I think the title, sums up this one. I have a CGI script that is calling another script via system(), specifically, my $ERR = system("/usr/bin/sudo /usr/local/nbin/verify.pl --username foo --password bar"). As you can guess, the verify.pl script verifies the provided password against the system password for the spec'd username. I use Authen::PAM for the process, and in the verify.pl script, I return the result

sub check_password { ## inquiry to PAM my $pamh = new Authen::PAM($service, $username, \&my_conv_func) or die "Error code during PAM init!\n"; ## grab return from auth process. other than 0 equals failure my $answer = $pamh->pam_authenticate; return $answer; }

However, it looks as though $ERR is always set to 0 since the system call is working.

How can I get the return from my verify.pl script to show up in the value of $ERR?

thanks! -c
