Ошибка промежуточного ПО пользовательской аутентификации Django

Последуя точному примеру из документации, я получаю следующую ошибку. У меня есть необходимый файл на месте по мере необходимости.

https://docs.djangoproject.com/en/4.1/topics/auth/customizing/#writing-an-authentication-backend

 61, in load_middleware
    mw_instance = middleware(adapted_handler)
TypeError: SettingsBackend() takes no arguments

settings.py содержит следующее.

MIDDLEWARE = [
   ...
    'myweb.middleware.example_authentication.SettingsBackend'
]

Здесь SettingsBackend

from django.conf import settings
from django.contrib.auth.backends import BaseBackend
from django.contrib.auth.hashers import check_password
from django.contrib.auth.models import User

class SettingsBackend(BaseBackend):
    """
    Authenticate against the settings ADMIN_LOGIN and ADMIN_PASSWORD.

    Use the login name and a hash of the password. For example:

    ADMIN_LOGIN = 'admin'
    ADMIN_PASSWORD = 'pbkdf2_sha256$30000$Vo0VlMnkR4Bk$qEvtdyZRWTcOsCnI/oQ7fVOu1XAURIZYoOZ3iq8Dr4M='
    """

    def authenticate(self, request, username=None, password=None):
        login_valid = (settings.ADMIN_LOGIN == username)
        pwd_valid = check_password(password, settings.ADMIN_PASSWORD)
        if login_valid and pwd_valid:
            try:
                user = User.objects.get(username=username)
            except User.DoesNotExist:
                # Create a new user. There's no need to set a password
                # because only the password from settings.py is checked.
                user = User(username=username)
                user.is_staff = True
                user.is_superuser = True
