I'm not sure if this is what you want, but I found a tutorial on
Net Tuts+ that has a
simple login system that would require PHP and MySQL.
Idk, I went ahead and just entered "login" as a keyword there and you can view the
results here and you could see if you like something.

You could also try searching "custom login system" at google. :|
Net Tuts+ is actually very nice, yet has it's moments. If you have access to WHM with no limitations (So basically if you have your own server) you could do this, but without that access I would go with what Mikeplyts suggested and use that.
By the way, what are you using this area for? If you are doing just files and want to have your own designed template in the "staff" are, go for Net Tuts+. If you want a true staff area that is designed for production, look into a product management software of sorts. Two are already in Fantastico under your hosts cPanel (if they care about you) ready for installing, they are called dotProject and PHProjekt.
DotProjectProject Management featuring companies, projects, tasks (with Gantt charts), forums, files, calendar, contacts, tickets/helpdesk, language support, user/module permissions, themes.
PHProjektProject Management featuring optional group system, privileges, calendar, contacts, time card, projects, chat, forum, request tracker, mail client, files, notes, bookmarks, to-do list, reminder, voting, language support.
Both work very well.
Also look into some collaboration software, they differ somewhat from Project Management software, but are kinda cool.
Now, if you are looking for login security, you need a SSL certificate as well. That's a whole other story, and a somewhat complicated one.
