Puppet

One of my clients remarked that he was working through the Learning Puppet track and ran into a stack trace.

Learning Puppet teaches the puppet resource command, the later has an exercise for the ssh_authorized_key resource (on http://docs.puppetlabs.com/learning/manifests.html). Running puppet resource ssh_authorized_key hunner throws a stack trace because lib/puppet/type/ssh_authorized_key:104, @parameters[:target] is nil.

err: /Ssh_authorized_key[hunner]: Could not evaluate: Cannot write SSH authorized keys without user

I have two ssh-rsa keys in ~/.ssh/authorized_keys2
