I've written a small perl program to execute a series of Root level commands, and give me the result. It works great when I run it from a terminal, but I tried moving it into my cgi-bin to talk to it from a web page, and I keep getting null responses from the execution commands.

So I call it with things like:
my $result = &SU("/bin/echo","hi");

And when I run from console, I get the result, but when I run from apache, I get null and no system errors.

IS this because apache isn't a sudoer? OR something along those lines, where I can't actually execute a sudo while running as the apache user?

Anyone got any enlightenment on how I can make this work? 
#!/usr/bin/perl -w
use strict;

print CGI::header();  
my $result = &SU("/bin/echo","hi");
print $result;
exit;

sub SU(){
my $app = $_[0];
my $args = $_[1];

  $su = Sudo->new(
                  {
                   sudo         => '/usr/bin/sudo',
                   username     => "root", 
                   password     => "password",
                   program      => $app,
                   program_args => $args
                  }
                 );
   
  $result = $su->sudo_run();
  if (exists($result->{error})) { 
        print "Error is $result";
     }
   else {
    if ($result->{stdout}eq""){
        warn();
        print "Null response";
    }
    return ($result->{stdout});
     }
}
