 If you prevent accounts with a "*" from logging in with a ssh key you
 will break POLA.  I know that I have several systems where the
 password in master.passwd is set to "*" and I then log in via ssh
 keys.
 
 Also a "*" in the password file does not prevent a user logging in
 when authenticating via Kerberos.
