Tagging HTTP Basic Auth to outbound packets

Hello,
I’m struggling to get simple HTTP basic authentication be “tagged” to http endpoints (for outbound communications).  I’m using 2.0
I followed this page: http://mule.mulesource.org/display/MULE2USER/Mule+Security

And ended up with
  <http:endpoint name="WebServiceGateway" host="127.0.0.1" user="123" password="password" remoteSync="true" port="8080" path="/echo" method="POST">
    <property key="Content-Type" value="text/xml"/>
     <security-filter className="org.mule.extras.acegi.filters.http.HttpBasicAuthenticationFilter">
        <properties>
            <property name="realm" value="my-realm"/>
</properties>
    </security-filter>
  </http:endpoint>


I get a schema issue;

23/07 02:56:23:234 main DEBUG - register ref:WebServiceGateway.17: org.mule.config.spring.factories.OutboundEndpointFactoryBean

I have also tried to use http-security-filter from acegi but with no success.

My question is; Is this is correct way to attach credential to http outbound packets via the http:endpoint?  If so, it is simply a schema issue?

Any assistance would be greatly appreciated.

Thanks,

Ian.
