sudo su to an other user to run script

Question

I am trying to login as USER1 and switch user to USER2 and execute some scripts (100+ scripts, can't list them all out in the sudoer file one by one) as USER2

in the Sudoer file i have

   USER1 ALL=(USER2) NOPASSWD: ALL

When i run the following as USER1

  sudo su - USER2 -c "test.sh"

I get

Sorry, user USER1 is not allowed to execute '/bin/su - USER2 -c test.sh' as root

if i run

  sudo su - sassrv

I get

Sorry, user USER1 is not allowed to execute '/bin/su - USER2'

If i change the Sudoer file to

         USER1 ALL=(ALL) NOPASSWD: /bin/su - USER2

It will let me switch user, but i am still getting

Sorry, user USER1 is not allowed to execute '/bin/su - USER2 -c test.sh' as root

How can i achieve this?

Answer 1

You wanted to run test.sh as USER2 with sudo , but instead you run su as root.

su may in turn try to run test.sh as USER2, but that's beyond the scope and knowledge of sudo . From sudo 's point of view, the only thing you're doing is trying to run a command as root.

Instead, ask sudo to run test.sh as USER2 directly:

sudo -u USER2 test.sh

PS: sudo su in any context is a code smell that indicates a lack of understanding of what sudo is and does.
