How to run script as another user without password

Question

I have script sh that must be run as user2   However  this script can only be run under user1 in my application   I would like the following command to run   su user2 -C script sh   but be able to run without password   I also want this to be very restrictive  as in user1 can only run script sh under user2 and nothing else   I ve tried doing this with sudoers file and just got endlessly confused after hours of trying   If somebody can provide an explicit example of how this can be accomplished  instead of something generic like use sudoers   it would be greatly appreciated
