使用WCF和自我托管的Windows身份验证

Question

我开发了一个非常简单的主机和客户端，我想用它来测试WCF客户端是否可以将登录的Windows用户凭据传递给主机服务要求用户重新输入他们的凭证或设置安全性。

我的主机配置是这样的：

<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> 

我的客户端配置是这样的：

<configuration> 
    <configSections> 
     <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" > 
      <section name="WCFClient.Settings1" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> 
     </sectionGroup> 
    </configSections> 
    <system.serviceModel> 
     <bindings> 
      <basicHttpBinding> 
       <binding name="BasicHttpBinding_ICalculatorService" closeTimeout="00:01:00" 
        openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 
        allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 
        maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 
        messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 
        useDefaultWebProxy="true"> 
        <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 
         maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 
        <security mode="TransportCredentialOnly"> 
         <transport clientCredentialType="Windows" proxyCredentialType="None" 
          realm="" /> 
         <message clientCredentialType="UserName" algorithmSuite="Default" /> 
        </security> 
       </binding> 
      </basicHttpBinding> 
      <netTcpBinding> 
       <binding name="NetTcpBinding_ICalculatorService" closeTimeout="00:01:00" 
        openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 
        transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" 
        hostNameComparisonMode="StrongWildcard" listenBacklog="10" 
        maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10" 
        maxReceivedMessageSize="65536"> 
        <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 
         maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 
        <reliableSession ordered="true" inactivityTimeout="00:10:00" 
         enabled="false" /> 
        <security mode="Transport"> 
         <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign" /> 
         <message clientCredentialType="Windows" /> 
        </security> 
       </binding> 
      </netTcpBinding> 
     </bindings> 
     <client> 
      <endpoint address="http://ldndwm286380:8000/WCFTest/CalculatorService/basicHttpEP" 
       binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ICalculatorService" 
       contract="CalcService.ICalculatorService" name="BasicHttpBinding_ICalculatorService" /> 
      <endpoint address="net.tcp://ldndwm286380:9000/WCFTest/CalculatorService/netTcpEP" 
       binding="netTcpBinding" bindingConfiguration="NetTcpBinding_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> 

我的客户端代码：

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(); 
    } 
} 

，如果我跑这工作正常客户端在我的电脑上。如果我同事的PC上运行的客户端我在客户端上此异常堆栈：

Unhandled Exception: System.ServiceModel.Security.MessageSecurityException: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate oX0we6ADCgEBonQEcm BwBgkqhkiG9xIBAgIDAH5hMF+gAwIBBaEDAgEepBEYDzIwMTAwMzExMTAzNjAzWqUFAgMEDFimAwIBKakYGxZJTlRSQU5FVC5CQVJDQVBJTlQuQ09NqhowGK ADAgEBoREwDxsNTERORFdNMjg2MzgwJA=='. ---> System.Net.WebException: The remote server returned an error: (401) Unauthoriz ed. ---> System.ComponentModel.Win32Exception: The target principal name is incorrect at System.Net.NTAuthentication.GetOutgoingBlob(Byte[] incomingBlob, Boolean throwOnError, SecurityStatus& statusCode)

任何帮助表示赞赏，

在您的客户端的配置，您需要在“端点”元素内添加一个附加元素以指定该服务正在运行的主体。以下是一个示例：

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

这应该允许在客户端和主机之间建立通道时发生适当的身份验证。如果服务使用不同的帐户运行，则需要相应地调整该值（即，如果它正在使用系统帐户作为Windows服务运行，则它将类似于'host/mymachine.mydomain.com'）。
