webservice authentication

[raol]

Hi

I would like to connect to a webservice with ws-security-
authentication. Is that possible with a php soap-client? I know that
http-authentication is no problem, but is there an implementation of
the ws-security (similar to wss4J for java) in php?

Http-authentication: $client = new SoapClient("som e.wsdl",
array("login" ="some_name" , "password" ="some_password "));

Ws-security:?

Thanks
Oliver
