Setting up Kerberos on an Ubuntu Workstation

Posted Tuesday, July 12th 2011 in Linux - Permalink

First, we need to install the Kerberos client software,

~ sudo apt-get install krb5-user krb5-config

During installation, the configuration will ask you to enter the realm (domain) of authentication, and the authoritative servers.

After this is set up, test it by getting a ticket from the server:

~ kinit user@REALM.COM
Password for user@REALM.COM:
~ klist
Ticket cache: FILE:/tmp/krb5cc_1000
Default principal: user@REALM.COM

Valid starting     Expires            Service principal
07/12/11 13:42:24  07/13/11 13:42:10  krbtgt/REALM.COM@REALM.COM

You should now be able to use network services requiring Kerberos authentication.
