使用 samba 2:4.7.6，基于 Ubuntu 18.04.3 LTS 的 Lubuntu 发行版
枚举共享时有没有办法强制 samba 请求有效凭据？
问题：Windows 10 版本 1903 缓存会话凭据。EnumShares2浏览 SMB 服务器的共享时，它会使用匿名凭据枚举共享 ( )，这些凭据会被缓存。随后尝试连接到需要身份验证的共享失败并显示以下消息：
不允许同一用户使用多个用户名与服务器或共享资源建立多个连接。断开与服务器或共享资源的所有先前连接，然后重试。
在 Windows 10 1903 中，似乎没有任何方法可以强制 Windows 在不重新启动机器的情况下释放匿名会话。
枚举远程 Windows 计算机上的共享时不会出现此问题，因为自 Windows 1703（Server 2016？，不确定）以来已禁用共享的匿名浏览。
实际上，除非可以说服 samba 不使用匿名凭据枚举共享，否则 samba 共享几乎 100% 的时间都无法在窗口 10 上访问，因为用户不太可能在没有首先浏览服务器共享的情况下连接到共享。
/var/log/samba 日志文件中没有明显的错误。
@smbgroup 只包含一个用户“smb”，它是专门为访问共享而创建的。
我的 smb.conf 如下：
