ssh -l root

[Cimarron Ryan]

I'd like to be able to ssh to root on my local machine.

I've created a key pair for the user, and I've copied the user's public key
into /root/.ssh/authorized_keys.  But whenever I try to "ssh -l root
localhost", I'm asked for the root password (not the passphrase for the key,
the actual root passsword on the machine).

As I understand it, sshd defaults to allow root to login with ssh.  Anyone
know what could be going wrong?
