yppasswd


NAME
     yppasswd - change your network password in the NIS database

SYNOPSIS
     yppasswd [username]


DESCRIPTION
     The yppasswd utility changes the network  password   associ-
     ated  with the user username in the Network Information Ser-
     vice (NIS) database. If the user has done a keylogin(1), and
     a  publickey/secretkey  pair  exists for the user in the NIS
     publickey.byname map, yppasswd also re-encrypts the  secret-
     key with the new password. The NIS password may be different
     from the local one on your own machine.


     yppasswd prompts for the old  NIS password, and then for the
     new one. You must type in the old password correctly for the
     change to take effect. 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 charac-
     ters 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; superuser  on  the  root  master
     will not be prompted for the old password, and does not need
     to follow password construction requirements.


     The NIS password daemon, rpc.yppasswdd must  be  running  on
     your  NIS  server  in  order  for  the  new password to take
     effect.

SEE ALSO
     keylogin(1),  login(1),  NIS+(1),  nispasswd(1),  passwd(1),
     getpwnam(3C),         getspnam(3C),        secure_rpc(3NSL),
     nsswitch.conf(4), attributes(5)

WARNINGS
     Even after the user has  successfully  changed  his  or  her
     password  using  this command, the subsequent login(1) using
     the new password will be successful only if the user's pass-
     word  and  shadow  information  is  obtained  from  NIS. See
     getpwnam(3C), getspnam(3C), and nsswitch.conf(4).

NOTES
     The use of yppasswd is discouraged, as  it  is  now  only  a
     wrapper  around  the passwd(1) command, which should be used
     instead.  Using  passwd(1)  with  the  -r  nis  option  (see
     NIS+(1))  will  achieve  the  same results, and will be con-
     sistent across all the different name services available.

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