As Matt has pointed out, this is the proper way to get the wsdl using http basic 
authentication.  The default transport already is HttpAuthenticated so you simply need to 
pass the username and password in the Client constructor.

If this does not work then maybe your server does not implement RFC-2617 (as described 
here: http://en.wikipedia.org/wiki/Basic_access_authentication) properly in which case I 
can describe the workaround.
