pw by default works on the local /etc/passwd, not the yp passwd 
database. I suggest reading about the -y option in the manpage:

-y path

This sets the pathname of the database used by NIS if you are not 
sharing the information from /etc/master.passwd directly with NIS. You 
should only set this option for NIS servers.
