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
