Please help

Hi, I need a simple web mangement script which allows me to add manually passwords and usernames of my students to redirect them to specific folders as they will log in my website. If the script could also record the activities it would be great, but just now I’m not a programmer so I don’t need anything fancy or related to mySql. I tried installing several scripts from hotscripts or cgi-resource but I always get error 500 and the “fopen access denied” error in my log.
Although I was succesfull in installing all kinds of other scripts I seem unable to find a script or this specific purpose.
I would be very grateful indeed if someone could suggest me a (possibly) freeware script already succesfully tested at Dreamhost.
Thanks in advance … and sorry if I posted this in two forum.
