## Tested Versions

* [Authelia]

* [Nextcloud]
  * 22.1.0

## Before You Begin

{{% oidc-common %}}

### Assumptions

This example makes the following assumptions:

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

*__Important Note:__ it has been reported that some of the [Nextcloud] plugins do not properly encode the client secret.
as such it's important to only use alphanumeric characters as well as the other
[RFC3986 Unreserved Characters](https://datatracker.ietf.org/doc/html/rfc3986#section-2.3). We recommend using the
generating client secrets guidance above.*

## Configuration

### Application

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

1. Install the [Nextcloud OpenID Connect Login app]
2. Add the following to the [Nextcloud] `config.php` configuration:

```php
$CONFIG = array (
    'allow_user_to_change_display_name' => false,
    'lost_password_link' => 'disabled',
    'oidc_login_provider_url' => 'https://auth.example.com',
    'oidc_login_client_id' => 'nextcloud',
    'oidc_login_client_secret' => 'insecure_secret',
    'oidc_login_auto_redirect' => false,
    'oidc_login_end_session_redirect' => false,
    'oidc_login_button_text' => 'Log in with Authelia',
    'oidc_login_hide_password_form' => false,
    'oidc_login_use_id_token' => true,
    'oidc_login_attributes' => array (
        'id' => 'preferred_username',
        'name' => 'name',
        'mail' => 'email',
        'groups' => 'groups',
    ),

);
```

### Authelia

The following YAML configuration is an example __Authelia__
[client configuration](../../../configuration/identity-providers/openid-connect/clients.md) for use with [Nextcloud]
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: 'nextcloud'
      description: 'NextCloud'
      secret: '$pbkdf2-sha512$310000$c8p78n7pUMln0jzvd4aK4Q$JNRBzwAo0ek5qKn50cFzzvE9RXV88h1wJn5KGiHrD0YKtZaR/nCb2CJPOsKaPK0hjf.9yHxzQGZziziccp6Yng'  # The digest of 'insecure_secret'.
      public: false
      authorization_policy: 'two_factor'
      redirect_uris:
        - 'https://nextcloud.example.com/apps/oidc_login/oidc'
      scopes:
        - 'openid'
        - 'profile'
        - 'email'
        - 'groups'
      userinfo_signing_alg: 'none'
```
