DESCRIPTION

The rpc.yppasswdd command is an NIS server that handles password change
requests from yppasswd.  It changes a password entry in file, which is assumed
to be in the format of passwd.  An entry in file will only be changed if the
password presented by yppasswd matches the encrypted password of that entry.

This server is not run by default, nor can it be started up from inetd.  If it
is desired to enable remote password updating for NIS, an entry for
rpc.yppasswdd should be put in the /etc/rc.nfs file of the host serving as the
master for the NIS passwd file of the current NIS domain.

Notes:

  1. This can be accomplished by uncommenting (removing the leading "#"
    characters from) lines found in the default /etc/rc.nfs file.

  2. If the NIS master host is a site in a TCF cluster, rpc.yppasswdd should
    only be started on that one host in the cluster which is the master.  This
    is already accounted for in /etc/rc.nfs by a check for the existence of the
    file /local/yp/<domain>/MASTER.

You can either choose to make the NIS password input file be /etc/passwd or
select another input file of the same format.  You would select an alternate
password input file, for instance, if you wanted to allow additional users to
log on to the master NIS host beyond those permitted to log on to other hosts
in your NIS domain.

To select an alternate NIS password input file, for example /etc/yp/passwd, you
should start up /etc/rpc.yppasswdd as follows:
