The PluggableAuth extension provides a framework for creating authentication and authorization extensions. PluggableAuth provides the shared code necessary to implement these extensions. PluggableAuth is especially useful for use with enterprise authentication servers accessed through layered mechanisms such as OpenID Connect or SimpleSAMLphp. Authentication extensions subclass the abstract
PluggableAuth class. Because wiki sysops may wish to limit access to a subset of all authenticated users, PluggableAuth provides an authorization hook, PluggableAuthUserAuthorization. In addition, in order to augment MediaWiki's group information with that from an external provider, PluggableAuth provides the PluggableAuthPopulateGroups hook.
- Download and place the file(s) in a directory called
- Add the following code at the bottom of your LocalSettings.php:
wfLoadExtension( 'PluggableAuth' );
- The createaccount or autocreateaccount user rights must be granted to all users. See User rights.
- Configure as required
- Done - Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
|$wgPluggableAuth_EnableAutoLogin||false||Should login occur automatically when a user visits the wiki?|
|$wgPluggableAuth_EnableLocalLogin||false||Should user also be presented with username/password fields on the login page to allow local password-based login to the wiki?|
|$wgPluggableAuth_EnableLocalProperties||false||If true, users can edit their email address and real name on the wiki. If false, the default, they cannot do so. Note that, if you rely on email address and/or real name returned from the authentication provider in any way, you should leave this setting at its default value.

To change the text on the Log in button on the
Special:Userlogin form from the text "Log In With PluggableAuth", you can edit the page
The class specified by
$PluggableAuth_Class must implement the following functions:
public function authenticate( &$id, &$username, &$realname, &$email, &$errorMessage )
- Called to authenticate the user.
- The parameters are used to return the user id, username, real name, and email address of the authenticated user and, if the user cannot be authenticated, an optional error message.
$idis an integer and the remaining parameters are all strings. If the user cannot be authenticated and no value is set for
$errorMessage, a default error message is displayed.
$idmust be set to
nullif the user is new, in which case
PluggableAuthwill add the user to the database.
- Must return true if the user has been authenticated and false otherwise.
- If the return to URL, the name of the page, or the query parameters from the page that login was initiated from are necessary in the authenticate() function, they may be accessed as follows:
use \MediaWiki\Auth\AuthManager; ... $authManager = AuthManager::singleton(); $returnToUrl = $authManager->getAuthenticationSessionData( PluggableAuthLogin::RETURNTOURL_SESSION_KEY ); $returnToPage = $authManager->getAuthenticationSessionData( PluggableAuthLogin::RETURNTOPAGE_SESSION_KEY ); $returnToQuery = $authManager->getAuthenticationSessionData( PluggableAuthLogin::RETURNTOQUERY_SESSION_KEY );
public function saveExtraAttributes( $id )
- Called after a new user has been authenticated and added to the database to add any additional information to the database required by the authentication mechanism.
public function deauthenticate( User &$user )
- Called when the user logs out to notify the identity provider, if necessary, that cleanup such as removing the user's session should be done.
Authorization hooks use the PluggableAuthUserAuthorization hook to register an implementation of the following function:
function authorize( User $user, &$authorized )
$useris the User object for the user requesting authorization
$authorizedmust be set to true if the user is authorized and false otherwise.
- Return true to call other authorization hook implementations and false to skip them.
