My .02 worth,

I would think that the configuration change would be on the Tomcat side, not 
the ISAPI Connector side as a new version of the Connector wasn't released, so 
everything would stay the same on the IIS side. Only the info in the server.xml 
would change, i.e. RequiredSecret to Secret, etc.
