我有一个新安装的 Kubuntu 18.04.1，通过sssd公司的 Microsoft Active Directory 进行用户身份验证。

每个用户都有一个 Samba 共享//fileserver6/$USER，我想在登录时挂载它。

我设法pam_mount配置为在用户登录时挂载共享，它工作正常......直到我退出 KDE，发现 sddm-greeter 不起作用！

没有登录提示，只有一个带有鼠标指针的黑屏。在下面pam_mount.conf.xml，我可以注释掉<volume>标签，然后通过 登录sddm，然后我可以取消注释并登录到终端会话，目录会自动挂载。但我不能两者兼得！

如果无法解决问题，我会很乐意安装另一个显示管理器（如果它有效）（lightdm甚至不会让我选择用户）。[ETA：lxdm确实有效]
