The MINUID and MINGID allow to create passwd.by* only with account which UID are equal or higher than MINUID and group.by* only with groups which GID are equal or higher than MINGID.

...or `ypcat`, or however you get a flatfile version of /etc/passwd.

You don't need to copy
/var/yp/master.passwd to edit it; just make the change and run "make".

So I would change the original /etc/master.passwd ?????? Is that OK, it looks like it's not.

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.
