NAME
      yppasswd - change your network password in the NIS database
 


SYNOPSIS
      yppasswd [ username ]
 


DESCRIPTION
      yppasswd changes the network password  associated  with  the
      user  username  in  the  Network  Information Service (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 dif-
      ferent  from  the  local  one  on  your  own  machine.   Use
      passwd(1)  to  change  the password information on the local
      machine, and nispasswd(1) to change the password information
      stored  in  Network  Information  Service  Plus,  Version  3
      (NIS+).
 
      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.

 User Commands                                         yppasswd(1)
 
 
 
 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 link
      to  the  passwd(1)  command,  which  should be used instead.
      Using passwd(1) with the -r nis option will achieve the same
      results,  and  will  be  consistent 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.
