Quick Start Guide

LDAP
Users are administered centrally on an LDAP server for all systems in the network.
More information is available in Section “Conguring an LDAP Client with YaST”
(Chapter 4, LDAP—A Directory Service, ↑Security Guide).
NIS
Users are administered centrally on an NIS server for all systems in the network.
See Section “Conguring NIS Clients” (Chapter 3, Using NIS, ↑Security Guide) for
more information.
Windows Domain
SMB authentication is often used in mixed Linux and Windows networks. and
Section “Conguring a Linux Client for Active Directory” (Chapter 5, Active Direc-
tory Support, ↑Security Guide).
Along with user administration via LDAP and NIS, you can use Kerberos authentication.
To use it, select Set Up Kerberos Authentication. For more information on Kerberos,
refer to Chapter 6, Network Authentication with Kerberos (↑Security Guide).

Password for the System Administrator root
If you have not chosen Use this Password for the System Administrator in the previous
step, you will be prompted to enter a Password for the System Administrator root.
Otherwise this conguration step is skipped.
root is the name of the superuser, or the administrator of the system. Unlike regular
users (who may or may not have permission to access certain areas or execute certain
commands on the system), root has unlimited access to change the system congu-
ration, install programs, and set up new hardware. If users forget their passwords or
have other problems with the system, root can help. The root account should only
be used for system administration, maintenance, and repair. Logging in as root for
daily work is rather risky: a single mistake could lead to irretrievable loss of system
les.
For verication purposes, the password for root must be entered twice. Do not forget
the root password. Once entered, this password cannot be retrieved.
The root can be changed any time later in the installed system. To do so run YaST
and start Security and Users > User and Group Management.
WARNING: The root User
The user root has all the permissions needed to make changes to the system. To
carry out such tasks, the root password is required. You cannot carry out any
administrative tasks without this password.
