/etc/passwd file to supplement entries that are
valid only locally.
User entries can be added from the NIS password map
by starting them with the token ``+''.
NIS entries for users have the following format:
The fields have the same meaning as for ordinary passwd(F) file entries except that there are no entries for the user or group IDs. That is, the UID and GID from the NIS entry are always used; they cannot be defined locally. Entries in the password, comment, directory, or program field override the corresponding value obtained from the NIS server.
The following entry inserts the entire NIS password file:

starting their passwd entries with ``-'' instead
