PHP and Web Services [JIVE]

Hello All, I am trying to make a web service call using SOAP and PHP to create a new community. I keep on receiving unauthorized exception. Please let me know what I forgot in my code here. How is it possible to send authentication headers in a SOAP call? I would appreciate if some one could post some code here to make things clear. Thanks CODE $sso_wsdl_url_getemail = " http://XXXXXXXX:8080/rpc/soap/CommunityService?wsdl";<http://xxxxxxxx:8080/rpc/soap/CommunityService?wsdl%22;> $client = new SoapClient($sso_wsdl_url_getemail, array( 'login' => "XXXXXX", 'password'=> "XXXXX", 'proxy_host' => "XXXXXXX", 'proxy_port' => 3128, 'exceptions' => 0, 'encoding' => "UTF-8", 'connection_timeout' => 60 )); $input = array(); $input['name'] = "Just A Small Test"; $input['disp'] = "Just Check it"; $input['desc'] = "Check it"; $result = $client->createCommunity($input); print_r($result);
