So is this intentional that you're using passwd-file instead of  
passwd? passwd-file isn't really meant to be used to read the  
standard /etc/passwd and so it gives these kind of warnings at  
startup. If you're using this as passdb, it'll probably allow user  
"+" to log in with an empty password.
