我正在通过/etc/fstab在 Centos 7 机器上安装 Windows 10 共享，如下所示：
//10.11.11.7/shared_folder /path/to/mount_point cifs user,rw,suid,uid=0,gid=1111,username=win_user,password=win_user,file_mode=0755,dir_mode=0777,vers=3.0 0 0
当我使用属于权限组 1111 的用户登录时，登录过程被中断，我被踢回登录屏幕。如果我使用 1111 组之外的用户登录，则登录成功（当然，安装的文件夹无法访问）。
如果我创建一个名为“mount_point_new”的新文件夹并相应地调整 fstab，一切正常，即：
//10.11.11.7/shared_folder /path/to/mount_point_new cifs user,rw,suid,uid=0,gid=1111,username=win_user,password=win_user,file_mode=0755,dir_mode=0777,vers=3.0 0 0
“mount_point”和“mount_point_new”都具有相同的预挂载权限。我真的很想使用原始名称（“mount_point”）作为路径在某些配置中使用。我不是专业管理员，而是单人家庭办公室设置，所以我真的很想了解问题并解决它，而不是通过使用新的挂载点名称来避免它。
以下是登录失败后/var/log/messages的片段：
