nis unable to login from the nis client

[Adithyan]

Hi friends,

I have a NIS server where I have exported my /home in rw mode to the NIS client. all the services are running for both server and client through automount I can see the /home in my NIS client. All the required daemons are running in both the nodes.

NIS server:

100007 1 udp 644 ypbind

But when I am trying to login from the NIS client its giving me access denied:

login as: test1
test1@testnode2's password:
Access denied
test1@testnode2's password:

Where test1 is the user created in NIS server.

I am able to change the password for the nis server :

[root@testnode2 init.d]# yppasswd test1
Changing NIS account information for test1 on testnode1.
Please enter root password:
Changing NIS password for test1 on testnode1.
Please enter new password:
Please retype new password:

The NIS password has been changed on testnode1.
Pls let me know whats wrong?

Thanks.

Shalom,

Check /var/adm/syslog/syslog.log on both systems.

See if the configuration files are compatible or if some firewall is blocking the needed ports.

what does ypmake on the master do?

You could try a couple of things:
- Check to see if the user has a login shell available to him
i.e. # getent passwd test1

- Restarting nscd (if running) might help on some older versions

- Check log messages for errors, could be a pam issue
