ASP.NET网站中托管的WCF服务 - Windows身份验证无法正常工作

I am hosting a WCF service in an asp.net website. On IIS it has integrated windows authentication setting. I'm making call to wcf service method from one of the asp.net website pages using jquery. But, unfortunately, that call is asking for windows username/password which I already provided for the website. My understanding is the authentication token will be automatically passed to the wcf call as well.I am hosting a WCF service in an asp.net websit
