我一直在寻找到底出了什么问题，但就是搞不清楚。关于在 Ubuntu 上使用 samba，我还有很多不明白的地方，所以如果有什么地方看起来不太对劲，我很抱歉。
在我更新我的 ubuntu 服务器之前，共享正常，教师帐户能够进行身份验证，但是当我更新时，它停止工作。
我正在使用 Ubuntu 服务器：分销商 ID：Ubuntu 描述：Ubuntu 15.10 发行版：15.10 代号：wily
和 samba：版本 4.1.17-Ubuntu
当我尝试从 Windows 计算机映射网络驱动器时（本例中为 Windows 10，也使用 Windows 7 获得类似结果），我收到以下日志结果/var/logs/samba/log.（Windows 的 ip 地址）：
check_ntlm_password: Authentication for user [teacher] -> [teacher] FAILED with error NT_STATUS_NO_SUCH_USER
[2016/01/06 14:00:51.944975, 3] ../source3/auth/auth_util.c:1593(do_map_to_guest_server_info)
No such user teacher [HeritageFileServer] - using guest account
从 Windows 机器上，我以 HeritageFileServer\teacher 身份登录，我还尝试过 HERITAGEFILESERVER\teacher，以及 teacher，过去，第一个运行良好。
如果我输入 sudo编辑 -L -v据我了解，它应该列出我的 samba 用户，我得到了以下信息：

显然teacher是存在的，而且密码很简单，所以我确定我没有弄错，我甚至使用smbpasswd重置了密码以确保无误。
我最终将重要文件夹设置为允许访客帐户，以便教师可以访问驱动器，同时我试图让日志显示它已成功通过身份验证。这是我的 smb.conf 文件（我将 share 和 Share 作为现在向访客开放的原始文件夹，而 Shared 是我的测试文件夹，我正在尝试使其与身份验证配合使用）：

有人知道什么问题吗？
答案1
打开终端并尝试以下操作：
sudo smbpasswd -a < username>
这里，< username> 是您的用户名。现在，您将被提示设置并重新输入新密码。
然后，重新启动 smb 服务：
sudo service smbd restart
现在，尝试以通常的方式打开共享位置。输入用户名和刚刚设置的新密码。
您现在就可以登录了。
