Thanks to this list I know have my wiki integrated into the local network.
It all works except that it does not pull the email from AD.
This:
$wgLDAPPreferences = array('HPM' => array( 'email' => 'mail','realname' => 'displayname'));
pulls the realname and populates the correct field, but the email field remains stubbornly empty.
Is there another setting somewhere I need to enable and/or disable?\
