If you are performing a workstation-class installation, please skip
ahead to the section called GUI X Configuration Tool.
If you are performing a server-class installation, please skip ahead to
the section called Preparing to Install.
You may skip this section if you will not be setting up network
passwords. If you are unsure as to whether you should do this, please
ask your system administrator for assistance.
Unless you are setting up NIS authentication, you will
notice that both MD5 and
shadow passwords are selected (see Figure 15-20). We recommend you use both to
make your machine as secure as possible.
To configure the NIS option, you must be connected to an NIS network. If
you are unsure whether you are connected to an NIS network, please ask
your system administrator.
MD5 Password -- allows a long password to be
used (up to 256 characters), instead of the standard eight letters
or less.
Shadow Password -- provides a secure method of
retaining passwords. The passwords are stored in
/etc/shadow, which is readable only by root.
Enable NIS -- allows you to run a group of
computers in the same Network Information Service domain with a
common password and group file. There are two options to choose from
here:
NIS Domain -- this option allows you to
specify which domain or group of computers your system belongs
to.
NIS Server -- this option 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.
Enable LDAP -- LDAP consolidates 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 Chapter 7.
There are two options to choose from here:
Enable Kerberos -- Kerberos is a secure system
for providing network authentication services. For more information
about Kerberos, see Chapter 8. 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 very 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.
