NAME

yppasswd − NIS password file

SYNOPSIS

/etc/yppasswd

DESCRIPTION

Create the Network Information Service (NIS) password map with this text file.  The format for /etc/yppasswd is the same as for the /etc/passwd file described in passwd(5). 

The text file for the NIS password map is stored in the /etc/passwd file on the NIS master of an NIS domain.  Other systems in a domain can also have a local /etc/passwd file.  The local file is accessed first by programs such as passwd(1), and if it contains a line beginning with the character ‘+’, the NIS map will be accessed. 

The local /etc/passwd file can specify users that are not available on a network-wide basis.  This implies that the NIS master cannot use the local /etc/passwd file to specify users that are to be known only to the local system.

NOTES

The Network Information Service (NIS) was formerly known as Yellow Pages (YP).  The functionality of the two remains the same; only the name has changed.  The name Yellow Pages is a registered trademark in the United Kingdom of British Telecommunications plc, and may not be used without permission.
