A Joomla-MediaWiki authentication bridge.

This project consists of two parts:

• MediaWiki Login: A Joomla plugin (JED) which sets a cookie in the users web browser.
• AuthJoomla2023: A MediaWiki extension which reads the cookie and automatically logs the user in.

A valid Joomla session allows access to the wiki, without having to log in into the wiki. A wiki user profile is automatically created for the user on the first visit.

This project is a successor of AuthJoomla2 by Harold Prins.
It's a complete rewrite done by Christian d'Heureuse in 2023.

The configuration parameters are mostly the same as for AuthJoomla2.

To install the Joomla plugin, create a ZIP file from the two files in the joomla directory. Or use the ZIP file mediawikilogin-x.y.z.zip from the releases page. Upload and install this zip file as a Joomla extension.

Configure the following parameters in the Joomla admin backend under "Extensions" / "Plugins".

• Secret Word for cookie crypto check: (choose your own secret word)
• MediaWiki cookie subdomain: empty if your Wiki uses the same domain (host) name as your Joomla, otherwise the name of the Wiki subdomain

Copy the files from the mediawiki directory to wikifiles/extensions/AuthJoomla2023. Or use the content of the ZIP file AuthJoomla2023-x.y.z.zip from the releases page.

Set the following parameters in LocalSettings.php:

$wgGroupPermissions['*']['read'] = false;
$wgGroupPermissions['*']['edit'] = false;
$wgGroupPermissions['*']['createaccount'] = false;
$wgGroupPermissions['*']['autocreateaccount'] = true;

$wgAuthJoomla_security_key   = '(secret word)';     // same as in Joomla
$wgAuthJoomla_TablePrefix    = 'jos_';              // Joomla table name prefix

$wgAuthJoomla_MySQL_Host     = 'localhost';         // Joomla MySQL host name
$wgAuthJoomla_MySQL_Username = 'db-user';           // Joomla MySQL user name
$wgAuthJoomla_MySQL_Password = 'db-password';       // Joomla MySQL Password
$wgAuthJoomla_MySQL_Database = 'db-name';           // Joomla MySQL database name

wfLoadExtension('AuthJoomla2023');

Edit the special Wiki page MediaWiki:Loginreqpagetext and add a link to your Joomla login page.
