Problems with MediaWiki's AccessControl extension - mediawiki

Question

I've installed the AccessControl MediaWiki extension however it seems like it causes an access denied error if you search for anything even contained within the page that is access controlled.
Anyone using this extension?
All I want to do is hide one page in the wiki from everyone except for 5 people.
MediaWiki version 1.18.0
AccessControl version 2.1

Answer 1

I solved it by adding another namespace to put the pages I need to secure in. I then removed the namespace from being searchable by implementing the searchablenamespaces hook.
By doing this, there will never be an access denied page displayed just by searching for text that happens to be in an access controlled page.
Here is the code for $IP/extensions/NoSearchNameSpace/NoSearchNameSpace.php
<?php
// This is a quick hack to remove certain listed namespaces from being searchable
// Just set a list of namespace IDs in the wgNoSearchNamespaces array in LocalSettings
// ie $wgNoSearchNamespaces = array(500,501) would remove 500 and 501 from being searched
$wgHooks['SearchableNamespaces'][] = 'noSearchNameSpace';
function noSearchNameSpace($arr){
global $wgNoSearchNamespaces;
foreach($wgNoSearchNamespaces as $ns){
unset($arr[$ns]);
}
return $arr;
}
Example LocalSettings.php entry:
// Add two custom namespaces. One for ACL pages.
// one for pages that will be ACL'd that should not be searched.
$wgExtraNamespaces[500] = "ACL";
$wgExtraNamespaces[501] = "NoSearch";
// Include the NoSearchNamespace extension
require_once("extensions/NoSearchNamespace/NoSearchNameSpace.php");
$wgNoSearchNamespaces = array('500','501');

Answer 2

I tried it with 1.20.2, and had the problem when a page I was searching for contained text being searched, putting it in the list of search results, which provoked an error because the "hookUserCan" function in AccessControl.php didn't return a value. To try to fix this, I modified line 341 of AccessControl.php ("return doRedirect( 'accesscontrol-info-anonymous' );" to "return false;". This forces the search results to return just the title of the page, and then gets a permission error if an unauthorized user tries to open it. This is not a perfect fix, but it is sufficient for my purposes.
Editted, this is a better answer:
I made some modifications to the AccessControl.php program, and now it appears to work ok with MediaWiki user groups. A remaining problem is that the TITLES of protected pages show in the search results. This is fixable in the main MediaWiki source code (SpecialSearch.php, around line 562), but according to comments in that code, it would screw up the paging.
Here is my git directory, which can be unzipped to $IP/extensions/AccessControl:

Here is just the AccessControl.php file: http://pastebin.com/WnyB6gBw
Note that this has only been tested (briefly) with MediaWiki 1.20.2. I'm hoping that the author of the extension will review what I did and fix whatever problems remain.

I fixed this error by adding
return false;
after ALL LINES that say
doRedirect( 'accesscontrol-info-anonymous' );
