10.7 Changing the User Authentication Method
When your machine is connected to a network, you can change the authentication
method you set during installation. The following options are available:
NIS
Users are administered centrally on a NIS server for all systems in the network.
For details, see Chapter 3, Using NIS (↑Security Guide).
LDAP
Users are administered centrally on an LDAP server for all systems in the network.
For details about LDAP, see Chapter 4, LDAP—A Directory Service (↑Security
Guide).
You can manage LDAP users with the YaST user module. All other LDAP settings,
including the default settings for LDAP users, have to be dened with the YaST
LDAP client module as described in Section “Conguring an LDAP Client with
YaST” (Chapter 4, LDAP—A Directory Service, ↑Security Guide) .
Kerberos
With Kerberos, a user registers once and then is trusted in the entire network for
the rest of the session.
Samba
SMB authentication is often used in mixed Linux and Windows networks. For de-
tails, see Chapter 19, Samba (↑Reference) and Chapter 5, Active Directory Support
(↑Security Guide).
To change the authentication method, proceed as follows:
1 Open the User and Group Administration dialog in YaST.
2 Click the Authentication Settings tab to show an overview of the available
authentication methods and the current settings.
3 To change the authentication method, click Congure and select the authen-
tication method you want to modify. This takes you directly to the client con-
guration modules in YaST. For information about the conguration of the
appropriate client, refer to the following sections:
NIS: Section “Conguring NIS Clients” (Chapter 3, Using NIS, ↑Security
Guide)
LDAP: Section “Conguring an LDAP Client with YaST” (Chapter 4, LDAP—A
Directory Service, ↑Security Guide)
4 After accepting the conguration, return to the User and Group Administration
overview.
5 Click OK to close the administration dialog.
