The
Root is, as noted often here, all powerful. Generic users can
be restricted to the point of being able to read only a single
file, or have full run of the system as the SuperUser (su).
This section will help you better understand how the
permissions system works, beyond what you learned in
Chapter 5, ???Getting Started with openSUSE.???
Setting Up User Accounts in YaST
The first user account is set up during the openSUSE installation. Adding users is a simple
task in YaST.
In YaST, go to Security and Users, then User Management. YaST will review the current
user accounts and display them in the first screen (see Figure 19.1).
Besides the standard operations of Adding and Deleting users, you can perform several
user-related tasks from this screen:
. Change passwords and access rights for existing users
. Allow some users to log in without a password
. View and edit system users (more about this in the next section)
. Set default permissions and groups for new users
. Set password encryption standards
. Configure user-related information for Lightweight Directory Access Protocol
(LDAP), Samba, Network Information Service (NIS), and Kerberos services
