我是 Ubuntu 的新用户。我希望我的 Ubuntu 桌面能够加入 Windows AD 域。当我尝试使用以下步骤加入 Active Directory 时SSSD 和 Active Directory来自 Ubuntu 文档。我遇到了 SSSD 服务启动问题
sudo systemctl start sssd.service
当我输入此命令时，出现错误响应：
Job for sssd.service failed because the control process exited with error code.
See "systemctl status sssd.service" and "journalctl -xe" for details.
这是我运行命令时得到的结果systemctl status sssd.service：
● sssd.service - System Security Services Daemon

有人能帮助我知道为什么会发生这种情况吗？
谢谢 ！
