PHP consume a .net service - php

Question

So i have the following web service that is found on
http://screencast.com/t/y8qM8hRDu
These are my trials and results:
Try 1:
$api_target = "http://www.xyz.co/service1.svc?wsdl"
$soap_options["location"] = $api_target;
$soap_options['trace'] = TRUE;
$soap_options['cache_wsdl'] = WSDL_CACHE_NONE;
$soap_options['style'] = SOAP_RPC;
$soap_options['use'] = SOAP_ENCODED;
$soap_options['soap_version'] = SOAP_1_2;
$client = new SoapClient($api_target,$soap_options);
$result = $client->Login(array("parameters" => $user));
Response 1:
The SOAP action specified on the message, '', does not match the HTTP SOAP Action, 'http://tempuri.org/IService1/Login'.
Try 2: added SOAPaction header
$actionHeader = new SoapHeader($api_target,'SOAPAction','http://tempuri.org/IService1/Login');
$client->__setSoapHeaders($actionHeader);
$client = new SoapClient($api_target,$soap_options);
$result = $client->Login(array("parameters" => $user));
Response 2::
Bad Request

$api_target = "http://www.xyz.co/service1.svc";
$api_url = $api_target."?wsdl";
$action = "http://tempuri.org/IService1/Login";
$soap_options["location"] = $api_target;
$soap_options["uri"] = $api_url;
$soap_options['trace'] = TRUE;
$soap_options['cache_wsdl'] = WSDL_CACHE_NONE;
$soap_options['style'] = SOAP_DOCUMENT;
$soap_options['use'] = SOAP_LITERAL;
$soap_options['soap_version'] = SOAP_1_2;
$actionHeader[] = new SoapHeader('http://www.w3.org/2005/08/addressing','Action',$action , true);
$actionHeader[] = new SoapHeader('http://www.w3.org/2005/08/addressing','To',$api_target ,true);
$client = new SoapClient($api_url,$soap_options);
$client->__setSoapHeaders($actionHeader);
$result = $client->__soapCall('Login',array($user));;
