Rocks Cluster Compute nodes Ask for Password

After installing the compute nodes on a new Rocks Cluster it was found that a few nodes kept asking for SSH password. These should have been passwordless SSH and it was working on some of the compute nodes.

Try the following #rocks sync host sharedkey compute 

Try #rocks run host "/opt/rocks/bin/411get --all" 

if that works, 

Try #rocks sync users on the frontend

This cured the password prompt problem on the cluster.
