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.
