FranceConnect authentication and registration in ForgeRock AM 5

Written by Léonard Moustacchis

FranceConnect is the French national Identity Provider (IDP). This IDP acts as a hub that is connected to third party IDPs: La Poste (Mail service), Ameli (Health agency) , impots.gouv.fr (Tax service). National IDP is not a new concept in Europe where the eIDAS regulation applied for years, for example Fedict in Belgium or gov.uk in UK. Whereas the National IDPs are mostly SAML based (some of them uses the Stork profile) the FranceConnect service is OpenID Connect based.

ForgeRock is a FranceConnect partner.

This article explains the FranceConnect implementation in ForgeRock Access Manager 5.0

First creates an account on FranceConnect here Pas encore inscrit ? Je crée mon compte pour utiliser le service FranceConnect, it takes few minutes.

The only information needed is the callback URL, for example: http://openam.example.com/openam/oauth2c/OAuthProxy.jsp

The clientID « key » and the client secret « secret » will be sent by email.

Then the configuration is done in the admin console of the ForgeRock AM.

Go to Authentication>Modules and create a new OAuth 2.0 / OpenID Connect authentication module.

The following attributes have been mapped: given_name=givenname family_name=sn email=mail. The full FranceConnect attribute list is here: Accédez simplement à vos services publics en ligne avec FranceConnect
