使用WCF和自托管的Windows身份驗證

Question

我已經開發了一個非常簡單的主機和客戶端，我想用它來測試WCF客戶端是否可以將登錄Windows的用戶憑據傳遞給主機服務，而無需用戶重新輸入憑據或設置安全性。

我的主機配置如下所示：

<configuration>
  <system.serviceModel>
    <services>
      <service name="WCFTest.CalculatorService" behaviorConfiguration="WCFTest.CalculatorBehavior">
        <host>
          <baseAddresses>
            <add baseAddress = "http://localhost:8000/WCFTest/CalculatorService/" />
            <add baseAddress = "net.tcp://localhost:9000/WCFTest/CalculatorService/" />
          </baseAddresses>
        </host>
        <endpoint address ="basicHttpEP" binding="basicHttpBinding" contract="WCFTest.ICalculatorService" bindingConfiguration="basicHttpBindingConfig"/>
        <endpoint address ="netTcpEP" binding="netTcpBinding" contract="WCFTest.ICalculatorService"/>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>

      </service>
    </services>
    <bindings>
      <basicHttpBinding>
        <binding name="basicHttpBindingConfig">
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Windows" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="WCFTest.CalculatorBehavior">          
          <serviceAuthorization impersonateCallerForAllOperations="false"  principalPermissionMode="UseWindowsGroups" />
          <serviceCredentials >
            <windowsAuthentication allowAnonymousLogons="false" includeWindowsGroups="true" />
          </serviceCredentials>
          <serviceMetadata httpGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

我的客戶端配置如下所示：

<configuration>
    <configSections>
        <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >

        </sectionGroup>
    </configSections>

                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ICalculatorService"
                contract="CalcService.ICalculatorService" name="BasicHttpBinding_ICalculatorService" />

                contract="CalcService.ICalculatorService" name="NetTcpBinding_ICalculatorService">
            </endpoint>
        </client>
    </system.serviceModel>
    <userSettings>
        <WCFClient.Settings1>
            <setting name="Setting" serializeAs="String">
                <value>True</value>
            </setting>
        </WCFClient.Settings1>
    </userSettings>
</configuration>

我的客戶代碼是：

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Press enter to start");
        Console.ReadLine();

        CalcService.ICalculatorService httpCalcService = new CalcService.CalculatorServiceClient("BasicHttpBinding_ICalculatorService");
        Console.WriteLine(httpCalcService.AddValues(new int[] { 1, 2, 3 }).Value);
        Console.ReadLine();

        CalcService.ICalculatorService TcpCalcService = new CalcService.CalculatorServiceClient("NetTcpBinding_ICalculatorService");
        Console.WriteLine(httpCalcService.AddValues(new int[] { 5, 10, 15 }).Value);
        Console.ReadLine();
    }
}

如果我在PC上運行客戶端，這將很好地工作。 如果我在同事的PC上運行客戶端，則會在客戶端上獲得此異常堆棧：

未處理的異常：System.ServiceModel.Security.MessageSecurityException：使用客戶端身份驗證方案“協商”對HTTP請求進行了未授權的處理。 從服務器收到的身份驗證標頭是'Nootiate oX0we6ADCgEBonQEcm BwBgkqhkiG9xIBAgIDAH5hMF + gAwIBBaEDAgEepBEYDzIwMTAwMzExMTAzNjAzWqUFAgMEDFimAwIBKakGgXJJL1QQQ5K ---> System.Net.WebException：遠程服務器返回錯誤：（401）未授權。 ---> System.ComponentModel.Win32Exception：目標主體名稱在System.Net.NTAuthentication.GetOutgoingBlob（Byte [] entryBlob，Boolean throwOnError，SecurityStatus＆statusCode）處不正確

任何幫助表示贊賞，

謝謝，

在客戶端的配置中，您需要在'endpoint'元素內添加一個附加元素，以指定運行該服務的主體。 這是一個例子：

<identity>
      <servicePrincipalName value="user@mydomain.com" />
</identity>

在客戶端和主機之間建立通道時，這應允許進行正確的身份驗證。 如果該服務在其他帳戶下運行，則需要相應地調整該值（即，如果使用系統帳戶作為Windows服務運行，則類似於“ host / mymachine.mydomain.com”）。
