IIsProxy version for windows authentication

We are in the process of installing windows authentication to our EP 6.0 portal. We are running on SP 11 J2EE with portal SP 11 patch 3.

The first question I have in document “Using Header variables or Integrated Windows Authentication” section “Installing the IIsProxy module” says for security reasons we need to install version 1.7.0.0. Was this version released, we cannot find it on the service market place?

My second question, when we use version IISPROXY16_2-10001433.SAR the authentication mechanism works fine to the portal but I cannot navigate within the portal, it looks like the screen get stuck on the first Iview no matter what role you choose. When we use version IISPROXY15_0-10001969.SAR things work fine. I increased the trace while using IISProxy 16.2 but there were no errors in the logs. We would like to be on the latest version. Any idea what might be the problem?

Thanks for your help,
