The Users and Groups control panel lets you identify the names and
passwords of users with whom you want to share specific folders or
applications. With this, you can also set certain abilities regarding
whether or not the user can connect to shared resources, or whether they
change their connection password. User Setup also lets you create group
icons and put multiple users into these groups.
