我正在尝试通过Web界面（ASP.NET / C＃）运行powershell命令，以便在Exchange 2007上创建邮箱/等。当我使用Visual Studio（Cassini）运行页面时，页面正确加载。但是，当我在IIS（v5.1）上运行它时，我收到错误“未知用户名或密码错误”。我注意到的最大问题是Powershell以ASPNET而不是我的Active Directory帐户登录。如何强制我的Powershell会话使用其他Active Directory帐户进行身份验证？
基本上，我到目前为止的脚本看起来像这样：
RunspaceConfiguration rc = RunspaceConfiguration.Create();
PSSnapInException snapEx = null;
rc.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out snapEx);
Runspace runspace = RunspaceFactory.CreateRunspace(rc);
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
using (pipeline)
{
pipeline.Commands.AddScript("Get-Mailbox -identity 'user.name'");
pipeline.Commands.Add("Out-String");
Collection<PSObject> results = pipeline.Invoke();
if (pipeline.Error != null && pipeline.Error.Count > 0)
{
foreach (object item in pipeline.Error.ReadToEnd())
resultString += "Error: " + item.ToString() + "\n";
}
runspace.Close();
foreach (PSObject obj in results)
resultString += obj.ToString();
}
return resultString;

在ASP.NET应用中，您需要使用正确的权限模拟有效的AD帐户：
答案 2 :(得分：1)
Exchange 2007不允许您出于安全原因冒充用户。这意味着（目前）无法通过模拟用户来创建邮箱。为了解决这个问题，我创建了一个在AD用户下运行的Web服务，该服务具有创建电子邮件帐户等的权限。然后，您可以访问此Web服务以访问powershell。请记住添加必要的安全性，因为这可能是一个巨大的安全漏洞。
