NAME

yppasswd  -  YP password file

SYNOPSIS

/etc/yppasswd

DESCRIPTION

This is the text file used to create the YP password map on the Sun386i.  It has the same format as the /etc/passwd file described in passwd(5). 

The text file for the YP password map is stored in the /etc/passwd file on the YP master of a YP domain.  Other systems in a domain (besides the YP master) can also have a local /etc/passwd file.  The local file is accessed first by programs such as passwd(1), and if a line begins with a ‘+’ the YP map is also accessed.  The local /etc/passwd file on a machine can be used to specify users that are not available on a network-wide basis. 

This strategy implies that the YP master cannot use the local /etc/passwd file to specify users that are to be known only to the local system.  This is because the local /etc/passwd file on the YP master is the actual text file used to create the YP password map.  The Sun386i solves this by allowing the /etc/passwd file on the YP master to be used locally, and using /etc/yppasswd as the text file used for creating the YP password map.  This also allows the re-creation of /etc/yppasswd on each slave server so it can more easily become a master.
