For most, there's a steep learning curve to getting Kerberos up and going.
You will need a Kerberos Domain Controller configured and tested prior to
attempting to get GSSAPI working. I recommend reading through this:

In short, on the client you'll need to initialize your ticket cache with
kinit or a similar tool and use klist to verify and view your ticket cache.
