What does “visudo: Warning: Cmnd_Alias `NOPASSWD' referenced but not defined,” mean?

Question

I am editing the file sudoer using the visudo command. When I am done saving the file this warning appears.

visudo: Warning: Cmnd_Alias `NOPASSWD' referenced but not defined

I am not able to remotely execute a particular file as a non root user. I think this warning might have something to do with it.

How do I resolve this warning?

EDIT: It is actually NOPASSWD

Answer 1

Like Paulo Scardine said, it is difficult to tell without looking at sudoers file.

The warning is still there but the reason I was not able to sudo remotely is because I did not put

Defaults !visiblepw

We need to either turn it off or turn it on but we cannot do without it.
