OAuth2 Proxy for Single-Sign-On with Nginx

This application implements a generic OAuth2 client for easy integration of NGINX into an OAuth2-based Single-Sign-On system. It is bound to a single OAuth2 server (urls defined in config) and -- apart from a session cookie -- stateless. OAuth2 client id, secret and redirect URI are passed from the integrating NGINX to the proxy in HTTP headers.

See testapp for an example setup.
