Webserver Auth Module

Nobody responded to this, and there's nothing in the issue queue suggesting someone is working on it.

Is this something anyone is interested in? I'd love to get this functionality into Drupal 5.x for an intranet I'm working on for my employer.

I started from // $Id: webserver_auth.module,v 1.13.2.3 2006/03/03 05:08:12 weitzman Exp $ and trimmed some stuff out. It works for us by forcing the login if there is an account for that person. I removed the register feature because we don't use it, but this might get you started on re-implementing that feature. I apologize if its sloppy or not the "right" way to do things.

function webserver_auth_init() {
  global $user, $account;

  if ($user->uid) {
    //do nothing because user is already logged into Drupal
  }
  else {
    if ($name = $_SERVER["REMOTE_USER"]) {
      // user is logged into webserver.
      $account->name = $name;
      //modules get to change the user bits before saving. use a global $account to do so.
      // only loaded modules will see this hook
      module_invoke_all("webserver_auth");
      // if we are in bootstrap, load user.module ourselves
      if (!module_exists('user')) {
       drupal_load('module', 'user');
      }

      // try to log into Drupal. if unsuccessful, use anonymous
      if ($user = user_load($array = $account)) {
      	watchdog("user", "Session opened for $user->name.", WATCHDOG_NOTICE);
      }
      else {
      	$user = drupal_anonymous_user();
      	watchdog("user", "Session opened for Anonymous.", WATCHDOG_NOTICE);
      }
    }
    else {
      // do nothing. user isn't logged into web server
    }
  }
}

Anyone willing to update for 5.x or give instructions on how to install this to 5.x and modify it to work? Thank you for your work in advance.
