I don't know about which program you are talking (no references or
quotes in your mail), however, maybe your program can be executed by
the user but it must be root to do what it does. E.g. you can execute
xscanimage as normal user for scanning with parport scanners but it
won't help because /dev/port access needs root access.

You could use the "setuid" bit for running the program with root
privileges (chmod u+s /path/to/program) but this is dangerous and
won't work with shell scripts.

You can also use "sudo" to give certain users the permission to use
specific programs as root.

Bye,
