+
+## What is Drupal
+
+> Drupal is a free and open-source content management system written in PHP and
+> paired with a database.
+>
+> -- https://en.wikipedia.org/wiki/Drupal
+
+:::note
+There are many different modules for Drupal that allow you to set up SSO using
+different authentication methods. This tutorial uses the
+[OpenID Connect / OAuth client](https://www.drupal.org/project/openid_connect)
+module.
+:::
+
+## Preparation
+
+The following placeholders are used in this guide:
+
+- `drupal.company` is the FQDN of Drupal installation.
+- `authentik.company` is the FQDN of authentik installation.
+
+:::note
+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
+
+### Provider
+
+1. Go to Applications -> Providers
+   https://authentik.company/if/admin/#/core/providers
+2. Create an OAuth2/OpenID Provider
+3. Set the Authentication flow to default-authentication-flow
+4. The Authorisation flow can be either default-provider-authorization-implicit-consent
+   or default-provider-authorization-explicit-consent
+5. Set the Client type to "Confidential"
+6. Note the Cliend ID and Client Secret
+7. Set the Redirect URIs/Origins to your Drupal site
+   https://drupal.company/openid-connect/generic
+8. Leave everything else as-is
+
+### Application
+
+1. Go to Applications -> Applications
+   https://authentik.company/if/admin/#/core/applications
+2. Create an application e.g. "Drupal" and set the Provider field to the provider
+   created above
+
+## Drupal configuration
+
+1. From the Admin Toolbar or admin page at https://drupal.company/admin go to
+   **Configuration -> Web Services -> OpenID Connect** or directly at https://drupal.company/admin/config/services/openid-connect.
+2. Input the Client ID and Secret you noted above.
+3. Fill out the following endpoints:
+
+- **Authorization endpoint**: <kbd>https://<em>authentik.company</em>/application/o/authorize/</kbd>
+- **Token endpoint**: <kbd>https://<em>authentik.company</em>/application/o/token/</kbd>
+- **UserInfo endpoint**: <kbd>https://<em>authentik.company</em>/application/o/userinfo/</kbd>
+
+4. If your User Registration settings (**Admin -> Configuration -> People -> Account Settings** or
+   https://drupal.company/admin/config/people/accounts) does not allow new users, check the "Override registration
+   settings" checkbox to enable new accounts to be created. If you do not check this and log in as an unknown user, you
+   will get a message saying you've successfully logged in but your account is blocked and needs to be approved by
+   an administrator. Individual accounts can be unblocked at **Admin -> People** or https://drupal.company/admin/people.
+
+:::info
+If you are developing Drupal locally with DDEV and authentik is also running
+locally, use `host.docker.internal:9000` as the hostname for the Token and UserInfo endpoints.
+::: 5. Enable the OpenID button on the user login form.
+
+## Configuration verification
+
+To confirm that authentik is properly configured with Drupal, log out from the
+Admin Toolbar link under your username, or go directly to
+https://drupal.company/user/logout, and log back in via authentik at https://drupal.company/user/login.
