sudo not working for suse vm created on azure platform

Hi,

I have created the Suse Vm(SUSE Linux Enterprise Server 11 SP3) using Azure portal.

But sudo command is not working on it.

When I tried to use sudo command it is asking me the root user's password.

But sudo is woking on suse vm that I had created before.

Can you please suggest what should be the problem?

Thanks,

Abhijit
