Get a Kerberos ticket in Linux at IU

To get a Kerberos ticket, you need to issue a kinit command. To do so:

1. Install the package that provides the kinit command:
   • RHEL or Fedora: krb5-workstation
   • Ubuntu or Debian: krb5-user
2. In /etc, place the following into a file called krb5.conf:

   [domain_realm]
   	.ads.iu.edu = ADS.IU.EDU
   	.indiana.edu = ADS.IU.EDU
   	.iu.edu = ADS.IU.EDU
   	.iub.edu = ADS.IU.EDU
   	.iue.edu = ADS.IU.EDU
   	.iuk.edu = ADS.IU.EDU
   	.iun.edu = ADS.IU.EDU
   	.iupui.edu = ADS.IU.EDU
   	.ius.edu = ADS.IU.EDU
   	.iusb.edu = ADS.IU.EDU
   	indiana.edu = ADS.IU.EDU
   	iu.edu = ADS.IU.EDU
   	iub.edu = ADS.IU.EDU
   	iue.edu = ADS.IU.EDU
   	iuk.edu = ADS.IU.EDU
   	iun.edu = ADS.IU.EDU
   	iupui.edu = ADS.IU.EDU
   	ius.edu = ADS.IU.EDU
   	iusb.edu = ADS.IU.EDU
   
   [libdefaults]
   	default_realm = ADS.IU.EDU
   
   [realms]
   	ADS.IU.EDU = {
   		kdc = ads.iu.edu:88
   	}

3. Issue kinit username to get your ticket.

To see your tickets, issue a klist command.
