> We are on Jboss 6.1.0 the version of CXF is 2.6.6 and has a bug when delegation is used:
> AbstractSpnegoAuthSupplier (v 2.6.6) has this method call:
>    [...]
>       return getToken(delegatedCred == null ? authPolicy : null, context);
>    [...]
> here if we have delegatedCred with a value the statment passes null to the method:
>    private byte[] getToken(AuthorizationPolicy authPolicy,
>                             final GSSContext context) throws GSSException,
>         LoginException {
>         
>         String contextName = authPolicy.getAuthorization();
>         if (contextName == null) {
>             contextName = "";
>         }
>         
>       [...]
>     }
> if authPolicy is null (our case) the method throws a NullPointerException.
> So I got the fixed AbstractSpnegoAuthSupplier and SpnegoAuthSupplier from cxf 2.7.1 copied/renamed
in my project and programmatically set on HTTPConduit:
>   [...]
>    HTTPConduit http = (HTTPConduit) client.getConduit();
>    http.setAuthorization(authorization);
>    http.setAuthSupplier(new CustomSpnegoAuthSupplier());
>   [...]
> And now it works fine.
