AuthAzureEasyAuth

This MediaWiki extension allows you to leverage Authentication / Authorization of Azure App Service. It is meant to run in App Service's environment and it won't likely run on your custom server.

Installation

Installation of this plugin consists of two parts - enabling Authentication/Authorization in Azure App Service and then enabling this extension within MediaWiki itself.

Configure Azure App Service

First, App Service Authentication/Authorization has to be enabled in Azure App Service. You can do that by following the tutorial in official docs.

Multitenant environment

If you would like to use this extension from within a multitenant environment - for example from multiple Azure Active Directory tenants, you have to do following steps:

• Mark the application in Azure AD as multitenant
• Add additional issuers to the $wgAuthAzureEasyAuthIssuers array.

Configure MediaWiki

Next you need to configure your MediaWiki instance. You have to put following to your LocalSettings.php:

####################################################
# Extension: AuthAzureEasyAuth
wfLoadExtension( 'AuthAzureEasyAuth' );
# List of valid issuers, in basic scenarios, this will contain only one entry.
$wgAuthAzureEasyAuthIssuers = [
    "https://sts.windows.net/{tenant-id}/",
];

# Make this wiki private and disable account creation to anonymous users.
$wgGroupPermissions['*']['createaccount'] = false;
$wgGroupPermissions['*']['read'] = false;
$wgGroupPermissions['*']['edit'] = false;
# Since manual user creation is disallowed, we should allow this extension to create users. If you don't want this extension to create users, set the option below to `false`
$wgGroupPermissions['*']['autocreateaccount'] = true;
# By default, MediaWiki has `@` as invalid character in username, we have to override it so e-mail addresses work as usernames.
$wgInvalidUsernameCharacters = '';
# Additionally, as per documentation `https://www.mediawiki.org/wiki/Manual:$wgInvalidUsernameCharacters` we should also override the delimiter for UserRights page.
$wgUserrightsInterwikiDelimiter = '<@>';
####################################################

Obtaining issuer URL

For Azure AD, this is very simple - it can be done either from Azure Portal by copying the Directory ID and replacing {tenant-id} in the $wgAuthAzureEasyAuthIssuers array. It can also obtained by visiting https://login.microsoftonline.com/{your-domain}/.well-known/openid-configuration and copying issuer value from the JSON.
