Question

Is there a good graphical/pseudographical/web-based tool for managing Linux users and groups?

To see them all at once, operate them (create, remove, associate (add/remove users to groups), modify) with couple of clicks?

Answer 1

Webmin is generally considered to be pretty good at that and is probably already part of whatever distro you use.

If you look at their screenshot page, you can actually see some screenshots of creating and managing users.
