[Beowulf] Passwordless ssh - strange problem

I forgot to look in the secure logs (that tells how it's been since I had
to deal with a problem with ssh :)   ).

Anyway, what I'm seeing the logs is:

Authentication refused: bad ownership or modes for directory /home/panasas

This is the home directory of the account. /home/panasas is NFS exported
from the head node to the compute nodes. I wonder if there isn't a problem
with account?

BTW - I did set 600 on id_rsa (and id_dsa). I set 644 on authorized_keys
and id_rsa.pub id_dsa.pub. I'll also copy authorized_keys to authorized_keys2
I'm not sure if I'm using ssh2 or not (actually it's not even my cluster).

Thanks!

Jeff
