Centrify samba: lib/util.c:1117(smb_panic) (使用Centrify速递)

Question

Samba正在以某种方式工作，但是有些进程崩溃了。只有当一些(或一个) Windows客户端访问GPO推出的网络磁盘时，才会出现这样的接缝。至少有一个w7客户端无法通过网络磁盘访问服务器。当用户尝试smb进程时，/var/log/samba/log.smbd中的以下ocoure崩溃：

我对DNS有点怀疑，因为windows客户端不能通过dns名称访问samba (但是服务器响应例如。在dns名称上进行ping操作，对于带有dns的mac客户端来说，nettatalk工作得很好。我已经将gpo更改为使用IP从samba服务器挂载网络驱动器，而不是dns，它对大多数客户端都很好。我已经卸载了使samba崩溃的客户机上的所有驱动器，并在/force客户机上运行gpupdate it.The从AD2008R2服务器获得IP，并且我检查了客户机上的DNS是正确的。

注意:域名是"opusark.local“。我收到了一个警告，当安装centrify关于结束“本地”是不擅长的，应该被避免。这有什么关系吗？

有关于如何排除此错误的线索吗？

用centrify使能的ssh登录到服务器的速度很慢，并不是所有的计算机都能工作。

坠机报告已经停止了。这可能是因为当客户端试图通过dns名称访问它们时，smbd进程崩溃了(由于某种原因，这不起作用)。
