The OpenID Connect extension extends the PluggableAuth extension to provide authentication using OpenID Connect.

Special thanks to jumbojett for the OpenID Connect PHP library used by this extension.

Installation

Preconditions

This extension requires PluggableAuth to be installed first. If you are updating from version 4.x or below to version 6.x or above, you will need to update to version 5.x first.

Extension

  • Pobierz i umieść plik(i) w katalogu o nazwie OpenIDConnect w folderze extensions/.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/OpenIDConnect
  • Dodaj poniższy kod na dole twojego pliku LocalSettings.php : 
    wfLoadExtension( 'OpenIDConnect' );
  • Uruchom skrypt aktualizujący, który automatycznie stworzy potrzebne tabele dla tego rozszerzenia.
  • Install dependencies.
  • Configure as required.
  • Yes Zrobione – Przejdź do Special:Version na twojej wiki, aby sprawdzić czy rozszerzenie zostało pomyślnie zainstalowane.

Zależności

The OpenIDConnect extension requires the CURL PHP extension and the OpenID Connect PHP library. If you are following the standard installation procedure and downloaded the archive from mediawiki.org, the dependencies have been bundled and there is no further action required.

If you are following the development/contributor installation procedure using git, add the line "extensions/OpenIDConnect/composer.json" to the composer.local.json file in the root directory of your wiki, e.g. 

{
	"extra": {
		"merge-plugin": {
			"include": [
				"extensions/OpenIDConnect/composer.json"
			]
		}
	}
}

Then run composer update in the root directory of your wiki. This will install any dependencies (i.e. the jumbojett OpenID Connect PHP library).

Konfiguracja

Parameters

Most of the configuration for OpenID Connect is handled by a file found at /.well-known/openid-configuration[1] on the provider's domain.

This contains most of the settings that are needed to handle authentication.

