Ajay, are you getting any messages printed to the screen when trying to su, and are there any messages in /var/adm/sulog relating to the attempts?

 

[bhawani123]

Yes.Please find error message which I got on the screen.

Have you checked whether the group listed for the user in /etc/passwd actally exists in /etc/group? The number and name of the group the user is a member of should be included in the latter.

If not, add it or change the user's group to a valid one and this will hopefully solve your problem. Good luck.

Hello KenCunningham,

This System is a NIS client and yesterday it was working fine.Even su - root is not acceptable.

Sorry NIS is outside my experience, but presumably the NIS server is up and hasn't been changed in any way since yesterday?

try changing your /etc/nsswitch.conf passwd line to just files, (remove the nis bit for the moment)

then give it a go again.

Hello mcrobiej,

I tried as you said.Firstly Removed the nis bit from /etc/nsswitch.conf file and restarted the daemon nfsd.
But I am getting same error message.
