This might be relevant (though IIS is mentioned)....
Q. I have an IIS web server with Windows Integrated Authentication turned on. Can the CA APM for Web Servers monitor this server?
A. No, the CA APM for Web Servers cannot monitor an authenticated web server. CA APM for Web Servers does not provide an option to specify the username and password to connect to the web server. To monitor these web servers, the stats page can be selectively given anonymous access to the CA APM for Web Servers.

Not sure if that is possible with the current design
