[Beowulf] Password less ssh

Are you trying to ssh to root account? Then make sure you permit root to
~>grep Root /etc/ssh/sshd_config
PermitRootLogin yes

if you want to ssh to kuser account why the hack you copy public key to
root's .ssh? because your home is shared just cp id_dsa.pub
and then make sure that permissions on .ssh directory are restrictive.

hope this helps
