The first key is the Emulab-generated ssh v1 key.  The second could be a user
loaded key.  A user with this problem should first verify that they have
uploaded a pubkey to Emulab.  See:

  http://users.emulab.net/trac/emulab/wiki/kb70

and then if they cannot login using that key, run "ssh -v <your-ops-node>"
so it will provide more information about why authentication is failing.
One reason is that we might not have properly distributed the pubkey to
ops after they upload it.  They (well you, since they cannot login :-)
can look at their ~user/.ssh/authorized_keys file and ensure the key
showed up.
