我是 Linux 新手。我正尝试将 Ubuntu 16.04 服务器加入 Windows 域。我遇到了本文。我使用了一篇针对 14.04 的类似文章，几乎没有出现问题。
当我运行时，sudo apt install krb5-user samba sssd ntp我收到错误消息：
adduser: Warning: The home directory `/var/lib/sss' does not belong to the user you are currently creating.
Warning: found usr.sbin.sssd in /etc/apparmor.d/force-complain, forcing complain mode
Warning failed to create cache: usr.sbin.sssd
Job for sssd.service failed because the control process exited with error code. See "systemctl status sssd.service" and "journalctl -xe" for details.
sssd.service couldn't start.
我不知道为什么会发生这种情况。
