Thread:Project:Support desk/Unable to get past http 500.0 error - no details provided (even on server)

Win2k8 - IIS7

NTLM Auth extension with Honza's SpecialUserLogin.php fix - Extension_talk:Windows_NTLM_LDAP_Auto_Auth

MediaWiki 1.16.2

PHP 5.2.17 (isapi)

MySQL 5.5.9

I am getting a 500 response, and have run out of ideas for troubleshooting. The problem only shows up when I enable my config for LDAP authentication, but my ldap_debug.log file show authentication completing successfully

$wgShowExceptionDetails = true; is set in LocalSettings.php
