       yppasswd - change your network password in the NIS database

       yppasswd [username]

       The  yppasswd utility 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
       secretkey 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 suf‐
       ficiently  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; 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.

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

       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  password  and	 shadow information is
       obtained	 from  NIS.   See   getpwnam(3C),   getspnam(3C),   and	  nss‐

       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 consistent across all the different name services available.

       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.
