I missed the rest of this thread so sorry its its been said already. As
far as I knew the directive
PermitRootLogin without-password
in /etc/ssh/sshd_config
should accomplish what was requested.

However a note later in the default sshd_config file regarding the
UsePAM setting says
'Depending on your PAM configuration,
 PAM authentication via ChallengeResponseAuthentication may bypass
the setting of "PermitRootLogin without-password".'

So I'd be interested to know if by default this is the case.
