{{% oidc-common %}}

### Assumptions

This example makes the following assumptions:

* __Application Root URL:__ `https://outline.{{< sitevar name="domain" nojs="example.com" >}}/`
* __Authelia Root URL:__ `https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/`
* __Client ID:__ `outline`
* __Client Secret:__ `insecure_secret`

Some of the values presented in this guide can automatically be replaced with documentation variables.

{{< sitevar-preferences >}}

{{< callout context="caution" title="Important Note" icon="outline/alert-triangle" >}}
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.
{{< /callout >}}

## Configuration

### Authelia

The following YAML configuration is an example __Authelia__ [client configuration] for use with [Outline] which will
operate with the application example:

```yaml {title="configuration.yml"}
identity_providers:
  oidc:
    ## The other portions of the mandatory OpenID Connect 1.0 configuration go here.
    ## See: https://www.authelia.com/c/oidc
    clients:
      - client_id: 'outline'
        client_name: 'Outline'
        client_secret: '$pbkdf2-sha512$310000$c8p78n7pUMln0jzvd4aK4Q$JNRBzwAo0ek5qKn50cFzzvE9RXV88h1wJn5KGiHrD0YKtZaR/nCb2CJPOsKaPK0hjf.9yHxzQGZziziccp6Yng'  # The digest of 'insecure_secret'.
        public: false
        authorization_policy: 'two_factor'
        redirect_uris:
          - 'https://outline.{{< sitevar name="domain" nojs="example.com" >}}/auth/oidc.callback'
        scopes:
          - 'openid'
          - 'offline_access'
          - 'profile'
          - 'email'
        userinfo_signed_response_alg: 'none'
