I need a simple authorization system added to this site here: [url removed, login to view]
There are 6 pages which are "protected" in this website. 1 of the 6 pages can be seen by anyone who belongs to any "group". The other 5 pages are specific to a group, and can only be viewed by the group's members.
The group members are decided by 5 different pages on the server. Each page is specific to a group, and these pages are in HTML.
The authorization process just involves the user entering their name and subgroup, and the code checking to see their name matches the group that they said they belong to. If it matches, it leads them to a content page.
This is the basic idea. I will answer any questions you may have, and of course, provide much more details when I choose a freelancer.
