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.
