rkhunter warning about ssh root access when that access is not allowed on the system

I just ran rkhunter --check and all was good except this: Checking if SSH root access is allowed [ Warning] What does this warning mean? SSH root access is not allowed on this system. EDIT #1 Here is how my /etc/ssh/sshd_config is set: PermitRootLogin no and rkhunter.conf root ~ # cat /etc/rkhunter.conf | grep ALLOW_SSH_ROOT_USER #ALLOW_SSH_ROOT_USER=no ALLOW_SSH_ROOT_USER=unset
