kerberos

I'm currently writing a puppet module to automate the process of joining RHEL servers to an AD domain, with support for Kerberos.

Currently I have problems with automatically obtain and cache Kerberos ticket-granting ticket via 'kinit'.

If this were to be done manually, I would do this:

kinit [email protected]

This prompts for the AD user password, hence there is a problem with automate this.

How can i automate this? I've found some posts mentioning using kadmin to create a database with the ad users password in it, but I've had no luck.

Thanks for input
