yppasswd(1M)                                                   yppasswd(1M)

NAME
     yppasswd - change global user password

SYNOPSIS
     yppasswd [-a] [globaluser]

DESCRIPTION
     Just as you change the password for a user name with the passwd(1)
     command, you can change the password of a global user with the
     yppasswd command. The yppasswd command manipulates the yppasswd source
     file of the NIS master. The yppasswd source file is normally
     /etc/yppasswd but can be given a different name [see yppasswdd(1M)].

OPTIONS
     -a   The modified global password is entered locally in the
          /etc/shadow file, provided that the new procedure for global user
          administration is selected and the replacement of the password is
          permitted with this procedure.

     If the -a option is not specified or if the old procedure for global
     administration was selected, the new password is only accepted in the
     local /etc/shadow file when the next periodic update takes place. Glo-
     bal passwords cannot be changed locally with passwd.

     Using global passwords reduces security, because all users can read
     the encoded passwords with ypcat passwd.byname - and can therefore
     also decode them.

FILES
     /etc/default/inet

     /var/yp/pwpattern

     /etc/passwd.local
