This example makes the following assumptions:

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

### Authelia

The following YAML configuration is an example __Authelia__ [client configuration] for use with [Incus]
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: 'incus'
        client_name: 'Incus'
        public: true
        authorization_policy: 'two_factor'
        redirect_uris:
          - 'https://incus.{{< sitevar name="domain" nojs="example.com" >}}/iodc/callback'
        audience:
          - 'https://incus.{{< sitevar name="domain" nojs="example.com" >}}'
        scopes:
          - 'openid'
          - 'offline_access'
        grant_types:
          - 'refresh_token'
          - 'authorization_code'
        access_token_signed_response_alg: 'RS256'
        userinfo_signed_response_alg: 'none'
```

## Application

To configure [Incus] to utilize Authelia as an [OpenID Connect 1.0] Provider:

1. Make sure Web Interface is configured and accessible from `https://incus.{{< sitevar name="domain" nojs="example.com" >}}/`.
2. Set the following configuration options, either via individual commands as shown below or via the `incus config edit` command:
   1. Set `oidc.issuer` to match the Authelia Root URL: `incus config set oidc.issuer https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}`.
   2. Set `oidc.client.id` to match the `client_id` in the Authelia configuration: `incus config set oidc.client.id incus`.
   3. Set `oidc.audience` to match the Application Root URL: `incus config set oidc.audience https://incus.{{< sitevar name="domain" nojs="example.com" >}}`.
3. You should now see a `Login with SSO` button when you access [Incus] Web Interface.

Example finalized config which can be viewed using `incus config show`:

```yaml
config:
  oidc.issuer: https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}
  oidc.client.id: incus
  oidc.audience: https://incus.{{< sitevar name="domain" nojs="example.com" >}}
```
