WCF自托管REST服务器(HTTPS)不断请求客户端身份验证

我创建了一个自托管的WCF REST服务器(不带IIS)。当我启用SSL支持时,当我在chrome中测试站点时,会一直要求我提供客户端认证。

下面是我的app.config,我认为它禁用了客户端身份验证。我这里有什么东西不见了吗?

app.config代码:

 <system.serviceModel>
<services>
  <service behaviorConfiguration="ADConnectorLibrary.Service1Behavior" name="ADConnectorLibrary.ADConnectorLibrary">
    <endpoint address="" binding="webHttpBinding" bindingConfiguration="webHttpTransportSecurity" behaviorConfiguration="web" contract="ADConnectorLibrary.IADConnectorLibrary" >
    </endpoint>
    <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange"/>
    <host>
      <baseAddresses>
        <add baseAddress="https://ADDRESS:8888/ADConnectorLibrary/"/>
