# Agent Connect

## Presentation

Agent Connect is an authentication platform made by French government for people working for the state. It relies on OpenID Connect protocol.

To select on which Identity Provider the user will be redirected, Agent Connect relies on the email domain :

Tip

All users of an email domain will use the same Identity Provider.

LemonLDAP::NG can be used as Relying Party or OpenID Provider for Agent Connect.

Official documentation is available on Github.

## LL::NG as OpenID Provider

### Registration on Agent Connect

As noticed in the official documentation, you need to fill a form to request the authorization of using Agent Connect.

You will provide one or more mail domains that will be associated with your Identity Provider.

Once the configuration is done on LL::NG, you will send them the client ID, client secret and OIDC metadata URL.

### Configuration on LemonLDAP::NG

Add Agent Connect as Relying Party, with these options:

- Client ID / Client Secret: generate random values

- Redirect URIs: https://auth.agentconnect.gouv.fr/api/v2/oidc-callback

- Redirect Logout URIs: https://auth.agentconnect.gouv.fr/api/v2/client/logout-callback

- Exported attributes:

  - email (mandatory)

  - given_name (mandatory)

  - name (mandatory)

  - organizational_unit (must not contain some special characters, listed in this regex /^[^.*?{}()|[]trn\]*$/)

  - phone

  - preferred_username

  - siret

  - uid (mandatory, must contain only ASCII characters)

  - usual_name (mandatory)

- User attribute: be sure to choose a unique and persistent attribute

- ID Token signature algorithm: RS256

- UserInfo response format: JWT/RS256

- Scope / Scope value contents:

  - given_name: given_name

  - organizational_unit: organizational_unit

  - phone: phone

  - siret: siret

  - uid: uid

  - usual_name: usual_name

To match authencation levels required by Agent Connect, you must adapt the corresponding levels in OpenID Connect Service > Authentication context. You need at least the eidas1 level.
