    NL and NP login - Can't find the difference


      Hi all,


      Recently I want to add an account in the way that, it can only be login via SSH key.


      Initially, I thought that NL means that even with SSH key setup, the login will still fail. But I am wrong.


      So with testing with NL and NP status, I realize the following behaviour


      1) login with passwd - failed ( of course)

      2) login via su  ( both works )

      3) login via ssh ( both works )



      The only difference is, with NL , the password in /etc/shadow for that account is set as NP

                                           with NP, the password in /etc/shadow for that account is empty.



      So what is the fundamental difference between NL and NP ? they seems to behave the same for me  ?
