Asp.net SSRS Web服务访问异常-401未经授权方案'；Ntlm&x27；

我已经为下面的.NETFramework4.0异常花费了一天的时间。我在网上研究过解决方案，但还没有找到一个可行的。 请提前帮助和感谢

我的asp.net web应用程序在本地PC环境中运行正常，该环境同时具有IIS 8.0和本地SQL Server 2012实例，但 当我将其部署到同时具有IIS 8.0和SQL server 2012实例的web服务器时，异常会出现

例外情况：

详情/我的故事：

我有一个asp.net web表单应用程序，该应用程序具有对SQL Server 2012 Reporting service的SOAP web服务的web引用并使用该服务（请参阅）。 我的名为“MyAspNetSolution”的asp.net web表单解决方案是使用VS 2012/.net framework 4.5和本地企业版SQL Server 2012开发的。该解决方案包含一个web表单应用程序项目 ，以及其他自定义类库项目。其中一个类库项目是名为“MyAspNetSolution.Services”的类库项目，它具有对的web引用 并使用SSRS SOAP web服务，如：

...
using MyAspNetSolution.Services.ReportService2010;
using System.Net;
...

namespace MyAspNetSolution.Services
{
    public class ReportServerInfoService
    {
            public CatalogItem[] ListReportCollection(string itemPath, bool recursive)
            {
            CatalogItem[] reportCollection = {};

            try
            {
                ReportService2010.ReportingService2010SoapClient client = new ReportService2010.ReportingService2010SoapClient();
                client.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
                client.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;

                client.Open();
                TrustedUserHeader t = new TrustedUserHeader();

                try
                {
                    // I need to list of children of a specified folder.
                    client.ListChildren(t, itemPath, recursive, out reportCollection); // see http://msdn.microsoft.com/en-us/library/reportservice2010.reportingservice2010.listchildren.aspx
                }
                catch (SoapException ex)
                {
                    _logger.Error("ReportServerManagementService--" + ex);
                }
            }
            catch (SoapException ex)
            {
                _logger.Error("ReportServerManagementService--" + ex);
            }

            return reportCollection;
           }
    }
}

在我的web应用程序项目web.config中，SQL Server 2012 Reporting service的SOAP web服务的端点、绑定和其他部分如下所示：

...
 <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="ReportingService2010Soap">
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Ntlm"></transport>
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://my-pc-network-domain-or-server-domain/ReportServer_SQL2012/ReportService2010.asmx" binding="basicHttpBinding" bindingConfiguration="ReportingService2010Soap" contract="ReportService2010.ReportingService2010Soap" name="ReportingService2010Soap"/>
    </client>
  </system.serviceModel>
...  

。。。
...  

p/S:

我还研究了以下线程（用于SharePoint客户端开发），代码与我正在开发的（用于SSRS客户端开发）相同，但在我的本地PC环境中工作，而不是在web服务器上

或其他资源：

您应该尝试NetworkCredentials并将其传递给客户端。如果仍然出现错误，请将其放在wcf配置文件中：

<identity>
    <servicePrincipalName value=""/>
</identity>

谢谢

将此添加为endpoint元素的子元素为我解决了错误。非常感谢。
