Question: in my experience sshd will not allow connections to users who 
have no password set, even when password-auth is not used. This happened 
on my wife's laptop, for example, where I ended up having to create a 
dummy user for myself that had a password, since she didn't want her 
account to have one.

Does SYSTEM have some sort of password after all?
