YPGROUP(5)

NAME
ypgroup - NIS group file

SYNOPSIS
/etc/ypgroup

AVAILABILITY

Available only on Sun 386i systems running a SunOS 4.0.x release or earlier. Not a SunOS 4.1 release feature.

DESCRIPTION

Create the Network Information Service (NIS) group map with this text file. This file has the same format as the /etc/group file described in group(5).

The text file for the NIS group map is stored in the /etc/group file on the NIS master of an NIS domain. Other systems in a domain (besides the NIS master) can also have a local /etc/group file. The local file is accessed first by programs such as groups(1), and if it contains a line beginning with the character `+', the NIS map will be accessed. The local /etc/group file can specify groups that are not available on a network-wide basis.

This implies that the NIS master cannot use the local /etc/group file to specify groups that are to be known only to the local system. Sun386i systems allow the /etc/group file on the NIS master to be used locally, creating the NIS group map from the /etc/ypgroup text file.
