If request.user is not authenticated, then this middleware attempts to authenticate the username passed in the ``REMOTE_USER`` request header. If authentication is successful, the user is automatically logged in to persist the user in the session. The header used is configurable and defaults to ``REMOTE_USER``. Subclass this class and change the ``header`` attribute if you need to use a different header.

Useful for setups when the external authentication via ``REMOTE_USER`` is only expected to happen on some "logon" URL and the rest of the application wants to use Django's authentication mechanism.
