Question

我创建了一个 IIS -hosted WCF OData-service 两个从 MS-SQL数据库发布表。当我尝试从自定义 C＃项目访问该服务时，我收到一条错误消息，指出'NT-AUTHORITY \ ANONYMOUS'无法访问数据库。

IIS 配置为模拟用户，当我从浏览器请求相同的网址时，我会获取数据，所以我怀疑我自己的 C＃ - 应用程序正在执行请求，由于某种原因，用户没有正确模拟。

以下是事实：

IIS

ASP-Impersonation 。
使用 NTLM进行Windows身份验证 -only是唯一激活的身份验证方法。
应用程序池正在运行集成（v4.0），validateIntegratedModeConfiguration已关闭。
如上所述，我可以通过浏览器访问所有数据。
我可以从我的客户端应用程序访问OData元数据，因此身份验证基本上可以正常工作。

以下是我的客户端代码片段：

var serviceContextContext = new DataServiceContext(_url);
_serviceContextContext.IgnoreMissingProperties = true;
_serviceContextContext.IgnoreResourceNotFoundException = true;
_serviceContextContext.SendingRequest += DataServiceContextContextSendingRequest;

// Here is where I get an internal server error
var response = _serviceContextContext.Execute<ODataEntity>(entitySetRequestUri);

private void DataServiceContextContextSendingRequest(object sender, SendingRequestEventArgs e)
{
    var request = (HttpWebRequest)e.Request;
    request.Credentials = new NetworkCredential(_user, _password,_domain);
}

这是小提琴手给我的东西：

在回复中，我收到以下错误消息：

Cannot open database "TEST" requested by the login. The login failed. Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'

所以我得出结论，我的请求与浏览器请求有所不同，这阻止了模拟正常工作。

我真的很感激任何提示。
