization checks (role / permission, CSRF token...) Read the documentation: https://github.com/pac4j/undertow-pac4j And see the demo: https://github.com/pac4j/undertow-pac4j-demo Thanks. Best regards, Jérôme
