====== Add a user to the Rocks cluster ======

As **root**:

  - For a normal user: ''useradd -g users jp''
    - For a super user: ''useradd -G users,wheel jp''
  - Set the password with ''passwd jp''
  - We now need to ''rocks sync users'' to sync the user with all of the cluster.
  - Logout with **root** and login with your new user.  You should be able to login with no password on the compute nodes.
