The problem is that, after successful external SSO, the browser is redirected to the originally requested mediawiki url but halts with a dialog stating "Internet Explorer can not download http://intranetsite.com:12843/index.php?title=Main_Page from intranetsite.com. .."
The php error log states " PHP Fatal error: Class 'Auth_remoteuser' not found in C:\wiki\Mediawiki\mediawiki- 1.6.3\LocalSettings.php on line 141"
The first thing I'd check is the browser cache. If a previous load of the main page failed when you were trying it out, it's possible that this latest request returned a '304 not modified' response and the browser showed the old cached error message.
