YPPASSWDD(8C)                                                    YPPASSWDD(8C)



NAME
       yppasswdd, rpc.yppasswdd - server for modifying NIS password file

SYNOPSIS
       /usr/etc/rpc.yppasswdd  filename  [  adjunct_file  ]  [  -nogecos  ]  [
       -noshell ] [ -nopw ] [ -m argument1 argument2 ...  ]

AVAILABILITY
       This program is available with  the  Networking  software  installation
       option.  Refer to for information on how to install optional software.

DESCRIPTION
       yppasswdd  is  a  server  that  handles  password  change requests from
       yppasswd(1).  Unless an adjunct_file is specified, it changes  a  pass-
       word  entry  in  filename,  which  is  assumed  to  be in the format of
       passwd(5).  filename is the password file that provides the  basis  for
       the  passwd.byname  and passwd.byuid maps.  This should not be confused
       with the servers /etc/passwd file which controls access to the  server.
       In particular this file should not contain an entry for the super user.

       If an adjunct_file is specified or /etc/security/passwd.adjunct exists,
       this file will be changed instead of the filename.  An entry  in  file-
       name  or adjunct_file will only be changed if the password presented by
       yppasswd(1) matches the encrypted password of that entry.

       If the -noshell -nogecos or -nopw options are given then  these  fields
       may not be changed remotely using chfn, chsh, or passwd(1).

       If the -m option is given, then after filename or adjunct_file is modi-
       fied, a make(1) will be performed in /var/yp.  Any arguments  following
       the flag will be passed to make.

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

EXAMPLE
       If  the  NIS  password  file  is stored as /var/yp/passwd, then to have
       password changes propagated immediately, the server should  be  invoked
       as

                     /usr/etc/rpc.yppasswdd     /var/yp/passwd    -m    passwd
                     DIR=/var/yp

FILES
       /var/yp/Makefile
       /etc/security/passwd.adjunct
       /etc/rc

SEE ALSO
       make(1),   yppasswd(1),   passwd(1),   passwd(5),    passwd.adjunct(5),

NOTES
       The password file specified to rpc.yppasswdd may not be a link.

       The  Network Information Service (NIS) was formerly known as Sun 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
