Client authentication dialog is not implemented (always blank)

FX runtime build : (#282) http://jfx.sfbay.sun.com/hudson/job/presidio-deploy-scrum/label=windows-i586-14/lastSuccessfulBuild/artifact/artifacts/bundles/release/javafx-2.0-beta-windows-i586.exe
and promoted b41

JDK build : jdk7-b147

Os: winxp/win7
Browser: IE8/IE9/IE7

Client authentication does not work with fx at all. It has been noticed that "Request Authentication" dialog does not contain any certificate entries related to browser/deployment keystore and as a result applet fails to load at all (spinning image keeps on running inside the applet area))

Steps to reproduce:
----------------------------
1) Install jre and fx runtime
2) Import following cert into browser(IE) personal and deployment clientAuth keystore
http://sqeweb.us.oracle.com/deployment2/jitu/plug-bug/jitu.p12
password: changeit
3) Now try to load following applet inside the IE browser
https://mossad.us.oracle.com:8443/clientAuth/tests/fxfeaturesTest/fxfeaturesTest/html/GetParamsUnNamedInit.html
4) Accept the security pop-up
5) Inside Java Based "Authentication required" pop-up enter password as "changeit"
6) if you can notice that "Request Authentication" dialog is empty with not certificate/signer CA listed inside it then bug is reproduced
