+
+:::note
+Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH.
+:::
+
+## Preparation
+
+The following placeholders will be used:
+
+- `guacamole.company` is the FQDN of the Guacamole install.
+- `authentik.company` is the FQDN of the authentik install.
+
+Create an OAuth2/OpenID provider with the following parameters:
+
+- Client Type: `Confidential`
+- JWT Algorithm: `RS256`
+- Redirect URIs: `https://guacamole.company/` (depending on your Tomcat setup, you might have to add `/guacamole/` if the application runs in a subfolder)
+- Scopes: OpenID, Email and Profile
+
+Note the Client ID value. Create an application, using the provider you've created above.
