Silverlight + WCF - Windows集成验证

一个基于Silverlight的intranet应用，需要启用Windows集成验证，设置如下：

1. IIS (7.5) - 启用Windows Authentication

2. web.config:

<authenticationmode="Windows"/>
<identityimpersonate="true"/>
<authorization>
<denyusers="?"/>
</authorization>

以上配置，ASP.NET部分的集成验证可工作。Silverlight调用WCF会遇到异常，还需：

1. 配置Silverlight WCF custom binding httpTransport：

<bindingname="mybinding"
closeTimeout="00:05:00"openTimeout="00:05:00"receiveTimeout="00:05:00"
sendTimeout="00:05:00">
<binaryMessageEncoding/>
<httpTransportauthenticationScheme="Negotiate"/><!--requiredbyWindowsAuth.Use"Negotiate"onWindows2008/Windows7-->
</binding>

MSDN文档严重有误，还好下面的评论给出了正解

2.配置WCF endpoint: 去掉mex endpoint
