Sairam,
Funny, I ran into the same issue. We temporarily used the AAA Policy, which isn't ideal, since it still looks for a username (pulled from BA headers in our case).
I started working on an XSLT transformation script:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"

I haven't fully tested it yet, but it should give you a start. You have to create stylesheet parameters for $username and $key. Please let me know if you change anything in order to get it to work.
Thanks,
