Another YP question

[Waldher, Travis R]

"At this point, make sure that /etc/passwd and /etc/group have
been edited so that when the NIS is activated, the data bases you
have just created will be used, instead of the /etc ASCII files."

What do I need to do to guarantee this.  I've read something about a
"+::" entry, but not sure how to implement it.  How do I test it to
verify it is working?

More importantly, did I just make sense? LOL
