   3 Subject: auth2-none.c: avoid authenticate empty passwords to mess up with PAM
   4
   5 If UsePAM, PermitEmptyPasswords, PasswordAuthentication are enabled. The ssh daemon
   6 will try to authenticate an empty password, resulting in login failures of any user.
   7 If PAM is enabled, then we should leave the task of password authentication to PAM.
