:::info This documentation lists only the settings that you need to change from their default values. Be aware that any changes other than those explicitly mentioned in this guide could cause issues accessing your application. :::

authentik configuration

To support the integration of HedgeDoc with authentik, you need to create an application/provider pair in authentik.

Create an application and provider in authentik

  1. Log in to authentik as an administrator and open the authentik Admin interface.
  2. Navigate to Applications > Applications and click Create with Provider to create an application and provider pair. (Alternatively you can first create a provider separately, then create the application and connect it with the provider.)
  • Application: provide a descriptive name, an optional group for the type of application, the policy engine mode, and optional UI settings.
  • Choose a Provider type: select OAuth2/OpenID Connect as the provider type.
  • Configure the Provider: provide a name (or accept the auto-provided name), the authorization flow to use for this provider, and the following required configurations.
    • Note the Client ID, Client Secret, and slug values because they will be required later.
    • Set a Strict redirect URI to https://hedgedoc.company/auth/oauth2/callback.
    • Select any available signing key.
  • Configure Bindings (optional): you can create a binding (policy, group, or user) to manage the listing and access to applications on a user's My applications page.
  1. Click Submit to save the new application and provider.
