How do you use the source keyword in Puppet’s DSL (when writing a manifest)?

How Do You Set Up Passwordless SSH to a Windows Server?

Problem scenario
Are are asking yourself “why am I being prompted for a password when my SSH keys were set up correctly?”  When the contents of the .pub file (the public key) are placed into the authorized_keys file (in the /home/jdoe/.ssh/ folder of a client machine), the user should be able to SSH over to the server with no password — unless the SSH key was generated with a passphrase.  Assuming the SSH key was generated with an ssh-keygen command and no corresponding passphrase was entered at the time of creation,
