Security Concerns?
Can anyone comment on the security risks associated with this extension? The warning at the top of the page is rather dire, and my clients have asked for this functionality, but I am hesitant to do so until I understand the nature of the risk. Is it simply that access controls can not be "guaranteed" to work, so don't stake your career on "private" articles not being seen by all users? Or can someone gain shell on my mother's toaster, hax0r *pedia and impregnate my goldfish? Seriously though, what are the risks?

Thanks! Thomsonj 22:57, 11 December 2008 (UTC)


 * The security risk connected with this extension is following:
 * is it possible or is it not possible to break into the shell? - the mediawiki is responsible for it, this extension doesn't have any influence to it. From this point of view the extension is secure.
 * In the today appearence the extension could be get round through redirection. If anybody makes a page with redirection to the secured private article, at that time it can be entered by anybody, no matter how the configuration of the rights is put on! That's why this extension is good to make together with others extensions. This is the most serious fault that I would like in the future to get rid of.
 * NOTICE - Security bug with accessibility on protected page over #REDIRECT was fixed in AccessControl extension v. 1.1
 * Want 16:41, 23 July 2009 (UTC)
 * Also, it's necessary to secure not only the articles but also the lists (so as nobody unauthorized could fill in himself)

Bug when using API
I try to write a bot that works on our local wiki.

But accessing a page via the API generates an error:

The URL is http:// /api.php?action=query&prop=revisions&titles=BrandMaker&rvprop=content|comment|user&rvdir=older&rvlimit=1&format=xml

Does anybody have a fix for that? --Fez 22:49, 23 January 2009 (UTC)

Need help in MediaWiki 1.14.0
Does this work under MediaWiki version 1.14.0? I can't get it to work. Here's what I did:

$wgExtraNamespaces[100] = "Access"; require_once("extensions/AccessControl.php");
 * I added the following to the end of the LocalSettings.php file:

*Test6 Page is being viewed! Access:Group
 * Created a user account with name "Test"
 * Created a page "..mediawiki/index.php/Access:Group", edited the page with the following:
 * Created a page edited with the following:

The problem is that any user can view this page, although the text "This page is protected!" appears. Oddly, if I write: Administrators,Access:Group The administrator can view the page, but the user "Test" can't, and goes to a "Wiki:No Access" page.

Any help is much appreciated! Thanks.


 * I'm having the same exact problem. I don't think the thing works in 1.14.

Seems like one more as Administrator or the comma has to be declared. Little bug?! thx alex ADD: Just tested:    with comma; ,  restrict access. not else. 3h research......

Cannot use MediaWiki::API when Access Control is installed
I'm playing with this extension and it's working well but I can no longer access my site using the Perl module MediaWiki::API when the extension is installed. Perl module uses the MediaWiki API (api.php) to access the Wiki. Have you run across this issue yourself? I should add that simply adding the line "require_once('extensions/AccessControl.php')" to LocalSettings prevents the module or script from accessing the Wiki, I haven't even created groups or access control lists yet. Thanks again.

Cannot use Access Control in a template call
This extension works well for me when I use strings like this in a plain page:

Access:Group1

However, if I try to call a template from a page, like:

Access:

it does not work. Your thoughts on this? Thanks again.

MediaWiki 1.15.1 Extension AccessControl DOES NOT WORK
We have done every step as desribed in this article HAve created custom namespace PC created page PC:Team included there a *User protected page with Administrators, PC:Team

And what we see? - User doesnt have access to protected page AT ALL!!!!!!!!


 * I'm having the same problem. Doesn't work with MediaWiki 1.15.1


 * Have new installed 1.15.1 Wiki, but protection does now work. Protected pages are free available.


 * you bungled the acesscontrol tag, you need to commas after Administrators and not one. Now, you need to comment out include clauses for accesscontrol extension in your LocalSettings.php file and edit the page and fix your accesscontrol tag. Enable accesscontrol extension by removing the comment.

Patches for AccessControl 1.1 in MediaWiki 1.15

 * can actually read group list from a namespaced page
 * correctly enable/disable edit tab
 * support both combinations of "edit" & "read" from page and group list.

 * support reading when page grants (ro) rights to a group
 * controlEditAccess(&$editpage): bugfix:
 * do extract groups before processing.
 * getUsersFromPages($skupina): align with documentation:
 * do interpret namespace prefix rather than using fixed namespace 0.

Disabling redirect on Search Pages including protected pages
in includes/specials/specialsearch.php find "goResult(" and replace by "showResult(" will avoid to be redirected automatically to your NO_ACCESS page when a restricted page you don't have access is included in results.


 * I tried the above code, but it leads to a page not found error. Looking at the code it appears that it should be "showResults(" not "showResult(".  However that just leads to a redirect as before.

Seems this is not solved yet... Has anybody found a solution/workaround yet? --217.91.154.83 15:14, 31 January 2011 (UTC)

Using mediawiki User Groups
While using this extension i noticed that mediawiki user groups were not called in the correct form. So if you want to give access to users in Administrators and Bureaucrats you have to put the following code on the page: sysop, bureaucrat (ro) and not as was stated on the extension pages, i.e. Administrators, ... , cheers, Carlos Sá

Error if group list is in a namespace (1.18.1)
Hi: I detected an error to retrieve user from a list in a page of other namespace distinct principal. In the line 125 of the current version, the extension retrieve the page from namespace 0, where the first argument is the namespace, but I've created a group list page in namespace 500, so the list is invalid and the extension doesn't work.

 * Click here for a solution for this problem.

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 ("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. --Ejcaputo (talk) 10:45, 2 January 2013 (UTC)


 * 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:


 * https://ejc.s3.amazonaws.com/AccessControlGit.zip


 * 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.

Search Problems
Hello,

I've got a problem with the search - function on my mediawiki. Since I have installed the extension "AccessControl", the search doesn't find the right results anymore. I created a couple of test pages, some of them with an accesscontrol - tag and some others without this tag. If I search for content that is in a few articles, I only get the message "MY:No Access ... There is currently no text in this page." Without this extension, I get a list with the results that I expected.

I hope someone can help me.


 * Notes section added. See here for solution regarding search.

Installation / usage problems MW 1.17
Hi, first of all: thanks for this extension! Looks promising. But I'm having problems with the installation / rights management, hope someone can help. Using MW 1.17 (that's where the problem might have started). 1st try: Downloaded v1.3 manually (AccessControl.php only), but the require_once command made the Wiki shut down completely. 2nd try: downloaded the AccessControl with git, got the 2.0 version, which might not be suitable? Anyway, didn't get any errors, so proceeded with that. Created namespaces according to Manual:Using_custom_namespaces, that worked, they are listed in http://installation_path/api.php?action=query&meta=siteinfo&siprop=namespaces. => Installation step 1 completed. Now step 2 causes trouble, and I'm not sure if I understand the instructions. Say my namespace's ID is 500, name is Foo, with constants defined by "define("NS_FOO", 500);". Then I created a new page called Foo:Foo (first Foo being the namespace, second Foo being the page name), and listed all user names there, like this: *User:User1. At this stage, I was already unsure of what exactly to use where (namespace name, ID or constant, how and where to list the users?). Then, I created a template for page protection with sysops,Foo:Foo , and used that on all pages I wanted to protect. Created a testuser account with normal user rights (not in any user group) - and can still access all "protected" pages with that testuser account. Can anyone help? Much appreciated, thanks! --Justanotherday (talk) 13:37, 17 July 2012 (UTC)
