# OIDC Provider Configuration

This page collects high-level setup steps on how to configure an OIDC
application for various providers. For more general usage and operation
information, see the [Vault JWT/OIDC method documentation](https://www.vaultproject.io/docs/auth/jwt.html).

OIDC providers are often highly configurable and you should become familiar with
their recommended settings and best practices. The instructions below are
largely community-driven and intended to help you get started. Corrections
and additions may be submitted via the [Vault Github repository](https://github.com/hashicorp/vault).

## Azure Active Directory (AAD)
Reference: [Azure Active Directory v2.0 and the OpenID Connect protocol](https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-protocols-oidc)

1. Register or select an AAD application. Visit Overview page.
1. Configure Redirect URIs ("Web" type). 
    * You may include two redirect URIs, one for CLI access another one for Vault UI access.
       * http://localhost:8250/oidc/callback
       * https://hostname:port_number/ui/vault/auth/oidc/oidc/callback
1. Record "Application (client) ID" as you will need it as the oidc_client_id
1. Under API Permissions grant the following permission:
    * Microsoft Graph API permission [Group.Read.All](https://docs.microsoft.com/en-us/graph/permissions-reference#application-permissions-10)  
1. Under "Endpoints", copy the OpenID Connect metadata document URL, omitting the `/well-known...` portion.
    * The endpoint url (oidc_discovery_url) will look like: https://login.microsoftonline.com/tenant-guid-dead-beef-aaaa-aaaa/v2.0
1. Switch to Certificates & Secrets. Create a new client secret and record the generated value as
it will not be accessible after you leave the page.

Please note [Azure AD v2.0 endpoints](https://docs.microsoft.com/en-gb/azure/active-directory/develop/azure-ad-endpoint-comparison)
are required for [external groups](https://www.vaultproject.io/docs/secrets/identity/index.html#external-vs-internal-groups) to work.

* `groupMembershipClaims` should be changed from `none` in the 
[App registration manifest](https://docs.microsoft.com/en-us/azure/active-directory/develop/reference-app-manifest).
Options are "All" or "Security"

* In the [OIDC Role config](https://www.vaultproject.io/api/auth/jwt/index.html#create-role) 
the scope `"https://graph.microsoft.com/.default"` should be added to add groups 
to the jwt token and `groups_claim` should be set to `groups`. 

* Finally Azure AD group can be referenced by using the groups `objectId` as the [group alias name](https://www.vaultproject.io/api/secret/identity/group-alias.html) for the external group.

### CLI setup instructions:
You have to fill in the following values make sure to use the correct vault secret 
path that matches the name of the authentication method such as /oidc/
   * oidc_client_id = Application Client ID
   * oidc_client_secret = Secret obtained from the Certificates & Secrets Section
   * default_role = default role the user will be using when connecting. (see the second command)
   * oidc_discovery_url = Open ID endpoint retrieved from the App Registration wections.
```
vault write auth/oidc/config \
    oidc_client_id="your_client_id" \
    oidc_client_secret="your_client_secret" \
    default_role=“your_default_role” \
    oidc_discovery_url="https://login.microsoftonline.com/tenant_id/v2.0”
```

```
vault write auth/oidc/role/demo user_claim="email" \
    allowed_redirect_uris="http://localhost:8250/oidc/callback,https://online_version_hostname:port_number/ui/vault/auth/oidc/oidc/callback"  \
    groups_claim="groups" \
    policies=default
```

## Auth0
1. Select Create Application (Regular Web App).
1. Configure Allowed Callback URLs.
1. Copy client ID and secret.
1. If you see Vault errors involving signature, check the application's Advanced > OAuth settings
 and verify that signing algorithm is "RS256".

## Gitlab
1. Visit Settings > Applications.
1. Fill out Name and Redirect URIs.
1. Making sure to select the "openid" scope.
1. Copy client ID and secret.

## Google
Main reference: [Using OAuth 2.0 to Access Google APIs](https://developers.google.com/identity/protocols/OAuth2)

1. Visit the [Google API Console](https://console.developers.google.com).
1. Create or a select a project.
1. Create a new credential via Credentials > Create Credentials > OAuth Client ID.
1. Configure the OAuth Consent Screen. Application Name is required. Save.
1. Select application type: "Web Application".
1. Configure Authorized Redirect URIs.
1. Save client ID and secret.

## Keycloak
1. Select/create a Realm and Client. Select a Client and visit Settings.
1. Client Protocol: openid-connect
1. Access Type: confidential
1. Standard Flow Enabled: On
1. Configure Valid Redirect URIs.
1. Save.
1. Visit Credentials. Select Client ID and Secret and note the generated secret.

## Okta

1. Make sure an Authorization Server has been created.
1. Visit Applications > Add Application (Web).
1. Configure Login redirect URIs. Save.
1. Save client ID and secret.

Note your policy will need `oidc_scopes` to include `profile` to get a full profile ("[Fat Token](https://support.okta.com/help/s/article/Okta-Groups-or-Attribute-Missing-from-Id-Token)"). You will also need to configure bound audience along the lines of `"bound_audiences": ["api://default", "0a4........."]` if you are using the default authorization server.
