279590 Install Password Protect PHP

I need a free PHP script installed, it is called Advanced Password Protect and you can get more info about the script at the web site: [login to view URL] I tried to install the script my self but I was unable to get it to work completly. I want to set-up only a username or password (not both) that will redirect the user to a web page that is related to the username or password. Each username/password would redirct the user to a spacific web page. I also want the users to only beable to log-in on the home page or index page. If you are interested please take a look at the script. Thank You Highly! Jason
