yppasswdd(1M)                                       yppasswdd(1M)



NAME
     yppasswdd, rpc.yppasswdd  -  handle  requests  to  change  a
     password served by the Network Information Service (NIS)

SYNOPSIS
     rpc.yppasswdd file [-m make-arg...]

ARGUMENTS
     file Specifies the name of a file, which must be in the
          format described in passwd(4), to be updated. The usual
          value of file is /etc/passwd.  Some NIS master servers
          maintain a global NIS password file in /etc/yp and use
          /etc/passwd for local login sessions. For such master
          servers, the value of file is the absolute pathname of
          the global password file.

     -m make-arg...
          Causes yppasswd to change the password in the source
          file and run make.  You can supply one or more make-arg
          arguments to customize the way yppasswd runs make.  See
          ypmake(1M) for details.

DESCRIPTION
     yppasswdd is a daemon that runs on an NIS master server to
     handle requests made by yppasswd to change a user's
     password.  The yppasswd command prompts the user for the old
     and new password, just as the passwd command does, and sends
     the information to yppasswdd, which makes the change in the
     global password source file only if the old password matches
     the value already in the password file.

     To enable yppasswdd, you should add an entry to the
     /etc/inittab file of the NIS master server for the domain.

EXAMPLES
     This entry in /etc/inittab enables yppasswdd, using the
     /etc/passwd file as the source file, and runs make to
     rebuild the password maps and to notify the slave servers of
     the change:

        nfs9:2:once:/usr/etc/rpc.ypasswdd /etc/passwd -m passwd

     This entry, which should be made on a single line, enables
     yppasswdd, using the /etc/yp/src/passwd file as the source
     file:

        nfs9:2:once:/usr/etc/rpc.yppasswdd /etc/yp/src/passwd \
        -m passwd DIR=/etc/yp/src

     This entry enables yppasswdd so that it modifies the
     password file but does not run make to update the maps or
     notify the slave servers of the change:

yppasswdd(1M)                                       yppasswdd(1M)



        nfs9:2:once:/usr/etc/rpc.ypasswdd /etc/passwd

     You might want to run yppasswdd in this way to avoid
     performance degradation if users change their passwords
     frequently. If you enable yppasswdd in this way, make sure
     that the slave servers run ypxfr regularly so that their
     maps are updated.

FILES
     /etc/yp/Makefile
          File that tells make how to rebuild the maps
     /usr/etc/rpc.yppasswdd
          Executable file
