### Assumptions

This example makes the following assumptions:

* __Application Root URL:__ `https://gitea.{{< sitevar name="domain" nojs="example.com" >}}/`
* __Authelia Root URL:__ `https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/`
* __Client ID:__ `gitea`
* __Client Secret:__ `insecure_secret`
* __Authentication Name (Gitea):__ `authelia`:
    * This option determines the redirect URI in the format of
      `https://gitea.{{< sitevar name="domain" nojs="example.com" >}}/user/oauth2/<Authentication Name>/callback`.
      This means if you change this value you need to update the redirect URI.

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

## Configuration

### Authelia

The following YAML configuration is an example __Authelia__ [client configuration] for use with [Gitea] 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: 'gitea'
        client_name: 'Gitea'
        client_secret: '$pbkdf2-sha512$310000$c8p78n7pUMln0jzvd4aK4Q$JNRBzwAo0ek5qKn50cFzzvE9RXV88h1wJn5KGiHrD0YKtZaR/nCb2CJPOsKaPK0hjf.9yHxzQGZziziccp6Yng'  # The digest of 'insecure_secret'.
        public: false
        authorization_policy: 'two_factor'
        redirect_uris:
          - 'https://gitea.{{< sitevar name="domain" nojs="example.com" >}}/user/oauth2/authelia/callback'
        scopes:
          - 'openid'
          - 'email'
          - 'profile'
        userinfo_signed_response_alg: 'none'
        token_endpoint_auth_method: 'client_secret_basic'
```

### Application

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

1. Expand User Options
2. Visit Site Administration
3. Visit Authentication Sources
4. Visit Add Authentication Source
5. Configure:
   1. Authentication Name: `authelia`
   2. OAuth2 Provider: `OpenID Connect`
   3. Client ID (Key): `gitea`
   4. Client Secret: `insecure_secret`
   5. OpenID Connect Auto Discovery URL: `https://{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}/.well-known/openid-configuration`

{{< figure src="gitea.png" alt="Gitea" width="300" >}}

To configure [Gitea] to perform automatic user creation for the `{{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}` domain via [OpenID Connect 1.0]:

1. Edit the following values in the [Gitea] `app.ini`:
```ini
[openid]
ENABLE_OPENID_SIGNIN = false
ENABLE_OPENID_SIGNUP = true
WHITELISTED_URIS     = {{< sitevar name="subdomain-authelia" nojs="auth" >}}.{{< sitevar name="domain" nojs="example.com" >}}

[service]
DISABLE_REGISTRATION                          = false
ALLOW_ONLY_EXTERNAL_REGISTRATION              = true
SHOW_REGISTRATION_BUTTON                      = false
```
