  NAME

    yppasswd - Changes a login password in a Network Information Service (NIS)
    database

  SYNOPSIS

    yppasswd [name]

  DESCRIPTION

    The yppasswd command changes or installs a password associated with the
    user name (the default name is the current user) in the Network
    Information Service (NIS) database.  The NIS password may be different
    than the one on the local machine.

    The yppasswd command prompts for the old NIS password and then for the new
    one.  The user must supply both.  The user receives a verification prompt
    for the new password.  New passwords must have at least four characters if
    they use a sufficiently-rich alphabet (uppercase, lowercase, and
    nonalphabetic characters) or at least six characters if monocase (all
    uppercase or all lowercase).

    Only the name owner or superuser can change a password; in either case the
    old password must be supplied.

  CAUTIONS

    The update protocol passes all information to the server in one Remote
    Procedure Call without looking at it.  Thus, if the old password is
    entered incorrectly, notification is not sent until after the new password
    has been entered.

  EXAMPLES

    1.  To change the password for user smith in the NIS database, enter from
        the superuser prompt:

        yppasswd smith


    2.  To change the NIS database password for your own login, enter:

        yppasswd


  DIAGNOSTICS

    Not in password file
           The specified login name has no entry in the local /etc/passwd
           file.
