Extension:AccessControl/gu
If you need per-page or partial page access restrictions, you are advised to install an appropriate content management package. MediaWiki was not written to provide per-page access restrictions, and almost all hacks or patches promising to add them will likely have flaws somewhere, which could lead to exposure of confidential data. We are not responsible for anything being leaked.

The AccessControl extension allows restricting access to specific pages based on internal groups or group lists from user space.
MediaWiki in its default state is not designed as a Content Management System (CMS), but when used as a corporate or school intranet it is required to protect sensitive data. AccessControl has been developed for this purpose.
How this extension meets the requirements for site security
- Atom/RSS feeds, diff, & revision links : Page content is protected, but when opening a page from history a piece of raw content will appear. If the <accesscontrol> tag was placed at the beginning, a potential attacker may be able to see the names of contributing users!
- Listings & search : Unless otherwise noted, if there is any page with protected content in search results, the user is redirected away. Since extension version 2.5, searching may be allowed too. But it should be borne in mind that the displayed search results can compromise sensitive data. Therefore, do not write in your wiki sensitive information, such as passwords, that could be obtained through a fulltext search if searching through the contents of pages protected through an access control is allowed!
- Inclusion/transclusion, related rights, & other extensions: Pages containing the <accesscontrol> tag, or including another page protected by the <accesscontrol> tag, are secure. The <accesscontrol> tag is processed in raw wikitext before HTML conversion.
- Redirects: The problem with redirection was repaired in version 1.1
- API & action links: For each anonymous user the action class is automatically set to
false
, besides the view attribute for unprotected pages. Allowed actions for authorized users depend on the permissions settings of MediaWiki and the username listed in the access list pages use. - Edit Section & watching pages: Options are available only to registered users if they are logged in and are on the security access list.
- Files & images
- XML export (Special:Export)
- Warning: AccessControl version < 2.0, was based on a hook unprotected from MediaWiki's side before exporting pages to raw code. Therefore, if you use AccessControl version < 2.0, you must prohibit the special page to prohibit exporting the pages from MediaWiki.
- Author backdoor
- Extension AccessControl does not have a backdoor!
- Caching
- I recommend turning off caching. See the previous paragraphs.
More info about potential problems regarding security is on the page Security issues with authorization extensions .

