nispasswdd(1M)
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.

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
