Thread:Extension talk:Lockdown/Lockdown does not seem to work for users not logged in

I setup a namespace define("NS_project", 1006); define("NS_project_TALK", 1007);

$wgExtraNamespaces[NS_project] = "project"; $wgExtraNamespaces[NS_project_TALK] = "project_talk";  // underscore required

require_once "$IP/extensions/Lockdown/Lockdown.php"; $wgNamespacePermissionLockdown[NS_project]['*'] = array('sysop'); $wgNamespacePermissionLockdown[NS_project_TALK]['*'] = array('sysop'); $wgNonincludableNamespaces[] = NS_project; $wgNonincludableNamespaces[] = NS_project_talk;

I can read pages in this namespace if I'm not logged in. Can I prevent this?
