## Before You Begin

{{% oidc-common %}}

### Assumptions

This example makes the following assumptions:

* __Application Root URL:__ `https://gitea.example.com`
* __Authelia Root URL:__ `https://auth.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.example.com/user/oauth2/<Authentication Name>/callback`.
      This means if you change this value you need to update the redirect URI.

## Configuration

### 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://auth.example.com/.well-known/openid-configuration`

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

To configure [Gitea] to perform automatic user creation for the `auth.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     = auth.example.com

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

Take a look at the [See Also](#see-also) section for the cheatsheets corresponding to the sections above for their
descriptions.

### Authelia

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

```yaml
identity_providers:
  oidc:
    ## The other portions of the mandatory OpenID Connect 1.0 configuration go here.
    ## See: https://www.authelia.com/c/oidc
    clients:
    - id: 'gitea'
      description: 'Gitea'
      secret: '$pbkdf2-sha512$310000$c8p78n7pUMln0jzvd4aK4Q$JNRBzwAo0ek5qKn50cFzzvE9RXV88h1wJn5KGiHrD0YKtZaR/nCb2CJPOsKaPK0hjf.9yHxzQGZziziccp6Yng'  # The digest of 'insecure_secret'.
      public: false
      authorization_policy: 'two_factor'
      redirect_uris:
        - 'https://gitea.example.com/user/oauth2/authelia/callback'
      scopes:
        - 'openid'
        - 'email'
        - 'profile'
      userinfo_signing_alg: 'none'
```
