+# How to enable custom identity provider support
+
+The Anbox Cloud Appliance has support for custom identity providers for authentication through the use of [OpenID Connect](https://openid.net/developers/discover-openid-and-openid-connect/).
+
+Support for a custom identity provider has to be enabled at initialisation by using a preseed configuration. See {ref}`ref-appliance-preseed-config` for more details.
+
+Anbox Cloud uses the [authorisation code flow](https://openid.net/specs/openid-connect-core-1_0.html#CodeFlowAuth) to obtain an identity token. No access token is requested in this flow because authorisation is handled within the Anbox Cloud services.
+
+In order to allow discovery of the necessary endpoints on the identity provider, it must support the [OpenID Connect Discovery](https://openid.net/specs/openid-connect-discovery-1_0.html) protocol.
+
+The following will show you how to configure an [OpenID Connect](https://openid.net/developers/discover-openid-and-openid-connect/) based identity provider for the Anbox Cloud Appliance.
+
+## Preparation
+
+In order to configure [OpenID Connect](https://openid.net/developers/discover-openid-and-openid-connect/) based authentication, you will need the following from your identity provider:
+
+* The issuer URL
+* The client ID
+* (Optional) The audience URL, required by some providers. For example, [Auth0](https://auth0.com)
+
+The identity provider is expected to provide the JSON Web Key Set endpoint on `<issuer URL>/.well-known/jwks.json`.
+
+Your identity provider must have `https://<appliance address or <DNS name>/oidc/callback` configured as allowed redirect/callback URL.
+
+## Configure OpenID Connect
+
+It is only possible to configure support for OpenID Connect only when the Anbox Cloud Appliance is being initialised with a preseed (see {ref}`ref-appliance-preseed-config`). The other steps to install the Anbox Cloud Appliance as described in {ref}`tut-installing-appliance` remain the same.
+
+The issuer URL, client ID and optional audience URL are set in the preseed configuration as follows:
+
+```yaml
+$ cat preseed.yaml
+....
+oidc:
+  issuer: https://my.auth.com
+  client_id: aff32f32ffwfsdfdsfdsg
+  # Only if your identity provider requires it
+  audience: https://my.auth.com/api/v2
+```
+
+With the preseed configuration you can initiate the initialisation process by running:
+
+    sudo anbox-cloud-appliance init --preseed < preseed.yaml
+
+Once the initialisation has been completed, you can register a new user by running:
+
+    sudo anbox-cloud-appliance dashboard register <email address>
+
+Once the user has been registered by following the printed URL and authenticated with your identity provider, access is granted to the web UI.
