# ORY Kratos as Login Provider for ORY Hydra

> **Warning:** this is a preliminary example and will properly be implemented
> in ORY Kratos directly.

For now, to run this example execute:

```shell script
docker-compose up --build
```

Next, create an OAuth2 Client

```shell script
docker-compose exec hydra \
    hydra clients create \
    --endpoint http://127.0.0.1:4445 \
    --id auth-code-client \
    --secret secret \
    --grant-types authorization_code,refresh_token \
    --response-types code,id_token \
    --scope openid,offline \
    --callbacks http://127.0.0.1:5555/callback
```

and perform an OAuth2 Authorize Code Flow

```shell script
docker-compose exec hydra \
    hydra token user \
    --client-id auth-code-client \
    --client-secret secret \
    --endpoint http://hydra.server.lan/ \
    --port 5555 \
    --scope openid,offline
```

## Setup

Clone the ui:

```shell script
./setup.sh
```

Spin the containers:

```shell script
docker-compose build --pull && docker-compose up -d
```

## Gitea

Create an OAuth2 Client

```shell script
docker-compose exec hydra \
    hydra clients create \
    --endpoint http://127.0.0.1:4445 \
    --id gitea-client \
    --secret superSecret \
    --grant-types authorization_code,refresh_token \
    --response-types code,id_token \
    --scope openid,offline \
    --callbacks http://git.dev.server.lan/user/oauth2/hydra/callback
```

and perform an OAuth2 Authorize Code Flow

```shell script
docker-compose exec hydra \
    hydra token user \
    --client-id gitea-client \
    --client-secret superSecret \
    --endpoint http://hydra.server.lan/ \
    --port 5555 \
    --scope openid,offline
```

## Nextcloud

```shell script
hydra clients create \
    --endpoint http://127.0.0.1:4445 \
    --id nextcloud \
    --secret superSecret \
    --grant-types authorization_code,refresh_token \
    --response-types code,id_token \
    --scope openid,offline \
    --callbacks http://cloud.server.lan/apps/oidc_login/oidc
```

Minimum parameters needed in `config/config.php`:

```php
'oidc_login_client_id' => 'nextcloud',
'oidc_login_client_secret' => 'superSecret',
'oidc_login_provider_url' => 'http://hydra.server.lan',
'oidc_login_disable_registration' => false,
'oidc_login_attributes' => array(
        'id' => 'sub',
),
```
