Extension:GoogleLogin/PreAuthManager/nl

De extensie GoogleLogin staat het wiki-gebruikers toe om in te loggen met hun Google Account. De extensie gebruikt de Google-API om de gebruikersgegevens op te vragen. Als de gebruiker voor de eerste keer inlogt, de extensie staat het de gebruiker toe om een gebruiker toe te voegen met het Google e-mailadres en de Google gebruikersnaam (of de gegeven of de eigen naam).

Om deze extensie te gebruiken zijn de volgende onderdelen vereist:
 * MediaWiki 1.23+ (voor versie v0.2.0 en hoger is MediaWiki 1.24 vereist)
 * MySQL (geen ondersteuning voor PostgreSQL of SQLite op dit moment)
 * PHP 5.3+
 * Google Ontwikkelaars Toegang

Aanvullende configuratie parameter


Instellingen in het Google Developer Console
Om deze extensie te gebruiken dient u een Google developer account en toegang tot het developer console te hebben. Dit is een erg eenvoudige gids (gebruik Stap 1 van de officiële gids met deze instellingen):


 * 1) Open het Google developer console
 * 2) Lees en accepteer de voorwaarden
 * 3) Maak uw eerste project aan
 * 4) Ga naar APIS & AUTH
 * 5) Ga naar APIs en schakel Google+ API in (lees eerst de voorwaarden en accepteer die)
 * 6) Ga naar Credentials
 * 7) Klik in de sectie OAuth op Create new Client ID
 * 8) Selecteer Web application als APPLICATION TYPE, bij  Authorized JavaScript origins voer in uw domeinnaam (geen jokertekens of mappen toesgestaan!)
 * 9) Vul uw Authorized redirect URI in zoals in dit voorbeeld:
 * Als example.com de domeinnaam is en u heeft MediaWiki geïnstalleerd in de Root van het domein, dan is de 'redirect URI': http://example.com/index.php/Special:GoogleLogin
 * 1) Maak het aan en kopieer de Client ID en de Client Secret naar de betreffende configuratie-variabelen in LocalSettings.php



"Special:GoogleLogin" (of wat het in de vertaling geworden is)
The allowed redirect URI in Google developer console must be in content language. So, if your wiki has content language German, then type in "Spezial:Mit_Google_anmelden" and not "Special:GoogleLogin". If you used the wrong language, all Authentication requests will fail with redirect uri mismatch.

Debuggen
Normally, you can see the error message on all generic error pages. Sometimes there are Internal Errors, called Exceptions. In this case, please add with value true in   to see the complete Exception message. For a support request, please provide always the lines of the Exception.



Gebruik op een privé wiki
If you have set your Wiki to private with

you have to whitelist the "Special:GoogleLogin" page, so that anonymous users can access the callback URL after being redirected from the authentication provider. You can do this by adding the following line to your LocalSettings.php:

Allow account creation only via GoogleLogin
It's possible to deactivate the account creation function of MediaWiki. Normally GoogleLogin don't give the option to create a new account, too. It's possible to change this, that Users can still create an account with GoogleLogin, but can't with the vanilla account creation form. For this you need to set up the following configuration varaibles in your :

If you want to remove the Login form of MediaWiki, too, you can set this configuration variable, too:

If you want to remove GoogleLogin in the future for any reason, your users can still login into your MediaWiki installation without to register a new account. GoogleLogin creates normal MediaWiki-accounts with a random password. Your users just have to reset their password with the special page Special:PasswordReset.

<-> GoogleLogin conflict (only with and MediaWiki <= 1.26!)
MobileFrontend, the extension to provide a mobile optimized version of your wiki, actually conflicts with GoogleLogin if you set  to   (to disallow login with the vanilla login form). In the case, that MobileFrontend is loaded after GoogleLogin (the require_once line of MobileFrontend in your  is after the one of GoogleLogin), the special page UserLogin (which handles the login with username and password) will be overwritten by GoogleLogin the first time and by MobileFrontend the second time (to provide a mobile optimized login page). In this case, MobileFrontends Replacement will win and mobile users can still login with username and passwords.

Actually this problem is solved in the MediaWiki release branch/version 1.26 (tracked in ) of MobileFrontend. For older versions of MediaWiki/MobileFrontend you need to change the order in which the Extensions are loaded. Put the require_once and configuration lines of GoogleLogin somewhere after the ones of MobileFrontend in your. This workaround should be obsolete in one of the next versions of MobileFrontend.



Wat deze extensie kan doen
With the database update, the extension will create a new table called prefix_user_google_user which contains the needed connection between the wiki users and Google accounts. It stores only the Google UserId and the Wiki UserId.

If a user calls the special page GoogleLogin, they will instantly redirected to Google Authentication request to give your application access to some user information stored by Google. The user must accept this request (or they can not use the login with Google). After accepting, the user has the possibility, if they are not logged in as a wiki user, to create a new account. The username they can choose self or choose one of the suggestions, based on the Google user name and given name (if one s free and createable). If the chosen username is creatable (free, valid and not blocked), a new user with the username and the Google-Mail as e-mail-address will be created and linked to the Google Account.

If the user is logged in (means: they have already a wiki account) they can link this account with the Google account, this the user must do only once. If the connection is created, the user will be able to login simply by clicking Login with Google button on Special:Login.

If the wiki account and Google account is connected, the user can, if they navigate to "Special:GoogleLogin", unlink his account and Google account.

Google API PHP Client
This Extension uses the Google API PHP Client (included in versions before 0.2.1), distributed under the Apache 2.0 License. The Client can be downloaded from GitHub.