Flag Default Description
$wgPluggableAuth_Config (see Extension:PluggableAuth#Configuration) [] A mandatory array of arrays specifying the OpenID Connect issuers and their configuration. The data field of the array contains an array that has the following keys:
providerURL Wymagane the URL of the issuer (e.g. https://accounts.google.com/ for Google, https://api.slack.com/ for Slack) that is used to find the "well-known" file mentioned above (e.g. https://accounts.google.com/.well-known/openid-configuration for Google)
clientID Wymagane
clientsecret Wymagane
proxy Optional URL
scope Optional string or array of strings to be passed to the issuer, defaults to [ 'openid', 'profile', 'email' ]
preferred_username Optional preferred username attribute name from issuer to use, indicating that there will be an attribute with this name provided by the issuer whose value will be the preferred username for the user; defaults to the string 'preferred_username'; set to empty string if you do not want to use a preferred username attribute
verifyHost Optional boolean to enable/disable host verification; default: true
verifyPeer Optional boolean to enable/disable SSL peer verification; default: true
authparam Optional associative array of authentication parameters to be passed to the issuer
providerConfig Optional associative array used to alter a provider's endpoints and other attributes
issuerValidator Optional boolean function that takes one string parameter, the issuer, and returns whether the issuer is valid (version 7.1.0+)
preferredUsernameProcessor Optional callable that takes two parameters (preferred username string and the array of attributes returned from the identity provider) and returns a possibly modified preferred username to use for a new user (version 7.2.0+)
realnameProcessor Optional callable that takes two parameters (real name string and the array of attributes returned from the identity provider) and returns a possibly modified real name to use for a new user (version 7.2.0+)
emailProcessor Optional callable that takes two parameters (email address string and the array of attributes returned from the identity provider) and returns a possibly modified email address to use for a new user (version 7.2.0+)
useRandomUsernames Optional boolean to indicate whether to generate a random unique identifier to use for the username of a new user if no preferred username is provided (rather than the default of using User followed by a unique integer) (version 8.0.0+)
$wgOpenIDConnect_UseRealNameAsUserName false If a new user is being created in the database and no preferred username was provided by the issuer or preferred_username was set to null or the empty string, a value of true for this flag indicates that the user's real name, if provided by the issuer, should be used as the new user's username. If set to true, and no preferred username was provided by the issuer "User" for the first and starting with the second user "User" followed by a number will be used, e.g., "User", "User1", "User2", etc. The same naming happens if this parameter is set to false.
$wgOpenIDConnect_UseEmailNameAsUserName false If a new user is being created in the database, and no preferred username was provided by the issuer or preferred_username was set to null or the empty string, and either no real name was provided by the issuer or $wgOpenIDConnect_UseRealNameAsUserName was undefined or set to false, a value of true for this flag indicates that the name portion of the user's email address, if provided by the issuer, should be used as the new user's username. This parameter cannot be set to true at the same time $wgOpenIDConnect_UseRealNameAsUserName is set to true. In this case this setting will be ignored.
$wgOpenIDConnect_MigrateUsersByUserName false If a user already exists in the database with the same user name as the authenticated user and has null values for subject and issuer, use this user, setting the subject and issuer in the database to those of the authenticated user. This is useful when the wiki previously used a different authentication mechanism. If neither this parameter nor $wgOpenIDConnect_MigrateUsersByEmail are set to true the settings for user creation will be used as described above.
$wgOpenIDConnect_MigrateUsersByEmail false If a user already exists in the database with the same email address as the authenticated user and has null values for subject and issuer, use this user, setting the subject and issuer in the database to those of the authenticated user. This is useful when the wiki previously used a different authentication mechanism. If neither this parameter nor $wgOpenIDConnect_MigrateUsersByUserName are set to true the settings for user creation will be used as described above.
$wgOpenIDConnect_ForceReauth false When the user logs out from the wiki, force reauthentication with the identity provider at next login even if they have not logged out from the identity provider.
$wgOpenIDConnect_SingleLogout false When the user logs out from the wiki, also log out from the identity provider. This is not supported by all identity providers (e.g. Google).
$wgOpenIDConnect_PreferredUsernameProcessor null Callable that takes two parameters (preferred username string and the array of attributes returned from the identity provider) and returns a possibly modified preferred username to use for a new user; this value is only used if no value is provided for preferredUsernameProcessor in the config data section (version 7.2.0+)
$wgOpenIDConnect_RealNameProcessor null Callable that takes two parameters (real name string and the array of attributes returned from the identity provider) and returns a possibly modified real name to use for a new user; this value is only used if no value is provided for realnameProcessor in the config data section (version 7.2.0+)
$wgOpenIDConnect_EmailProcessor null Callable that takes two parameters (email address string and the array of attributes returned from the identity provider) and returns a possibly modified email address to use for a new user; this value is only used if no value is provided for emailProcessor in the config data section (version 7.2.0+)
$wgOpenIDConnect_UseRandomUsernames false Boolean to indicate whether to generate a random unique identifier to use for the username of a new user if no preferred username is provided (rather than the default of using User followed by a unique integer) and no value is provided for useRandomUsernames in the config data section (version 8.0.0+)

When configuring the identity provider, it will ask for a redirect URL or callback URL. Use the full URL to the Special:PluggableAuthLogin page for that value.

Connecting to a single issuer

A simple example of the $wgPluggableAuth_Config configuration for a single issuer is as follows: 

$wgPluggableAuth_Config[] = [
    'plugin' => 'OpenIDConnect',
    'data' => [
        'providerURL' => 'https://id.mycompany_abc.com/connect/',
        'clientID' => '.....',
        'clientsecret' => '.....'
    ]
];

Connecting to a multiple issuers

An example of the $wgPluggableAuth_Config configuration for multiple issuers is as follows: 

$wgPluggableAuth_Config["My Company's Connect Server"] = [
    'plugin' => 'OpenIDConnect',
    'data' => [
        'providerURL' => 'https://id.mycompany_abc.com/connect/',
        'clientID' => '.....',
        'clientsecret' => '.....'
    ]
];
$wgPluggableAuth_Config["Partner Company's Connect Server"] = [
    'plugin' => 'OpenIDConnect',
    'data' => [
        'providerURL' => 'https://id.partnercompany_def.com/connect/',
        'clientID' => '.....',
        'clientsecret' => '.....'
    ]
];

As of version 7.0.0, group synchronization is possible using the capability provided by the PluggableAuth extension. For information on configurating group synchronization, see the PluggableAuth documentation.

