Where can I find a good open source user account management class/library in PHP?

Question

I am looking for a good framework for user and user group management in PHP. I want a to be able to add/edit/delete profile, save in a db; add/edit/delete groups; assign a user as group leader, nothing more.

I tried http://www.phpclasses.org. There are many options there but I simply don't know which once to go for. I don't have much time to download each one to try out so I am wondering if anyone has come across anything good and useful. Preferably free but I don't mind paying or donating.

Ideas?
