Cron Jobs and Kerberos

If at all possible run your cron jobs on server machines that don’t use Kerberos authentication. If your cron job expects access to something in your home directory, or some other NFS resource, (which is probably will) you need to make sure you have a valid kerberos ticket for the cronjob to be able to access the NFS data.

For your cron jobs to be able to access NFS data you’ll first need to initialize and renew a Kerberos ticket on the machine the cron job is scheduled to run.

For special projects it might be possible to create a keytab file that can be used to ease initializing the Kerberos ticket for cron jobs that need to run on workstations. Please contact the cat for more information.
