This project cas-pac4j-oauth-demo has been created to test the OAuth/OpendID/CAS support in CAS server version >= 4.0.0. It’s composed of two modules :
- the cas-pac4j-oauth-client-demo module is a CAS server which uses the OAuth/OpenID/CAS client mode : it acts as a client to delegate authentication to Facebook, Twitter… : https://wiki.jasig.org/display/CASUM/OAuth+client+support+for+CAS+server+version+%3E%3D+4.0.0
- the cas-pac4j-oauth-server-demo module is a CAS server which uses the OAuth server mode : it plays the role of an OAuth server : https://wiki.jasig.org/display/CASUM/OAuth+server+support.

To start quickly, build the project :

cd cas-pac4j-oauth-demo
mvn clean install

cd cas-pac4j-oauth-client-demo
mvn jetty:run

To test,
- call the https://localhost:8080/cas url and click on “Authenticate with …” (at CAS server in OAuth client mode)
- authenticate at your favorite provider (Facebook, Twitter…) or at the OAuth wrapped CAS server (same password as login, url : https://localhost:8080/cas2)
- be redirected to the first CAS server, being successfully authenticated.

You can also deploy manually these two web applications in your favorite web applications server :
- cas-pac4j-oauth-client-demo on https://localhost:8080/cas
- cas-pac4j-oauth-server-demo on https://localhost:8080/cas2
