Description:
------------
I am trying to connect PHP to Bricolage (a CMS) using SOAP.    
Bricolage doesn't seem to have a WSDL, but they do have a    
SOAP interface.    
    
In order to make a request, I must first authenticate them   
make my request. This requires changing namespaces.   
Unfortunately, using a uri parameter when calling   
__soapCall doesn't seem to change the namespace, as I would   
expect.   
  
The code I've included is simplified to show just the  
error, so you don't see me using the default namespace. 

Reproduce code:
---------------
$opts = Array("location" => "http://localhost:8080/soap", "uri" => "http://bricolage.sourceforge.net/Bric/SOAP/Auth", "trace"    => 1);

$client = new SoapClient(null, $options);

$newNS = "http://bricolage.sourceforge.net/Bric/SOAP/Story";

try {
  $ret = $this->__soapCall("list_ids",Array(),Array("uri" => $newNS));
} catch (Exception $e) {
  print $client->__getLastRequest();
}


Expected result:
----------------
