OBIEE 11g - Integrating via external corporate website to OBIEE

Question

Hi all -
Unusual challenge, our we offer a hosted application (SaaS) where our users are authenticated on our application. Recently, we've invested in OBIEE 11g and have successfully deployed recommended Oracle Enterprise Deployment. We have a custom security solution (user permissions in Oracle tables, not LDAP), and have not implemented Oracle Identity Mgmt and don't plan to.
We would like to use GoURL / Action Framework to access Report content, dashboard content, content as port lets embedded in an app dashboard to an iFrame.
My Question: can we configure OBIEE to accept just "username" without password in a trusted login scenario? we are trying not to expose password in URL (encrypted or clear text).
We done an exhaustive search to review GoUrl, web service / soap calls, reviewing impersonator passcode techniques (everyone having same pad in initialization block), etc.
Thank you in advance for your most needed responses,

There is a good post that lead me on the way to solving this problem here:

The code he posts won't work for 11g, but it's close.
Paste this code into a text box on each page of your dashboard, make sure you check the box that says "contains HTML"
<script type="text/javascript">
var tds = document.getElementsByTagName('table');
for (var td = 0; td < tds.length; td++) {
if (tds[td].className != 'HeaderTopBar' && tds[td].className != 'HeaderSecondBar' ) {
continue;
if (tds[td].className == 'HeaderTopBar') {
//alert (tds[td].className);
var x = tds[td].parentNode;
//alert (x.className);
x.removeChild(tds[td]);}
if (tds[td].className == 'HeaderSecondBar') {
//alert (tds[td].className);
var x = tds[td].parentNode;
//alert (x.className);
x.removeChild(tds[td]);}
</script>
