从sharepoint web部件访问samba共享时出现问题

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。但我有个例外：

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)

我登录的用户确实可以访问该共享。即，我可以从本地sharepoint服务器手动将驱动器映射到它

如果我还提供sharepoint运行共享访问权限时使用的服务帐户，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。请参阅以下失败日志下的：（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）第一个成功的部分用于具有提升权限的服务帐户，第二个失败的部分用于我的登录：

如果有人能解释一下，我会非常感激的。 成功的：
