Use 'vipw' to edit /etc/passwd safely.
However, the point of NIS is to provide a network-based source of users
which are in addition to the users in the local /etc/passwd database.
On your YP/NIS master server, cd to "/var/yp" and do a make. That will
propogate updated versions of the passwd.foo NIS maps to the NIS clients.
