NAME
      rpc.nispasswdd, nispasswdd - NIS+ password update daemon
 


SYNOPSIS
      /usr/sbin/rpc.nispasswdd [ -a attempts ]  [ -c minutes ]   [
      -D ]  [ -g ]  [ -v ]
 


DESCRIPTION
      rpc.nispasswdd daemon is an ONC+ RPC service  that  services
      password  update requests from nispasswd(1) and yppasswd(1).
      It updates password entries in the NIS+ passwd table.
 
      rpc.nispasswdd is normally started  from  a  system  startup
      script  after  the  NIS+  server  (  rpc.nisd(1M))  has been
      started. rpc.nispasswdd will determine whether it is running
      on  a  machine  that is a master server for one or more NIS+
      directories.  If it discovers that the host is not a  master
      server,  then  it will promptly exit. It will also determine
      if rpc.nisd(1M) is running  in  NIS(YP)  compatibility  mode
      (the  -Yoption)  and  will register as yppasswdd for NIS(YP)
      clients as well.
 
      rpc.nispasswdd  will  syslog  all  failed  password   update
      attempts,  which  will  allow  an administrator to determine
      whether someone was trying to "crack" the passwords.
 
      rpc.nispasswdd has to be run by a superuser.
 


OPTIONS
      -a attempts
            Set the maximum number of attempts allowed to  authen-
            ticate  the  caller  within  a password update request
            session.  Failed  attempts  are  syslogd(1M)  and  the
            request  is  cached  by  the daemon. After the maximum
            number of allowed attempts the daemon severs the  con-
            nection to the client. The default value is set to 3.
 
      -c minutes
            Set the number of minutes  a  failed  password  update
            request  should  be  cached by the daemon. This is the
            time during which if the daemon receives further pass-
            word update requests for the same user and authentica-
            tion of the caller fails, then the daemon will  simply
            not respond. The default value is set to 30minutes.
 
      -D    Debug. Run in debugging mode.
 
      -g    Generate DES credential. By default the DES credential
            is not generated for the user if they do not have one.
            By specifying this option, if the user does not have a
            credential,  then  one  will be generated for them and
            stored in the NIS+ cred table.

      -v    Verbose. With this option, the daemon sends a  running
            narration  of  what  it is doing to the syslog daemon.
            This option is useful for debugging problems.
 
 EXIT STATUS
      0     success
 
      1     an error has occurred.
