不安全的WCF服务引发SecurityAccessDeniedException

正在尝试运行演示服务，我正在使用以下配置

<bindings>
  <basicHttpBinding>
    <binding name="basicBinding">
      <security mode="None">
        <transport clientCredentialType="None" />
      </security>
    </binding>
  </basicHttpBinding>
  <wsHttpBinding>
    <binding name="wsBinding">
      <security mode="None">
        <transport clientCredentialType="None" />
        <message establishSecurityContext="false" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>
<services>
    <service behaviorConfiguration="Integration.Server.ImportServiceBehavior" name="Integration.Server.ImportService">
        <endpoint name="ImportServiceSoap" 
          behaviorConfiguration="NoIpConfiguration" 
          address="soap" binding="basicHttpBinding"
          bindingConfiguration="basicBinding"
          contract="Integration.Server.IImportService"/>
        <endpoint name="ImportServiceSoap12" 
          behaviorConfiguration="NoIpConfiguration" 
          address="soap12" binding="wsHttpBinding" 
          bindingConfiguration="wsBinding"
          contract="Integration.Server.IImportService">
            <identity>
                <dns value="localhost"/>
            </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
    </service>
</services>
<behaviors>
    <serviceBehaviors>
        <behavior name="Integration.Server.ImportServiceBehavior">
            <serviceMetadata httpGetEnabled="true"/>
            <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
    </serviceBehaviors>
<endpointBehaviors>
    <behavior name="NoIpConfiguration">
      <wsdlExtensions location="http://*** external server address ***/IntegrationServer/ImportService.svc" singleFile="true"/>
    </behavior>
  </endpointBehaviors>
</behaviors>
<extensions>
  <behaviorExtensions>
    <add name="wsdlExtensions" type="WCFExtras.Wsdl.WsdlExtensionsConfig, WCFExtras, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
  </behaviorExtensions>
</extensions>

我们的行为配置（NoIpConfiguration）在哪里？这里看起来像“服务器端配置”：异常堆栈跟踪是什么？我已经在问题中添加了堆栈跟踪。只是一个猜测，但服务是否在部分信任的托管环境中运行，WCFExtras代码是否与反射有关。Emit？使用反射时，在部分信任的服务中运行可能会导致某些访问冲突。
