## Tested Versions

* [Authelia]
  * [v4.36.4](https://github.com/authelia/authelia/releases/tag/v4.36.4)
* [Outline]
  * 0.65.2

## Before You Begin

### Common Notes

1. You are *__required__* to utilize a unique client id for every client.
2. The client id on this page is merely an example and you can theoretically use any alphanumeric string.
3. You *__should not__* use the client secret in this example, We *__strongly recommend__* reading the
   [Generating Client Secrets] guide instead.

[Generating Client Secrets]: ../specific-information.md#generating-client-secrets

### Assumptions

This example makes the following assumptions:

* __Application Root URL:__ `https://outline.example.com`
* __Authelia Root URL:__ `https://auth.example.com`
* __Client ID:__ `outline`
* __Client Secret:__ `outline_client_secret`

*__Important Note:__ At the time of this writing [Outline] requires the `offline_access` scope by default. Failure to include this scope will result
in an error as [Outline] will attempt to use a refresh token that is never issued.*

## Configuration

### Application

To configure [Outline] to utilize Authelia as an [OpenID Connect] Provider:

1. Configure the following environment options:
```text
URL=https://outline.example.com
FORCE_HTTPS=true

OIDC_CLIENT_ID=outline
OIDC_CLIENT_SECRET=outline_client_secret
OIDC_AUTH_URI=https://auth.example.com/api/oidc/authorization
OIDC_TOKEN_URI=https://auth.example.com/api/oidc/token
OIDC_USERINFO_URI=https://auth.example.com/api/oidc/userinfo
OIDC_USERNAME_CLAIM=preferred_username
OIDC_DISPLAY_NAME=Authelia
OIDC_SCOPES="openid offline_access profile email"
```

### Authelia

The following YAML configuration is an example __Authelia__
[client configuration](../../../configuration/identity-providers/open-id-connect.md#clients) for use with [Outline]
which will operate with the above example:

```yaml
- id: outline
  description: Outline
  secret: '$plaintext$outline_client_secret'
  public: false
  authorization_policy: two_factor
  redirect_uris:
    - https://outline.example.com/auth/oidc.callback
  scopes:
    - openid
    - offline_access
    - profile
    - email
  userinfo_signing_algorithm: none
```
