Setting up NIS clients
You can use the Client Manager to configure or
unconfigure an NIS client. See
``The Client Manager interface''
for more information.
Alternatively, to establish a machine as an NIS client, do
Note that users can also use the
command to change their passwords in the NIS map,
but they can do so only if they do not have a password
already specified in /etc/shadow (see
Also, when the user has an entry in the local
file, running the passwd command only
affects the local client's environment.
In this case, you must run the yppasswd command
to change the NIS password maps:
Log in as the network administrator or the local administrator,
make backup copies of the /etc/passwd and /etc/group files
on the client,
and edit the original files by adding an entry such as ``+:'' to the end.
This ensures that processes consulting those files will
have access to the NIS maps.
to initialize the client.
specify the NIS domain name and the list of NIS servers for the client.
ps -ef | grep ypbind
to confirm that ypbind is running.
If it is not,
enter the /usr/lib/netsvc/yp/ypbind command from the command line.
Ensure that users on the client use the
to create their new passwords in the passwd maps.
Before they attempt to do this,
make sure the yppasswdd daemon is running
on the master server for the password map.
If the yppasswdd daemon is not configured to run
on the master server for the password map, you can enable it
as described in
``Starting the yppasswdd daemon''.
``Changing user passwords''.)
When a user types this command,
yppasswd prompts for the new password twice,
as does the local passwd command.
However, when the user has successfully responded,
yppasswd (or passwd when acting as such)
puts the new password in the
passwd.byname and passwd.byuid maps.
Users' NIS passwords can be different from the passwords
on their own machine.
If the yppasswdd daemon is not set to make and propagate
the newly modified password database immediately,
there may be a considerable time lag
between the time the user sets the new NIS password
and the time it takes effect.
Even when it is set,
map pushing is not instantaneous,
so if it takes a while it does not mean that the process failed.
