Learn to make use of the Kerberos authentication tickets in the day-to-day network services on IBM® AIX® V6 and discover how Kerberos can be useful in getting rid of the password hassles for network service logons. This is another method towards achieving single sign on (SSO) on an AIX system network.

Introduction

The network applications in AIX (for instance, telnet, FTP, and r-commands like rlogin, rsh, rcp, and more) inherently support Kerberos authentication. All the administrators need to do is to install and configure Kerberos and configure AIX system (in turn its applications) to use that Kerberos setup for authentication. The Kerberos authentication means that once you have a valid Kerberos ticket (obtained by a manual /usr/krb5/bin/kinit or integrated login), the network applications can use this ticket as your authentication token and once authenticated successfully, you will be given access without being asked to enter your password.