Documentation
Manual (in Czech language for now) here as wiki page, but is prepared for translation. If you want to contribute to creating an English version, you must donate any amount of money to pay for a commercial translator, because the author does not have the time and skills for it. The man page (for now only Czech version) is part of the source code, and can be imported into your private MediaWiki instance if you want.
Installation
Step 1: Local Settings File
- First check that you have set these variables in the LocalSettings.php file. If not, set them:
$wgGroupPermissions['*']['read'] = true;
$wgGroupPermissions['*']['createaccount'] = false;
$wgGroupPermissions['*']['edit'] = false;
$wgGroupPermissions['*']['writeapi'] = false;
$wgGroupPermissions['*']['createpage'] = false;
$wgGroupPermissions['*']['createtalk'] = false;
- Add the following lines to the bottom of your LocalSettings.php:
wfLoadExtension( 'AccessControl' );
Step 2: Read manual
Version 6.0 supports the old syntax of this extension. New syntax based on template parameters is very sophisticated. But for base use we can still use AccessList created by the old syntax, and protect pages by element accesscontrol.
Using
The new version has a new access rights setting system, based on template parameterization. If the parser encounters any of the following parameters while processing a template, it will call AccessControl to check if the user has access to the content.
- isProtectedBy - સભ્ય સમૂહોની યાદી
- readOnlyAllowedGroups - User groups with read-only access
- editAllowedGroups - User groups with edit access
- readOnlyAllowedUsers - List of users who can only read the content of the site
- editAllowedUsers - A list of users with editing rights
- readOnlyAllowedUsers - List of users who can only read the content of the site
- editAllowedGroups - User groups with edit access
- readOnlyAllowedGroups - User groups with read-only access
Within a single template, all of the above parameters can be used at the same time, so the indentation indicates their hierarchical position in terms of rights. You will learn more in the description of each parameter, where examples will also be given.
editAllowedUsers
Using this parameter turns a regular template into a list of users.
Each user whose name is specified in this parameter will have the right to edit the page into which the template with this parameter will be inserted.
And also all pages that use it in the isProtectedBy
parameter.
If more than one user is specified, their usernames are separated by a comma.
Simple example self-protected page (i.e. 'MyPage'
) where is in code used 'Template:Warning'
:
{{Warning
| 1 = This page is protected
| editAllowedUsers = John Doe, Jane Doe
}}
I can be used to protection another page, if the WikiText content use any template with the parameter 'isProtectedBy'
, where is as value name the self-protected page 'MyPage'
.
ઉદાહરણ જુઓઃ
…
| isProtectedBy = MyPage
…
It can be (not must!) edited by Page Form.
'edit'
action is only allowed for verified users. Extensions ConfirmAccount and ConfirmEdit (CAPTCHA) recommend.Using of the old syntax
First create User Groups. It may be any page stored in the main namespace, only colon must be after first word in the name. User lists can be a page in the namespace titled "Department" Each username appears as a list item.
* John Doe
* Jane Doe (ro)
- User names listed with "(ro)" at the end can only read the protected article, not edit it. For other groups of users, you can create another member list with the name Department in another namespace. Note that the user's name must start with a capital letter!
- Example tag code
<accesscontrol>Administrators,IT:Department,Sales(ro)</accesscontrol>
Configuration
- Check the settings in
extension.json
file.
These can be set in LocalSettings.php:
$wgAdminCanReadAll = true; // Administrators can read all restricted pages
- Depending on localization, your wiki needs pages created to which anonymous or unauthorized users will be redirected. You have to create them in advance because some of them can't access pages from another page.
- The safety of the page is provided by the <accesscontrol> tag. If there isn't a tag or the page is empty, it's freely accessible to logged-in users that can read and edit the page. No user, logged in or anonymous, will have read-only access.
- Members from groups listed in the <accesscontrol> tag can edit the page only if the group title isn't listed with "(ro)" and if they don't have read only access set in the group member list.
- By default the variable
$wgAdminCanReadAll
is set totrue
so that members of the sysop group can edit user group pages in any namespace.
Attention
For version < 4.1
MediaWiki versions: | 1.29 – 1.36 |
If for some reason you cannot upgrade your MediaWiki to version 1.39 LTS, you can continue to use version 4.1 of the form-support branch. If you have a problem with the update, because any problem occurred and blocked your actualization, write in the discussion. MediaWiki is very complexity software, and sometime a little bug may be as big problem for admins without the programming experiences.
form-support
was developed for using with the Extension:Page Forms – as accesslist you may use any template, but the old syntax of accesslists is supported.
Changes for using with the VisualEditor was implemented too.
You may get code from git:
git clone -b form-support https://gerrit.wikimedia.org/r/p/mediawiki/extensions/AccessControl.git
If your MediaWiki Version (≥ 2.6) isn't recommend for use, because have not support of the maintainer.
MediaWiki versions: | 1.21 – 1.28 |
Version 2.5.1 is strongly recommended to be used.
For version < 2.3
- There was a problem in function fromTemplate() causing AccessControl to ignore tags from included pages or templates. Actualization is recommended!
For version ≥ 2.0
MediaWiki versions: | 1.18 – 1.20 |
- Pages can have only one <accesscontrol> element.
- If the user is a member of multiple groups, the group that gives them more access is assumed.
- This extension uses a MediaWiki hook that is called whenever a search result is displayed. This means that a page that has an ACL will trigger an "Access Denied" message for end users who happen to search for text contained in a protected page. A simple solution is to put pages that require AccessControl into another namespace and then disable searching for that namespace. Although this isn't really a bug, it is undesirable behavior. Click here for an example showing a work around.
For version ≤ 1.3
MediaWiki version: | ≤ 1.17 |
- Groups from MediaWiki must not be in localized form!
sysop
cannot beSprávce
, etc. - A page may have multiple <accesscontrol> elements, with access accepted from groups in any tag.
- Anonymous users do not have access to pages protected by <accesscontrol> elements.
- If variable
$wgAdminCanReadAll
istrue
, sysops always have edit access.

Notes
- ↑
Unlike Group Based Access Control , double commas aren't used to split the content of an
<accesscontrol>
tag when more access lists are used. Only one comma is required. And is not necessary to use the,,
separator at the end of the element content.
