I'm working on an app that requires root privileges, I have created an bluehead.sudoers file containing:

user ALL = NOPASSWD: /opt/bluehead/bin/bluehead

i have also included a postinst file containing:

#!/bin/sh

update-sudoers

exit 0

the app executable is installed to /opt/bluehead/bin/
app name = bluehead

When i install this app on my device using the Qt SDK it still asks for password when i try sudo bluehead in the installation directory
ls - l on the executable returns -rwxr-xr-x

I'm developing on Qt SDK 1.1.4

What I'm I missing out? Any help appreciated (I'm about to start pulling my hair out)
