You also need to create an account with an empty password to log
into. It also means that the user can log in locally without using a
password. (Just hit enter when it asks for a password.) I have not
tested it, but sshd may still ask for a password, but allow you to
hit enter when asked. The default setting will not let you connect
to this type of account using passwords. I believe it will let you
connect using key pairs. At a guess, I would say it is designed to
prevent remote logins using a "guest" account that does not require
a password...
PermitEmptyPasswords
When password authentication is allowed, it specifies whether the
server allows login to accounts with empty password strings. The
default is ``no''.
