Can't change NIs passwd at client end
 

Hi! Please help!
Currently I am setting up a Lan using Linux 9 with one NIS Master , one NIS slaves and a number of NIS clients.

Recently, I have encountered one problem at client - unable to change the NIS password.
The following error messages were collected :

[wanch@c103]$ passwd
Changing password for user wanch.
Changing password for wanch
(current) UNIX password:
New password:
Retype new password:
Error while changing NIS password.

The password has not been changed on s2.
passwd: Failed preliminary check by password service

[wanch@c103]$ yppasswd
Changing NIS account information for wanch on s2.
Please enter old password:
Changing NIS password for wanch on s2.
Please enter new password:
Please retype new password:
Error while changing the NIS password.
The NIS password has not been changed on s2.

S2 is my NIS master. The service yppasswd is running fine at server end and I can change password at server. I have tried to restart the yp* services at both server and client ends but still unable to find out the fault.

Thanks.

is yppasswd running on both the NIS Master & Slave?

Thanks for the reply.

Yes, I have yppasswdd at both NIS master and slave

These are services found in my NIS master s2 and NIS slave s1

I am able to login at client end as non-root user but unable to change my nis password.
The client seems to fail to send the PW to s2.

I'm having a similar problem. I setup NIS on Redhat 5.1 and for all other user's it seems okay but when I try to change my own password on a NIS client it says the following...

NIS CLIENT....
[jglenton@server ~]$ passwd
Changing password for user jglenton.
Changing password for jglenton
(current) UNIX password:
New UNIX password:
Retype new UNIX password:
NIS password could not be changed.
passwd: Failed preliminary check by password service
[jglenton@server ~]$

This is the result on the NIS Master.

NIS MASTER....
[root@server2 ~]# yppasswd jglenton
Changing NIS account information for jglenton on server2.random.com.
Please enter root password:
Changing NIS password for jglenton on server2.random.com.
Please enter new password:
Please retype new password:
Error while changing the NIS password.
The NIS password has not been changed on server.random.com.
[root@server2 ~]#

Any help would be very appreciated...!

Thanks
James
