Basic Authentication in Play! Framework (Scala)

Based on my previous post, a very simple implementation of http authentication based on basic access authentication.

This example retrieves the authentication data from the http request header. It uses flatMap as a way to idiomatically access and parse the "Authorization" key, if present. The constructs flatMap, map, foreach work very well in combination with scala Option, since the value None is always discarded.

Furthermore, this very simple example uses the org.apache.commons.codec to decode the base64 user:password value of the basic authentication. In this example, the password in not processed, and the user string is passed on to the for further processing using the chainedAction -> Action mechanism already explained in the previous post.
