我正在编写一个 WCF 服务，需要模拟和 session 。

当我试图在我的本地机器上调用它时没问题，但在远程机器上它总是失败并出现这样的错误:

Security Support Provider Interface (SSPI) authentication failed. The server may not be running in an account with identity 'host/hostname'. If the server is running in a service account (Network Service for example), specify the account's ServicePrincipalName as the identity in the EndpointAddress for the server. If the server is running in a user account, specify the account's UserPrincipalName as the identity in the EndpointAddress for the server.

如果我提供了一个 upn，它会抛出身份失败异常。

这是我的配置:

服务器配置(APP):

<system.serviceModel>    
    <behaviors>
      <serviceBehaviors>
        <behavior name="default">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
          <serviceAuthorization impersonateCallerForAllOperations="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <netTcpBinding>

          <reliableSession enabled="true" inactivityTimeout="24:00:00" ordered="true"/>          
          <security mode="TransportWithMessageCredential">
            <message clientCredentialType="Windows" />
            <transport clientCredentialType="Windows"/>          
          </security>
        </binding>
      </netTcpBinding>
    </bindings>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true"/>
    <services>
      <service behaviorConfiguration="default" name="DataService.DataService">
        <endpoint address="" binding="netTcpBinding" bindingConfiguration="DataService.netTcpBinding"

        <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://address:4504/"/>
            <add baseAddress="net.tcp://address:4503/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
</system.serviceModel>

客户端配置:

        </bindings>
        <client>

              </identity>
            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

最佳答案

Windows 服务使用用户主体名称或服务主体名称 (documentation) 注册自己。引用该链接:“如果服务在 LocalSystem、LocalService 或 NetworkService 帐户下运行，默认情况下会以主机/的形式生成服务主体名称 (SPN)，因为这些帐户可以访问计算机的SPN 数据。如果该服务在不同的帐户下运行，Windows Communication Foundation (WCF) 会生成 @ 形式的 UPN。“事实上，这句话与您的错误消息所陈述的内容非常相似。看来……

a) 如果该服务在本地服务帐户或类似的标准帐户下运行，那么您需要调整您的客户端配置文件以拥有它，其中实际服务器的名称是“地址”并且端点在端口 4503 上运行:

<identity>
     <servicePrincipalName value="host/address:4503" />
</identity>

b) 或者，如果您在专用服务帐户下运行(我们在域“MyDomain”上将其称为“ServiceAccount”)，那么您需要

<identity>
     <userPrincipalName value="ServiceAccount@MyDomain" />
</identity>

请注意，您可能需要在两种情况下都使用完全限定的域名，包括森林和树木级别。对于私有(private) LAN/WAN 内的简单域，这意味着 address.MyDomain.local 和 ServiceAccount@MyDomain.local。如果您的域位于名为 MyTree 的树中，那么它将是 ServiceAccount@MyDomain.MyTree.local；如果它位于名为 MyForest 的林中，则它将是 Serviceaccount@MyDomain.MyTree.MyForest.local(对于 ServicePrincipalName 也是类似的)。需要完全限定名称 when you are using Kerberos用于身份验证。
