How to use sudoer ? FC5

[EYPO]

Hi.

I've have been trying to make easy sudoer

I (mike) run software called starting.pl where are one line:

system("sudo -u pete /home/mike/application.pl");

So I want to change to user pete and run the application which locates in my folder.

And here are sudoers file:

mike trinity= (pete) NOPASSWD: /home/mike/application.pl

So here I let user mike to change to user pete (WITH NO PASSWORD QUESTION) and then I let him to run application which is in my folder.

Why this wont work ?

When I run this application called starting.pl system always ask me to write the password ?
Why it ask met to write password? In my sudoer file I told to not ask the password ?

GIven your user is called "pete", then you should have a line like that (for this no password thing to work):

pete        ALL=(ALL)       NOPASSWD: ALL

in /etc/sudoers
