-Attributes
-~~~~~~~~~~
-
-.. attribute:: RemoteUserBackend.create_unknown_user

-    ``True`` or ``False``.  Determines whether or not a

-Methods
-~~~~~~~
-
-.. method:: RemoteUserBackend.authenticate(remote_user)
-
-    The username passed as ``remote_user`` is considered trusted. This method
-    simply returns the ``User`` object with the given username, creating a new
-    ``User`` object if :attr:`~RemoteUserBackend.create_unknown_user` is
-    ``True``.
-
-    Returns ``None`` if :attr:`~RemoteUserBackend.create_unknown_user` is
-    ``False`` and a ``User`` object with the given username is not found in the
-    database.
-
-.. method:: RemoteUserBackend.clean_username(username)
-
-   Performs any cleaning on the ``username`` (e.g. stripping LDAP DN
-   information) prior to using it to get or create a
-   :class:`~django.contrib.auth.models.User` object.  Returns the cleaned
-   username.
-
-.. method:: RemoteUserBackend.configure_user(user)
-
-   Configures a newly created user.  This method is called immediately after a
-   new user is created, and can be used to perform custom setup actions, such
-   as setting the user's groups based on attributes in an LDAP directory.
