# Les layers `authn-*`
|
||||
|
||||
Les layers `authn-*` permettent d'activer différents modes d'authentification au sein d'un proxy Bouncer.
|
||||
|
||||
Les informations liées à l'utilisateur authentifié sont ensuite injectables dans les entêtes HTTP de la requête permettant ainsi une authentification unique("SSO") basée sur les entêtes HTTP ("Trusted headers SSO").
|
||||
|
||||
## Layers
|
||||
|
||||
- [`authn-oidc`](./oidc.md) - Authentification OpenID Connect
|
||||
|
||||
## Schéma des options
|
||||
|
||||
En plus de leurs options spécifiques tous les layers `authn-*` partagent un certain nombre d'options communes.
|
||||
|
||||
Voir le [schéma](../../../../../internal/proxy/director/layer/authn/layer-options.json).
|
||||
|
||||
## Règles d'injection d'entêtes
|
||||
|
||||
L'option `headers.rules` permet de définir une liste de règles utilisant un DSL permettant de définir de manière dynamique quels entêtes seront injectés dans la requête transitant par le layer à destination du service distant.
|
||||
|
||||
La liste des instructions est exécutée séquentiellement.
|
||||
|
||||
Bouncer utilise le projet [`expr`](https://expr-lang.org/) comme DSL. En plus des fonctionnalités natives du langage, Bouncer ajoute un certain nombre de fonction spécifique à son contexte.
|
||||
|
||||
Le comportement des règles par défaut est le suivant:
|
||||
|
||||
1. L'ensemble des entêtes HTTP correspondant au patron `Remote-*` sont supprimés ;
|
||||
2. L'identifiant de l'utilisateur identifié (`user.subject`) est exporté sous la forme de l'entête HTTP `Remote-User` ;
|
||||
3. L'ensemble des attributs de l'utilisateur identifié (`user.attrs`) sont exportés sous la forme `Remote-User-Attr-<name>` où `<name>` est le nom de l'attribut en minuscule, avec les `_` transformés en `-`.
|
||||
|
||||
### Fonctions
|
||||
|
||||
#### `set_header(name string, value string)`
|
||||
|
||||
Définir la valeur d'une entête HTTP via son nom `name` et sa valeur `value`.
|
||||
|
||||
#### `del_headers(pattern string)`
|
||||
|
||||
Supprimer un ou plusieurs entêtes HTTP dont le nom correspond au patron `pattern`.
|
||||
|
||||
Le patron est défini par une chaîne comprenant un ou plusieurs caractères `*`, signifiant un ou plusieurs caractères arbitraires.
|
||||
|
||||
### Environnement
|
||||
|
||||
Les règles ont accès aux variables suivantes pendant leur exécution.
|
||||
|
||||
#### `user`
|
||||
|
||||
L'utilisateur identifié par le layer.
|
||||
|
||||
```json
|
||||
{
|
||||
// Identifiant de l'utilisateur, tel que récupéré par le layer
|
||||
"subject": "<string>",
|
||||
// Table associative des attributs associés à l'utilisateur
|
||||
// La liste de ces attributs dépend du layer d'authentification
|
||||
"attrs": {
|
||||
"key": "<value>"
|
||||
}

}

# Layer `authn-oidc`
|
||||
|
||||
## Description
|
||||
|
||||
Ce layer permet d'ajouter une authentification OpenID Connect au service distant.
|
||||
|
||||
Voir le tutoriel ["Ajouter une authentification OpenID Connect"](../../../tutorials/add-oidc-authn-layer.md) pour plus d'informations quant à son utilisation.
|
||||
|
||||
## Type
|
||||
|
||||
`authn-oidc`
|
||||
|
||||
## Schéma des options
|
||||
|
||||
Les options disponibles pour le layer sont décrites via un [schéma JSON](https://json-schema.org/specification). Elles sont documentées dans le [schéma visible ici](../../../../../internal/proxy/director/layer/authn/oidc/layer-options.json).
|
||||
|
||||
En plus de ces options spécifiques le layer peut également être configuré via [les options communes aux layers `authn-*`](../../../../../internal/proxy/director/layer/authn/layer-options.json).
|
||||
|
||||
## Objet `user` et attributs
|
||||
|
||||
L'objet `user` exposé au moteur de règles sera construit de la manière suivante:
|
||||
|
||||
- `user.subject` sera valué avec la valeur [claim](https://openid.net/specs/openid-connect-core-1_0.html#Claims) `sub` extrait de l'`idToken` récupéré lors de l'authentification ;
|
||||
- `user.attrs` comportera les propriétés suivantes:
|
||||
|
||||
- L'ensemble des `claims` provenant de l'`idToken` seront transposés en `claim_<name>` (ex: `idToken.iss` sera transposé en `user.attrs.claim_iss`) ;
|
||||
- `user.attrs.access_token`: le jeton d'accès associé à l'authentification ;
|
||||
- `user.attrs.refresh_token`: le jeton de rafraîchissement associé à l'authentification (si disponible, en fonction des `scopes` demandés par le client) ;
|
||||
- `user.attrs.token_expiry`: Horodatage Unix (en secondes) associé à la date d'expiration du jeton d'accès ;
|
||||
- `user.attrs.logout_url`: URL de déconnexion pour la suppression de la session Bouncer.
