Using Basic IIS Authentication with the JSAPI 3.2 Proxy

[AndrewBrown1]

hello,

I'm using the basic ISS Authentication model for simplicity and I want to secure our mapping services using tokens and the IIS authentication built into the JSAPI proxy security. I only have two requirements for doing this:

-Don't ask the end-user to log in to the mapping application again after logging into the website (via basic authentication)
-Prevent folks who didn't authenticate with IIS from accessing the web services.

Is this possible? I read about it and the page pointed me to a Microsoft site saying it had instructions, but I'm clueless here:
http://msdn.microsoft.com/en-us/library/aa292471(VS.71).aspx

Also, how would I configure my proxy.ashx page to interact with IIS? We're using the web adaptor, if that matters.

Thanks for your help.
