yppasswdd(8)


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 manages
  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

  /var/yp/Makefile
