__soapCall return the authorization error - soap-client

Question

I am trying to work upon a soap request and it is returning me the auth failure. So, I tested the SOAP request in SOAP UI tool and found that it gives the expected output. I am doing something wrong in my coding.
/*create headers*/
$param= new SoapVar(array('Authorization' => $username,'password'=>$password), SOAP_ENC_OBJECT);
$header = new SoapHeader('ns1', 'Authorization', $param,false);
$client->__setSoapHeaders($header);
Make a call
try{ $id=$client->__soapCall('methodname',array('filename'=>$filename,'contents'=>base64_encode($content));
echo "Received a id:".$id;
echo '<pre>';
var_dump($client->__getLastRequestHeaders());
var_dump($client->__getLastRequest());
}
catch(SoapFault $e){
echo "Exception\n";
var_dump($e);
}
The request header as follow
string(207) "POST /services/refresh HTTP/1.1
Host: cpanel.myproject.com
Connection: Keep-Alive
User-Agent: PHP-SOAP/5.2.11
Content-Type: text/xml; charset=utf-8
SOAPAction: ""
Content-Length: 1410
In SOAP UI the Headers I notice there is following line as well
Thu Oct 20 13:41:37 IST 2011:DEBUG:>> "Authorization: Basic XXXX [\r][\n]"
I am just trying to add this header inside my soapCall any idea how can I do this...
Regards

Here is an example of call with header :
ini_set("soap.wsdl_cache_enabled", "0");
$httpsheader = new myHeader();
$header = $httpsheader->getHeader();
try
{
parent::__construct($wsdl, $header);
}
catch (Exception $e)
{
$this->_handleError($e);
}
class myHeader
{
function myHeader()
{
$this->header = array(
'proxy_host' => $proxy_host,
'proxy_port' => (int)$proxy_port,
'proxy_login' => $proxy_login,
'proxy_password' => $proxy_pass,
'login' => $merchantID,
'password' => $accessKey,
'style' => SOAP_DOCUMENT,
'trace' => 1,
'use' => SOAP_LITERAL);
}
function getHeader()
{
return $this->header;
}
}
