Project & Env - I'm migrating a legacy server from A->B. It is CentOS4 i686. The code base seems to be a very organically grown mix of libs and modules all over the place. Oh, and it uses Apache 1. Giving the code and deps a much needed update is not in the scope of the project. All I am tasked with is moving from A->B which happens to be a physical server at data center A, to a virtual server at data center B. The server's primary function is a user login page (cookies) that redirect you to another server where actual user accounts live. Let's call that server C.

I have Server B up and running and most of the software is working except for one big gotcha. If I attempt to use the log in code on http (port 80) I am happily redirected to my account on server C. If I attempt to use the log in code on https (port 443) I can load server B's web page fine, but submitting the page gives me this error (from CARP).

The Error

501 (Not Implemented) Protocol scheme 'https' is not supported (Crypt:
+:SSLeay not installed)

LWP will support https URLs if the Crypt::SSLeay module is installed.

I've spent the last few hours.. OK days.. trying to figure this out. First off let me clarify that Crypt::SSLeay is installed. Twice. Here are the two dirs

• /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi/Crypt/SSLeay
• /usr/local/ray/lib/perl5/site_perl/5.8.5/i686-linux/Crypt/SSLeay

The first dir install was done via CPAN. And the second was copied from server A. Note that 99% of the server install base lives in under the /usr/local/ray root directory. Also note that Server A does not have a CPAN install of Crypt::SSLeay, it only has the one under /usr/local/ray.

I've attempted to force the login code to use Crypt/SSLeay with "use lib". I looked into recompiling from source. So far no joy. Here are the relevant sections of code on the login page.

Abbreviated code

#!/usr/bin/perl

use strict;

use lib '/usr/local/ray/www/site_perl';
use Apache::Constants qw(:common);
use CGI qw(:standard);
use CGI::Carp;
use LWP::UserAgent;

my $cgi = new CGI;
my %p = $cgi->Vars;

$p{credential_0} =~ s/^\s+|\s+$//g;

my $server= 'server_c';
my $domain= 'company.com';

## Set protocol based on what the user wants
## some might use http 
my $protocol = 'http';

## And for https...
if ( $ENV{HTTP_REFERER} =~ /^https:/ ) {
    $protocol = 'https';
}

## This is the server that the user will be redirected to
my $url = "$protocol://$server.$domain";
my $dest = '/users/';
my $creds = "credential_0=$p{credential_0}&credential_1=$p{credential_
+1}&destination=$dest";

my $ua = LWP::UserAgent->new(ssl_opts => { verify_hostname => 0 });

## Post the credentials
my $req = HTTP::Request->new(POST => "$url/LOGIN");
$req->content_type('application/x-www-form-urlencoded');
$req->content($creds);

## Get the response
my $res = $ua->request($req);

## Change location to their server
$res->header( 'Location' => "$url/users/" );

## Print to browser
print $res->as_string;

Any advise is appreciated.
