about LDAP, refer to Official Red Hat Linux Reference Guide, Lightweight Directory Access Pro-
tocol (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 authentica-
tion.
–
SMB Workgroup — Indicates which workgroup the configured SMB servers are in.
