How do you enable ssh login on OS X 10.8 (Mountain Lion) for a
user with an empty password? I've seen others asking this question, and like me it's for the same reason: a parent who can't deal with passwords. So "set a password" is not an option.
I found references to adding "nullok" to various PAM config files. Didn't work.
Found sshd config "PermitEmptyPasswords yes". Didn't work.
I've done a diff on "ssh -vvv" between a successful ssh with a password-enabled
account and the one with no password.