Przykłady

Google

Issuer configuration

  1. Using the Google Developer Console create a project.
  2. Click on the project, click on the hamburger menu (three horizontal lines in the top left), and click on APIs & Services -> Credentials on the menu.
  3. Click the Create credentials -> OAuth client ID button and select Web application. Fill in the consent screen information and save.
  4. Provide the redirect URI in Authorized redirect URIs[2]:
    https://[URLofWiki]/wiki/Special:PluggableAuthLogin
  5. Click Create Client ID.
  6. Note the Client ID and Client Secret that are assigned.

Extension configuration

The Google issuer is now configured. Add the corresponding configuration to your LocalSettings.php file, filling in the clientID and clientsecret fields with the values assigned above. 

$wgPluggableAuth_Config[] = [
    'plugin' => 'OpenIDConnect',
    'data' => [
        'providerURL' => 'https://accounts.google.com',
        'clientID' => '.....',
        'clientsecret' => '.....',
    ]
];

You may also assign other values such as proxy and authparam.

Azure Active Directory

Azure Active Directory is now Microsoft Entra ID.

Microsoft Entra ID

Entra ID is the new name of the service formerly called "Azure Active Directory."

Issuer configuration

  1. In the Azure portal, go to 'Active Directory' and then 'App Registrations'
  2. Register a new Application
    1. Provide a Name
    2. Likely specify 'Accounts in this org directory only'
    3. Provide redirect URI:[2]
      https://[URLofWiki]/wiki/Special:PluggableAuthLogin
  3. In the new app, go to 'Certificates and secrets' and create a new Client secret

Extension configuration

Using the 'Application (client) ID', Directory (tenant) ID, and Secret from the application, populate your "LocalSettings.php" file: 

$wgPluggableAuth_Config[] = [
    'plugin' => 'OpenIDConnect',
    'data' => [
        'providerURL' => 'https://login.microsoftonline.com/[tenantID]/v2.0/',
        'clientID' => '[Application (Client) ID]',
        'clientsecret' => '[Secret from Certs and Secrets]'
    ]
];
$wgOpenIDConnect_UseRealNameAsUserName = true;
In the provider URL, you don't have to use the tenant ID if you don't remember it. Instead, you can use your onmicrosoft.com tenant subdomain. For instance, https://login.microsoftonline.com/mytenant.onmicrosoft.com/v2.0/.

Extension configuration with Group mapping

$wgPluggableAuth_Config[] = [
    'plugin' => 'OpenIDConnect',
    'data' => [
        from above example
    ],
	'groupsyncs' => [
		[
			'type' => 'mapped',
			'map' => [
				'sysop' => ['groups' => '8d1cc10c-3e95-4637-941d-0c1237352e85'],
				'interface-admin' => ['groups' => 'See where to find Object ID below'] 
			]
		]
	]
];
  1. In Azure, go to `Manage` -> `Token configuration`. Click `Add group claims`, select "Groups assigned to the application (recommended for large enterprise companies to avoid exceeding the limit on the number of groups a token can emit)".
  2. Find app in Enterprise applications, and go to `Manage` -> `Users and groups`. Add group.
  3. You can now click on the group and copy the `Object ID` and paste above.
  4. You need to relogin to take effect.

Keycloak

Keycloak main.

Issuer configuration

Assumptions:

  • Your Keycloak realm name is acme
  • Your Keycloak URL and Port is https://keycloak.local:8080
  • Your Keycloak Client ID is set to mediawiki
  • Your auto-generated client secret is 12345

Extension configuration

$wgPluggableAuth_Config[] = [
    'plugin' => 'OpenIDConnect',
    'data' => [
        'providerURL' => 'https://keycloak.local:8080/realms/acme',
        'clientID' => 'mediawiki',
        'clientsecret' => '12345'
    ]
];

Troubleshooting

  • If you're running into trouble, like "The provider {$param} could not be fetched. Make sure your provider has a well known configuration available.", your URI[3] is wrong. You can test the correctness by calling https://keycloak.local:8080/realms/acme/.well-known/openid-configuration in your browser. If you get back a long JSON, the path is correct.
    • Another way to verify the 'providerURL' is to check it against the ‘Redirect URI’ at Keycloak>Identity Providers>keycloak-oidc, i.e.: https://keycloak.local:8080/realms/acme/broker/keycloak-oidc/endpoint. For 'providerURL' you need the portion up to one level below realms.
  • Make sure the redirect uri provided by this OIDC[4] plugin is set valid for your keycloak-server under acme -> Clients -> mediawiki -> Settings -> valid redirect uris . For testing purposes you can add a wildcard "*".

