True! But it's information stored in a rather non-standard way. Many user
configuration tools use their own default string, usually "*", to lock
accounts. And the console "passwd" or "yppasswd" command does not usually
allow the use of pre-encrypted passwords, so you have to either edit
/etc/shadow or /etc/passwd by hand (always dangerous and prone to typos!),
or re-rewritng your user configuration tools to add a new "NP" option, etc.

I'm just saying it's adding an additional password option in a non-standard
way that takes some extra maintenance by your admins.
