Webservice connector error(Authentication Failed)

Hi Wmusers,
we are using webmethods 8.2
I am facing webservice connector authentication error…
Client provided wsdl document… by using that wsdl document we created webservice consumer.while running webservice connector we are getting authentication error…

In the same way we tested wsdl by using saop-ui… we got response…it seems every thing is fine… but why we are getting this error…

We provided username,password povided by the client…

Can any body help me on this…it’s urgent…Hope for the positive response…

hope you are not missing to pass value in auth document during consumer invoke.
