YPPASSWD(1)         UNIX Programmer's Manual          YPPASSWD(1)



NAME
     yppasswd - change login password in yellow pages

SYNOPSIS
     yppasswd  [ name ]

DESCRIPTION
     _Y_p_p_a_s_s_w_d changes (or installs) a password associated with
     the user _n_a_m_e (your own name by default) in the yellow
     pages.  The yellow pages password may be different from the
     one on your own machine.

     _Y_p_p_a_s_s_w_d prompts for the old yellow pages password and then
     for the new one.  The caller must supply both.  The new
     password must be typed twice, to forestall mistakes.

     New passwords must be at least four characters long if they
     use a sufficiently rich alphabet and at least six characters
     long if monocase.  These rules are relaxed if you are
     insistent enough.

     Only the owner of the name or the super-user may change a
     password; in either case you must prove you know the old
     password.

SEE ALSO
     passwd(1), ypfiles(5), yppasswdd(8C)

BUGS
     The update protocol passes all the information to the server
     in one rpc call, without ever looking at it.  Thus if you
     type in your old password incorrectly, you will not be noti-
     fied until after you have entered your new password.
