Extension:AccessControl/ja

内部グループまたは利用者スペースのグループ リストに基づいて、特定のページへのアクセスを制限できるようにする

MediaWikiは既定の状態ではコンテンツ管理システム (CMS) として設計されていませんが、企業や学校のイントラネットとして使用する場合、機密データを保護する必要があります. AccessControl は、この目的のために開発されました.

この拡張機能がサイト セキュリティの要件をどのように満たしているか

 * 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 &lt;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 &lt;accesscontrol> tag, or including another page protected by the &lt;accesscontrol> tag, are secure. The &lt;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.


 * ファイルと画像


 * 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.

説明文書
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.

Step 1: Local Settings File

 * Add the following lines to the bottom of your LocalSettings.php:

If you're not sure which namespace ID to use, then use 730 and 731 as detailed at the extension defalt namespaces listing. See step 2 for more information on how to do this.
 * Add a namespace to the LocalSettings.php file for the purpose of creating groups.
 * 詳細情報は を参照してください.
 * Check the settings in AccessControl.php. These can be set in LocalSettings.php:

Step 2: Create User Groups

 * This method has changes in the latest version, please see note 1 at the bottom of this page. (User lists must be stored in the main namespace).

User groups are simply standard wiki pages that are part of a namespace other than the default namespace. For ease of use, it is suggested that a specific custom namespace is created for the explicit purpose of managing access control list pages For your custom namespace, if you're not sure which namespace ID to use, then use 730 and 731 as detailed at the extension defalt namespaces listing. For your convenience, IDs 730-739 are reserved for your use for this extension.

Furthermore IT: should not be specified in the accesscontrol tag, just "Department"
 * Create a wiki page with a users list in any namespace
 * It is not sufficient to simply create a page with a colon in the name, this extension requires the use of a namespace and one or more pages within namespaces
 * Page Name Example: My:Group
 * The namespace is My
 * The group page is Group
 * This is the name of user group
 * Users are added to the group in a bulleted list
 * Page Content Example
 * Presume that the namespace IT exists
 * Note that in v3.0 you also need to register the namespace IT either in LocalSettings.php e.g.  or modify the.
 * Create a page in the namespace titled "Department"
 * Create users "John Doe" and "Jane Doe" in the group. The group information is contained on the page "Department".
 * Each username appears as a list item.


 * 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!


 * Tips: To protect the IT namespace you can use the Lockdown extension, but you can also use the &lt;accesscontrol> tag to protect it.

Step 3: Additional Access Control

 * 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 &lt;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 &lt;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  is set to true so that members of sysop can edit user group pages in any namespace.


 * Example tag code

In this example, all users from the groups "Administrators", "IT:Department" and "Sales" can read the page but only the users from "Administrators" group (if exists) and John Doe from "IT:Department" user group can edit it.

Usage on Pages to Control Access
That is for the installation. To restrict access to a page for specific user groups, just include the names of the allowed user groups (separated by commas) as the content of the &lt;accesscontrol> tag in the top of the content page.

注意
Version 2.5.1 is strongly recommended to be used.

バージョン 2.3 未満

 * There was a problem in function fromTemplate causing AccessControl to ignore tags from included pages or templates. Actualization is recommended!

バージョン 2.0 以降

 * Pages can have only one &lt;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.

バージョン 1.3 以下

 * Groups from MediaWiki must not be in localized form! sysop cannot be Správce, etc.
 * A page may have multiple &lt;accesscontrol> elements, with access accepted from groups in any tag.
 * Anonymous users do not have access to pages protected by &lt;accesscontrol> elements.
 * If variable  is true, sysops always have edit access.

MediaWiki Version Testing

 * Version 4.0 is obsolete (T281848). Upgrade recommend.
 * バージョン 3.0.1 は MediaWiki 1.34.0 でテストされましたが、廃止されました. アップグレードをお勧めします.
 * バージョン 2.5.1 は MediaWiki 1.33.0-alpha (5eb97ec) でテストされました
 * バージョン 2.6 は MediaWiki 1.27.0-rc.0 (57f722a) でテストされました
 * バージョン 2.5 は MediaWiki 1.27.0 (git リポジトリから) でテストされました

History
The first version of this extension (1.x) was based on Group Based Access Control, but without bugs the original had.
