您好，我们正在运行集成了 Microsoft Active Directory 的 Samba 服务器 4.6.2。将 CentOS 7.3 升级到 7.4 版后，我们的 Samba 服务器开始抛出错误。有些用户无法将文件从桌面复制到服务器。
Samba 崩溃并出现核心转储，重启后，半个小时内一切都运行正常，然后 Samba 又开始记录错误。即使重启服务器后，Samba 也开始抛出错误。我读过操作方法部分，但这里只提供了基本的故障排除步骤，没有提供任何与此类似严重错误相关的信息。
我们使用的是 CentOS 7.4，最新内核版本为 3.10.0-693.2.2.el7.x86_64。我们的文件服务器有 16GB 内存和 4 个 CPU 核心。我很乐意为您提供任何帮助。
这是我的日志文件（/var/log/messages）：

答案1
请参阅我的回答： CentOS 7.4/Samba 4.6.2 升级后 Windows PC 被要求输入密码吗？
解决方案是在 smb.conf 的全局部分中添加：
ntlm auth = yes
这可能与您的问题有关。NTLMv1 与 NTLMv2 之间存在问题，Samba 4.6.2 发行说明中提到了这一点。
