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.

This option is useful for debugging problems.
