Django Admin - 无法使用超级用户登录

Question

关于这个主题有几个问题，但没有一个问题解决了我的挑战。我无法使用正确的用户名和密码登录Django Admin。

settings.py：

import os
from django.core.exceptions import ImproperlyConfigured

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

def get_env_variable(variable_name):
    try:
        return os.environ[variable_name]
    except KeyError:
        error_msg = 'Set the {} environment variable'.format(variable_name)
        raise ImproperlyConfigured(error_msg)

我尝试打开和关闭各种安全设置。我可以访问数据库，超级用户存在并且是工作人员。当我尝试登录时，数据库表显示当时登录的超级用户，但浏览器不会超出启动页面并且说用户名/密码不正确。其他工作人员（即非超级用户）可以登录。我认为问题可能在于我在模型后端使用RemoteUser后端这一事实，但我不确定。

为什么我的超级用户无法登录？
