Chapter 3. Installing Red Hat Linux 65
NIS Domain allows you to specify the domain or group of computers your system belongs
to.
Use broadcast to find NIS server allows you to broadcast a message to your local area
network to find an available NIS server.
NIS Server causes your computer to use a specific NIS server, rather than broadcasting a
message to the local area network asking for any available server to host your system.
Note
If you have selected a medium or high firewall to be setup during this installation, network authen-
tication methods (NIS and LDAP) will not work.
Enable LDAP tells your computer to use LDAP for some or all authentication. LDAP consol-
idates certain types of information within your organization. For example, all of the different lists
of users within your organization can be merged into one LDAP directory. For more information
about LDAP, refer to the Official Red Hat Linux Reference Guide, Lightweight Directory Access
Protocol (LDAP). You can choose from the following options:
LDAP Server allows you to access a specified server (by providing an IP address) running
the LDAP protocol.
LDAP Base DN — allows you to look up user information by its Distinguished Name (DN).
Use TLS (Transport Layer Security) lookups — this option allows LDAP to send encrypted user
names and passwords to an LDAP server before authentication.
Enable Kerberos Kerberos is a secure system for providing network authentication services.
For more information about Kerberos, see Using Kerberos 5 on Red Hat Linux in the Official Red
Hat Linux Reference Guide. There are three options to choose from here:
Realm — this option allows you to access a network that uses Kerberos, composed of one or a
few servers (also known as KDCs) and a potentially large number of clients.
KDC this option allows you access to the Key Distribution Center (KDC), a machine that
issues Kerberos tickets (sometimes called a Ticket Granting Server or TGS).
Admin Server this option allows you to access a server running kadmind.
Enable SMB Authentication Sets up PAM to use an SMB server to authenticate users. You
must supply two pieces of information here:
SMB Server Indicates which SMB server your workstation will connect to for authentication.
SMB Workgroup — Indicates which workgroup the configured SMB servers are in.
Tip
To change your authentication configuration after you have completed the installation, use the auth-
config command.
Type the authconfig command in a shell prompt. If you are not root, it will prompt you for the root
password to continue.
