Help with SOAP::LITE

slgilley has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying -- and failing -- to write a simple test app using SOAP::LITE. (I've also tried SOAP::WSDL, but further reading made me believe that it really isn't required for what I want to do.)

I'm new to SOAP, new to these packages, and new to what I'm trying to do, so I don't know how many things I'm doing wrong, but I think I've distilled it down to a few lines of code that seem to me should work. I think the essential problem is in authentication, but I've also given some thought that it may be the way I'm trying to call the service manager routine via SOAP.

Here's the first method I found:

#!/usr/local/perl5/bin/perl
use SOAP::Lite+trace => 'all';

$USER = "working_user_name";
$PASS = "working_password";

sub SOAP::Transport::HTTP::Client::get_basic_credentials {
        print "###\n";
        print "###\n";
        print "### Authenticating...\n";
        print "###\n";
        print "###\n";
        return $USER => $PASS;
}


my $soap = SOAP::Lite->new(proxy => 'http://<hp_service_manager>:13080
+/SM/7/ws');
$soap->default_ns('http://schemas.hp.com/SM/7');
my $som = $soap->call('RetrieveList');
die $som->faultstring if ($som->fault);
print $som->result, "\n";

And the LWP method I tried:

#!/usr/local/perl5/bin/perl
use SOAP::Lite+trace => 'all';
use LWP::UserAgent;
use LWP::Debug;
LWP::Debug::level('+');

$USER = "working_user_name";
$PASS = "working_password";

my @ua_args = (keep_alive => 1);
my @credentials = ($SERVICE_NS, "", $USER, $PASS);
my $schema_ua = LWP::UserAgent->new(@ua_args);
$schema_ua->credentials(@credentials);

my $soap = SOAP::Lite->new(proxy => 'http://<hp_service_manager>:13080
+/SM/7/ws', @ua_args, credentials => \@credentials);
$soap->default_ns('http://schemas.hp.com/SM/7');
my $som = $soap->call('RetrieveList');
die $som->faultstring if ($som->fault);
print $som->result, "\n";

Can anyone help? This is becoming extremely frustrating. I can't find examples, or if I can, they aren't completely clear to me because I'm not sure I fully understand things like "endpoint", "namespace", "uri", and "urn".

Edit: The issue is that no matter what I do I get a "not authorized" return. No live URLs, as this is a business, and even assuming I gave you one, you couldn't get here. (Not to mention inviting people to try breaking in would probably get me fired.) It's an HP Service Manager installation. I'll provide the WSDL entry for what I'm trying to do. I doubt it's useful.

<soap:operation soapAction="RetrieveList" style="document"/>
<input>
<soap:body use="literal"/>
</input>
<output>
<soap:body use="literal"/>
</output>
</operation>

While there is a lot more where this came from, this is the pertinent output, I believe:
