LDAP 和 NFS 在 KDE 和 SSH 上运行良好，用户可以毫无问题地登录。但只有 LDAP 用户不能直接或通过 NX 客户端登录 GNOME 桌面。
当直接在服务器上登录时，它会显示此错误：
Xsession: Login for is disabled
通过 NX 客户端登录时，它显示它已成功通过身份验证，然后弹出以下消息：
Could not connect to session bus: Failed to connect to socket /tmp/dbus-0frstajyNE: Connection refused
我关闭了这个弹出窗口，又出现了一个：
Could not acquire name on session bus
