Simple example of a Play app that uses OpenID to handle user authentication.  The first time a new OpenID is authenticated, a new User is created for it.  Subsequent auths reuse that User.

I have successfully authenticated with myopenid.com and flickr.com OpenID providers.  The wordpress.com OpenID provider does not work with this app, not sure why.  I have not tried any other OpenID providers.

Note that this project runs on port 9090 (the default port 9000 was conflicting with something in Eclipse).

To run this app just clone this repo, execute "play run" and visit http://localhost:9090.