|
||||
|
||||
**Attention** Cette URL ne permet dans la plupart des cas que de supprimer la session côté Bouncer. La suppression de la session côté fournisseur d'identité est conditionné à la présence ou non de l'attribut [`end_session_endpoint`](https://openid.net/specs/openid-connect-session-1_0-17.html#OPMetadata) dans les données du endpoint `.wellknown/openid-configuration`.
|
||||
|
||||
## Métriques
|
||||
|
||||
Les [métriques Prometheus](../../metrics.md) suivantes sont exposées par ce layer.
|
||||
|
||||

# Ajouter une authentification OpenID Connect
|
||||
|
||||
Dans ce tutoriel nous verrons comment ajouter un layer de type `oidc-authn` à un proxy pour ajouter une authentification OpenID Connect à notre service distant.
|
||||
|
||||
## Prérequis
|
||||
|
||||
### Création d'une application OAuth2
|
||||
|
||||
Pour réaliser ce tutoriel nous allons utiliser la forge Cadoles comme fournisseur d'identité. Vous devrez donc créer une application OAuth2 avec votre compte Cadoles sur https://forge.cadoles.com/user/settings/applications et collecter les informations suivantes:
|
||||
|
||||
- Identifiant du client ;
|
||||
- Secret du client.
|
||||
|
||||
Concernant l'URL de redirection, si vous ne modifiez pas l'option `oidc.loginCallbackPath` vous devrez renseigner une URL répondant au modèle suivant:
|
||||
|
||||
```
|
||||
<base_url>/.bouncer/authn/oidc/<proxy_name>/<layer_name>/callback
|
||||
```
|
||||
|
||||
Où
|
||||
|
||||
- `<base_url>` est l'URL de base d'accès à votre instance Bouncer, par exemple `http://localhost:8080` si vous avez travaillez avec une instance Bouncer locale avec la configuration par défaut ;
|
||||
- `<proxy_name>` est le nom du proxy créé dans Bouncer, dans ce tutoriel `my-proxy` ;
|
||||
- `<layer_name>` est le nom du layer créé dans Bouncer, dans ce tutoriel `my-layer`.
|
||||
|
||||
### Démarrer le serveur `dummy` pour l'introspection des entêtes reçus
|
||||
|
||||
Bouncer intègre un serveur de test qui permet l'introspection des entêtes HTTP reçus dans la requête. Nous allons utiliser celui ci comme service distant afin de visualiser les entêtes générés par notre layer d'authentification.
|
||||
|
||||
Pour le lancer:
|
||||
|
||||
```shell
|
||||
# Avec le binaire
|
||||
bouncer server dummy run
|
||||
|
||||
# Avec Docker
|
||||
docker run -it --rm -p 8082:8082 --read-only reg.cadoles.com/cadoles/bouncer:latest bouncer server dummy run
|
||||
```
|
||||
|
||||
Par défaut ce serveur écoute sur le port 8082. Il est possible de modifier l'adresse d'écoute via le drapeau `--address`.
|
||||
|
||||
## Étapes
|
||||
|
||||
1. Avec le client d'administration de Bouncer en ligne de commande, créer un nouveau proxy
|
||||
|
||||
```shell
|
||||
bouncer admin proxy create --proxy-name my-proxy --proxy-to http://localhost:8082
|
||||
```
|
||||
|
||||
Où http://localhost:8082 est l'adresse de notre serveur `dummy` de test, lancé dans les prérequis.
|
||||
|
||||
2. Activer le proxy `my-proxy`
|
||||
|
||||
```shell
|
||||
bouncer admin proxy update --proxy-name my-proxy --proxy-enabled
|
||||
```
|
||||
|
||||
3. À ce stade, vous devriez pouvoir afficher la page du serveur `dummy` en ouvrant l'URL de votre instance Bouncer, par exemple `http://localhost:8080` si vous avez travaillez avec une instance Bouncer locale avec la configuration par défaut
|
||||
|
||||
4. Créer un layer de type `authn-oidc` pour notre nouveau proxy
|
||||
|
||||
```shell
|
||||
bouncer admin layer create --proxy-name my-proxy --layer-name my-layer --layer-type authn-oidc
|
||||
```
|
||||
|
||||
5. Configurer le nouveau layer `my-layer` avec les options collectée dans les prérequis et l'activer
|
||||
|
||||
```shell
|
||||
bouncer admin layer update --proxy-name my-proxy --layer-name my-layer --layer-options '{ "oidc":{"clientId": "<clientId>", "clientSecret":"<clientSecret>", "issuerURL": "https://forge.cadoles.com/" }}' --layer-enabled
|
||||
```
|
||||
|
||||
Où:
|
||||
|
||||
- `<clientId>` est l'identifiant du client OIDC récupéré dans les prérequis ;
|
||||
- `<clientSecret>` est le secret du client OIDC récupéré dans les prérequis.
|
||||
|
||||
6. À ce stade en ouvrant l'URL de votre instance Bouncer vous devriez être redirigé vers la forge Cadoles vous demandant de vous authentifier. Une fois authentifié vous devriez arriver sur la page du serveur `dummy` avec les nouveaux entêtes liés à votre authentification (entêtes `Remote-User-*`).
