我正在设置一个教室环境，其中 Windows 2012 R2 Server 用作域控制器和文件服务器。所有客户端都将是 Kubuntu 14.04。我已经在服务器上设置了域和 NFS 共享。我可以在客户端计算机上手动安装共享，但我尝试将客户端配置为在用户登录时使用 pam_mount 自动安装共享。
在客户端计算机上，showmount 命令列出了共享。用户已加入域并在 AD 中可见。
我可以手动挂载共享，但是尽管遵循了许多在线教程，我似乎无法正确获取 pam_mount.config.xml 文件中字段的语法，我收到一条错误消息：
mount.nfs: an incorrect mount option was specified
我的 pam_mount.conf.xml 中的卷行：
<volume fstype="nfs" server="INSTRUCTOR.mydom.lan" path="/%(USER)" mountpoint="/home/%(USER)" user="*" options="workgroup=mydom.lan,uid=%(USER),dir_mode=0700,file_mode=0700,nosuid,nodev" />
我已经打开调试，以下是输出：

我的公共会话文件的内容：
#
# /etc/pam.d/common-session - session-related modules common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of modules that define tasks to be performed
# at the start and end of sessions of *any* kind (both interactive and
# non-interactive).
#
# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules. See
# pam-auth-update(8) for details.
# here are the per-package modules (the "Primary" block)
session [default=1] pam_permit.so
# here's the fallback if no module succeeds
session requisite pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
session required pam_permit.so
session required pam_mkhomedir.so skel=/etc/skel/ umask=0077
# The pam_umask module will set the umask according to the system default in
# /etc/login.defs and user settings, solving the problem of different
# umask settings with different shells, display managers, remote sessions etc.
# See "man pam_umask".
session optional pam_umask.so
# and here are more per-package modules (the "Additional" block)
session optional pam_mount.so
session required pam_unix.so
session [success=ok default=ignore] pam_lsass.so
session optional pam_systemd.so
session optional pam_ck_connector.so nox11
# end of pam-auth-update config
对于我做错的事情的任何建议，我都感激不尽。

据我所知，无论是workgroup还是file_mode 都不uid是 NFS 挂载的有效挂载选项。支持的挂载选项通常在系统手册中列出 man 5 nfs。
从卷定义中删除该选项，您的错误消息就会消失。
