NIS client couldn't log in

[Zhou, Rongx]

Hi, all       I recently setup NIS environment in linux boxes. I use Redhat 9.0. I think the environment set up properly with a NIS master , a NIS slave and a NIS client.  From the NIS client machine I type the ypcat passwd, I can see the newly added user accounts. But I can’t log in using this testing account through ssh. Can anyone give me advice? Thanks a lot.
