# Casdoor ## Backend class For Django, add this class path to `AUTHENTICATION_BACKENDS`. For other integrations, use the same class path in the framework-specific backend setting. | Backend name | Class path | |----------------|-----------------------------------------------------| | `casdoor` | `social_core.backends.casdoor.CasdoorOpenIdConnect` | The [Casdoor](https://casdoor.org/) backend authenticates against a self-hosted Casdoor server using OpenID Connect. In Casdoor, open your application and add your callback URL, typically `https://your-domain.com/complete/casdoor/`, to **Redirect URLs**. Then copy the application’s **Client ID** and **Client secret** and configure: ```default SOCIAL_AUTH_CASDOOR_OIDC_ENDPOINT = 'https://door.example.com' SOCIAL_AUTH_CASDOOR_KEY = '' SOCIAL_AUTH_CASDOOR_SECRET = '' ``` The endpoint is the base URL of your Casdoor server. Do not append `/.well-known/openid-configuration`. Trailing slashes are normalized. The remaining configuration is auto-detected by fetching: ```default /.well-known/openid-configuration ``` ## User details The Casdoor backend inherits defaults from `open_id_connect.py`. Casdoor returns the user’s name in the `preferred_username` claim, which is used as the username, and the display name in the `name` claim. Accounts are bound to the stable `sub` claim, which is the Casdoor user ID. See the [Casdoor OIDC client documentation](https://casdoor.org/docs/how-to-connect/oidc-client) for the full list of claims. The default scopes are `openid`, `profile` and `email`. You can request additional scopes like this: ```default SOCIAL_AUTH_CASDOOR_SCOPE = ['phone'] ```
