Creating a file with a principal secret

The secrets provided will be used in authentication. The current information will be checked against this principal secret file to give authentication.

For creating a secret, let's follow these steps:

{

               }, 
               { 
                     "principal":"agent", 
                     "secret":"agents_secret"

} 

Save the file using :wq!, and then exit. Repeat these steps on all three master servers.
