We are running a set of WCF services over HTTPS and using the ws2007FederationHttpBinding binding to authenticate against a STS.
Now we need to add a dual/duplex service using the same authentication technique. Know Your Binding Options states that only wsDualHttpBinding is available for duplex services. Can i use it together with my STS and if yes does somebody know how to configure it?

No, and if outward facing, dual binding is generally a bad idea. http://blog.gdssecurity.com/labs/2010/2/12/abusing-wcf-to-perform-remote-port-scans.html Know the risks...
