Apache Guacamole™
What is Apache Guacamole™
From https://guacamole.apache.org/
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
- 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
Under Advanced protocol settings, set the following:
- Token validity: Any value to configure how long the session should last. Guacamole will not accept any tokens valid longer than 300 Minutes.
- Signing Key: Set the key as
authentik Self-signed Certificate
Note the Client ID value. Create an application, using the provider you've created above.
Guacamole
It is recommended you configure an admin account in Guacamole before setting up SSO to make things easier. Create a user in Guacamole using the email address of your user in authentik and give them admin permissions. Without this you might loose access to the Guacamole admin settings and have to revert the settings below.
- Docker
- Standalone
The docker containers are configured via environment variables. The following variables are required:
OPENID_AUTHORIZATION_ENDPOINT: https://authentik.company/application/o/authorize/
OPENID_CLIENT_ID: # client ID from above
OPENID_ISSUER: https://authentik.company/application/o/*Slug of the application from above*/
OPENID_JWKS_ENDPOINT: https://authentik.company/application/o/*Slug of the application from above*/jwks/?exclude_x5
OPENID_REDIRECT_URI: https://guacamole.company/ # This must match the redirect URI above
Standalone Guacamole is configured using the `guacamole.properties` file. Add the following settings:
openid-authorization-endpoint=https://authentik.company/application/o/authorize/
openid-client-id=# client ID from above
openid-issuer=https://authentik.company/application/o/*Slug of the application from above*/
openid-jwks-endpoint=https://authentik.company/application/o/*Slug of the application from above*/jwks/?exclude_x5
openid-redirect-uri=https://guacamole.company/ # This must match the redirect URI above
