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.

NOTES

     NIS+ might not  be  supported  in  future  releases  of  the
     SolarisTM  Operating Environment. Tools to aid the migration
     from NIS+ to LDAP are available in the Solaris  9  operating
     environment.      For      more      information,      visit
