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 authenticate 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 connection 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 password update requests for the same user and authentication 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.

available in the Solaris 9 operating environment. For more information, visit http://www.sun.com/directory/nisplus/transition.html.
The rpc.nispasswdd service is managed by the service management facility, smf(5), under the service identifier:
svc:/network/rpc/nisplus:default
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
