How do I display shape files with a google-like interface in a web application?

I found a tutorial at http://spatialhorizons.com/2007/05/19/mapserver-1-10-minute-tutorial/ which uses an earlier version of map server (the tutorial uses v2.2.6 and I am using v3.0.6) and followed it with no problems up to the second to last point. I know I have set up map server correctly since when I navigate to localhost in my browser I see the welcome screen. However, when I select the ka-map sample interface link I get the error: "The requested URL /kamap was not found on this server."

Could someone please advise about where I am going wrong?
