 In a multisite environment ALLOW_UNFILTERED_UPLOADS does not work. It only
 works for super admin. /wp-includes/capabilities.php line ~385.
         case 'unfiltered_upload':
                 if ( defined('ALLOW_UNFILTERED_UPLOADS') &&
 ALLOW_UNFILTERED_UPLOADS && ( !is_multisite() || is_super_admin( $user_id
 ) )  )
                         $caps[] = $cap;
                         $caps[] = 'do_not_allow';


 I have a site where the client needs to be able to upload files that are
 created by various CAD applications, too numerous to name them all, I
 don't even know them all. The mime type varies on these file depending on
 what application is creating them, there seems to be no standardization
 for extension/mime type in CAD applications and each file extension is
 only allowed a single mime type. Due to this I must constantly fiddle with
 the allowed files and mime types so that they can upload them. This is
 ridonkulous as there seems to be no other way on multisite to allow
 unfiltered uploads.
