contrib modules

I was wondering if anyone here has had any success using the Webserver Authentication module (http://drupal.org/project/webserver_auth)? I was able to get it working -- to a point. The problem is, when a person visits a site using the module and the login session is first established, Drupal returns an access denied error ("You are not authorized to access this page."). By refreshing the screen or navigating to another page, the error disappears and one is logged in just fine for the rest of that session.

I've added to Webserver Authentication's issue cue:

I'm this close to completing my company's new Drupal site, except when we moved it to the production server we started having issues with the Google Appliance module. I submitted an issue on the module's page, and am now waiting for the developer to help me. That being said -- as the days go by I'm increasingly uncomfortable with the level of dependence here. The site is ready to launch, people are waiting on it, and I have to wait until this developer decides to address my issue because the site is worthless without the search working.
