NAME

       yppasswdd, rpc.yppasswdd - server daemon for modifying the Network Information Service (NIS) password file

SYNOPSIS

       /usr/sbin/rpc.yppasswdd file [-m arg1 arg2...]

DESCRIPTION

       The yppasswdd daemon is a server that handles password change requests from yppasswd(1). It changes a password entry in the specified file,
       which is assumed to be in the same format described in passwd(4).  An entry in file will be changed  only  if  the  password  presented	by
       yppasswd(1) matches the encrypted password of that entry.

       If  the -m option is given, then after file is modified, a make(1) will be performed in /var/yp. Any arguments following the option will be
       passed to make. The -m option should be set only at a NIS master server machine.

       This server is not run by default, nor can it be started up from inetd(8).  If it is desired to enable remote  password	updating  for  the
       NIS, then an entry for yppasswdd should be put in the /sbin/init.d/nis file of the host serving as the master for the NIS passwd file.

SECURITY NOTE

       When enhanced security is installed and NIS is used to distribute the protected password authentication database, the yppasswdd daemon man-
       ages writes to that database.  A strict C2 security     policy, which is optionally configurable using  enhanced  security,  requires  each
       user  login or login failure to be recorded in the protected password authentication database.  These updates, in combination with password
       changes and system administration functions affecting user accounts, are coordinated by the daemon.

EXAMPLES

       If the NIS password file is stored as /var/yp/src/passwd, then to have password	changes  propagated  immediately,  the	server	should	be
       invoked as: /usr/sbin/rpc.yppasswdd /var/yp/src/passwd -m passwd DIR= /var/yp/src