Okta

Issuer configuration

Okta OIDC app settings 

Allowed grant types: (all)
Login redirect URIs: the full URL to Special:PluggableAuthLogin, e.g. https://www.example.com/wiki/index.php/Special:PluggableAuthLogin
Login flow: "Redirect to app to initiate login (OIDC compliant)"
Initiate login URI: the full URL to Special:UserLogin, e.g. https://www.example.com/wiki/index.php/Special:UserLogin

Extension configuration

You must specify the openid, profile, and email scopes to communicate with Okta. If you omit the appropriate scopes, Okta will gladly authenticate your users but will not return any useful claims. 

$wgPluggableAuth_Config[] = [
    'plugin' => 'OpenIDConnect',
    'data' => [
        'providerURL' => 'https://your-okta-org.okta.com',
        'clientID' => '(paste the client ID Okta assigned your new app here)',
        'clientsecret' => '(paste the client secret Okta assigned your new app here)'
     ]
 ];

Auto-creating users

If you want to take advantage of MediaWiki's user auto-creation (e.g. $wgGroupPermissions['*']['autocreateaccount'] = true;), be aware that Okta's preferred_username claims take the format of an email address.

If you do not want your users to have an @ character in their usernames (this is forbidden by MediaWiki by default), you will need to specify an alternative claim to use via the 'preferred_username' key in your $wgPluggableAuth_Config.

Allowing @ in usernames may break your wiki's Interwiki compatibility (if you rely on that). To allow the use of the @ character, just set $wgInvalidUsernameCharacters = ' '; and $wgUserrightsInterwikiDelimiter = '#'; in LocalSettings.php.

Notes

Uwaga Uwaga: As of the date this example was written, a bug exists in the OpenID Connect PHP library which causes stricter OIDC providers like Okta to reject certain requests. This should be resolved in the future when the library is updated to incorporate the change. The solution is to add a single line of code to $MEDIAWIKI_ROOT/extensions/OpenIDConnect/vendor/jumbojett/openid-connect-php/src/OpenIDConnectClient.php as follows: right below: unset($token_params['client_secret']); simply add: unset($token_params['client_id']); # see https://github.com/jumbojett/OpenID-Connect-PHP/pull/208/commits/dd44c1ca7e45d35dcd8f32ea503b545149bc6562 (this was fixed in version 0.9.8)

To authenticate your users against Okta, you must first create a new OIDC app in your Okta org and assign it to the relevant users/groups, etc.

Znane problemy

  • Wikis that use URLs of the form https://example.org/w/index.php?title=Page_title (i.e. having the page title provided as a query parameter) will not be redirected correctly to complete the authentication flow. Instead, URLs must be of the form https://example.org/w/index.php/Page_title, which can be accomplished by using short URLs or by setting $wgArticlePath appropriately.
  • This extension may not work correctly with $wgMainCacheType = CACHE_ACCEL;. In this case you also need to set $wgSessionCacheType = CACHE_DB; (see zadanie T147161).
  • This extension does not work on non-standard ports unless you manually update the underlying Openid connect client, see: jumbojett/OpenID-Connect-PHP issue 58 on GitHub. This issue also applies when connecting to other webserver than IIS.
  • When running the createAndPromote.php maintenance script, both the PluggableAuth and OpenID Connect extensions need to be disabled by commenting out their wfLoadExtension() calls.
  • This extension does not support custom well-known endpoints. This means Azure Active Directory B2C's OpenID Connect authentication flow is currently not supported.

Notes

  1. ↑ openid.net: OpenID Provider Configuration Request
  2. ↑ 2.0 2.1 Note that the link for the authorized redirect URI must be localized, e.g if you set your wiki's instance language to 'de' ($wgLanguageCode = 'de';) you need to specify "https://[URLofWiki]/wiki/Spezial:PluggableAuthLogin".
  3. ↑ Uniform Resource Identifier (URI)
  4. ↑ OpenID Connect (OIDC)
  5. ↑ Amazon Web Services (AWS)
