I tend to set it to without-password to allow a remote root entry only via RSA/DSA keys, also making sure to restrict it further with as many applicable options for AuthorizedKeysFile ( man sshd ) This is done as a restricated remote root backdoor as well as automated network backups via dump

I think there may be a compromise solution here... In short: it is good to make people log in as a normal user before trying to log in as root, because that way an attacker needs to compromise a normal user before starting on root. The standard way of doing this is to use su, but that only
