creating login page

I am fairly new to webdesign so please forgive me if i don't state my problem clearly. I've created a site containing my homepage and other pages, that are linked from it. Now i want to create a login page. I am using Dreamweaver MX on my win2000 laptop and uploading my files using ftp to a linux webserver. Here is the problem: I use the standard login page template that comes with Dreamweaver ( yeah, i am lazy) but when i want to change the server behaviour of my page using WINDOW>SERVER BEHAVIOUR>USER AUTHENTICATION i get a window that wants me to fill in the database table and columns that contains the users and passwords. On this window there are also fields that are connected to the form on my loginpage and those fields are ok. So where and how can i put my table of users and make it clear to DREAMWEAVER?
