Database WCF服务未模拟客户端

物流： 1台运行WCF服务的服务器。 1台运行WCF服务数据库的服务器

问题: 我在一台服务器上运行了一个WCF服务，它连接到一个单独的服务器，以获取需要检索的必要数据。我的问题是，当从客户端计算机调用服务时，我收到一个数据库sql错误，指出“用户“NT AUTHORITY\ANONYMOUS LOGON”登录失败”。我相信我已经将WCF服务设置为使用模拟

WCF服务器配置：

<bindings>
  <ws2007HttpBinding>
    <binding maxReceivedMessageSize="214748">
      <security mode="Message">
        <transport clientCredentialType="Windows"
                   proxyCredentialType="Windows" realm="" />
        <message clientCredentialType="Windows" negotiateServiceCredential="true"
                 algorithmSuite="Default" establishSecurityContext="true" />
      </security>
    </binding>
  </ws2007HttpBinding>
</bindings>
<services>
  <service behaviorConfiguration="Host.ServiceBehavior" name="Wcf.MyWebService">
    <endpoint address="" behaviorConfiguration=""
              binding="ws2007HttpBinding" contract="Wcf.MyWebServiceSoap">
      <identity>
        <servicePrincipalName value="ServerMachineName" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding"
              contract="IMetadataExchange" />
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="Host.ServiceBehavior">
      <serviceMetadata httpsGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
      <serviceAuthorization impersonateCallerForAllOperations="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

客户端配置和代码：

我正在编程设置以下配置项：

public void TestWebMethod()
{
  WS2007HttpBinding binding = new WS2007HttpBinding();
  EndpointAddress endpoint = new EndpointAddress("uri");
  ServiceClient client = new ServiceClient(binding, endpoint);
  client.ClientCredentials.Windows.AllowedImpersonationLevel =
                               TokenImpersonationLevel.Impersonation;
  client.ClientCredentials.Windows.AllowNtlm = true;
  string result = client.TestWebMethod();
  client.Close();
}

模拟允许服务访问服务的本地资源，但不允许服务访问外部资源（例如，另一个服务）

必须将允许的模拟级别设置为TokenImpersonationLevel.Delegation

---

我想我已经试着把它改成了授权，但没有成功。但我会再试一试。服务和客户端的配置项看起来正确吗？我在服务端添加了一些代码来记录调用方法时进入的模拟级别。我已经在客户端上将AllowedImpersonationLevel设置为Delegation，但是日志显示它仍然设置为Impersonation。我仍然无法登录数据库。

public void TestWebMethod()
{
  WS2007HttpBinding binding = new WS2007HttpBinding();
  EndpointAddress endpoint = new EndpointAddress("uri");
  ServiceClient client = new ServiceClient(binding, endpoint);
  client.ClientCredentials.Windows.AllowedImpersonationLevel =
                               TokenImpersonationLevel.Impersonation;
  client.ClientCredentials.Windows.AllowNtlm = true;
  string result = client.TestWebMethod();
  client.Close();
}

client.ClientCredentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Delegation;
