Chapter 26. Authentication Configuration
Figure 26.1. User Information
The following list explains what each option configures:
• Enable NIS Support — Select this option to configure the system as an NIS client which connects
to an NIS server for user and password authentication. Click the Configure NIS button to specify
the NIS domain and NIS server. If the NIS server is not specified, the daemon attempts to find it via
broadcast.
The ypbind package must be installed for this option to work. If NIS support is enabled, the
portmap and ypbind services are started and are also enabled to start at boot time.
• Enable LDAP Support — Select this option to configure the system to retrieve user information via
LDAP. Click the Configure LDAP button to specify the LDAP Search Base DN and LDAP Server.
If Use TLS to encrypt connections is selected, Transport Layer Security is used to encrypt
passwords sent to the LDAP server.
The openldap-clients package must be installed for this option to work.
For more information about LDAP, refer to the Reference Guide.
• Enable Hesiod Support — Select this option to configure the system to retrieve information from a
remote Hesiod database, including user information.
The hesiod package must be installed.
• Winbind — Select this option to configure the system to connect to a Windows Active Directory or
a Windows domain controller. User information can be accessed, as well as server authentication
options can be configured.
• Cache User Information — Select this option to enable the name service cache daemon (nscd)
and configure it to start at boot time.
The nscd package must be installed for this option to work.
