从 sharepoint Web 部件访问 samba 共享时出现问题

Question

我正在使用 System.IO.File.Copy 将文件从本地 windows/sharepoint 服务器复制到 samba 共享。但我遇到了一个例外：

Logon failure: unknown user name or bad password.
:    at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
  at System.IO.File.InternalCopy(String sourceFileName, String destFileName, Boolean overwrite)
  at System.IO.File.Copy(String sourceFileName, String destFileName, Boolean overwrite)

我登录的用户确实有权访问该共享。 IE。我可以从本地共享点服务器手动将驱动器映射到它。

如果我还授予运行共享点的服务帐户访问共享的权限，则 System.IO.File.Copy 操作正常。

从 Samba 日志中，我发现 sharepoint/windows 没有将我的用户名传递给 Samba。请参阅下面的 FAILED 日志下的： (check_ntlm_password: Checking password for unmapped user [][]@[FODV-SHRPT-01] )。

（我相信这些是 samba 日志的相关部分）第一个成功的服务帐户具有提升的权限，第二个失败的登录：

如果有人能对此有所了解，我将不胜感激。 成功：

Double hop issue?否则，这是您的 SharePoint 代码未在用户上下文中运行的问题。

SharePoint 将模拟用户，除非您在 SPSecurity.RunWithElevatedPrivileges 委托中。
