Keycloak SSO with QuFabric Self-Hosted (Advanced)

Keycloak is an open-source Identity and Access Management solution maintained by Red Hat. It provides single sign-on, social login, user federation, fine-grained authorization, and supports OpenID Connect, OAuth 2.0, and SAML 2.0 protocols.

Standalone Setup (Advanced)

QuFabric includes built-in local user management powered by an embedded IdP, allowing you to create and manage users directly without requiring an external identity provider. You can also add multiple external identity providers alongside local users, giving users multiple login options.

We highly recommend using the simpler setup that adds Keycloak as an external IdP directly in the QuFabric Management Dashboard. This approach requires minimal configuration, works alongside local users, and doesn't require replacing your embedded IdP. See the Management Setup (Recommended) section in the main Keycloak documentation.

The standalone setup below replaces your embedded IdP entirely and is only recommended for experienced Keycloak administrators who need full control over authentication and user management.

Use Keycloak as your primary identity provider instead of QuFabric's embedded IdP. This option gives you full control over authentication and user management, is recommended for experienced Keycloak administrators as it also requires additional setup and ongoing maintenance.

For most deployments, the embedded IdP is the simpler choice — it's built into QuFabric, fully integrated, and requires minimal configuration to get started. For this implementation, go back up to the Management Setup (Recommended) section above.

If you prefer not to self-host an Identity and Access Management solution, you could use a managed alternative like Auth0.

Expected Result

After completing this guide, you can log in to your self-hosted QuFabric Dashboard and add machines to your network using the Interactive SSO Login feature over Keycloak.

Optional: To enable automatic user deletion from Keycloak when deleted from QuFabric, add the --user-delete-from-idp flag to the management startup command and assign the manage-users role instead.

Step 10: Configure QuFabric

Your authority OIDC configuration will be available at:

https://<YOUR_KEYCLOAK_HOST_AND_PORT>/realms/qufabric/.well-known/openid-configuration

Double-check if the endpoint returns a JSON response by calling it from your browser.

Set properties in the setup.env file:

QUFABRIC_AUTH_OIDC_CONFIGURATION_ENDPOINT="https://<YOUR_KEYCLOAK_HOST_AND_PORT>/realms/qufabric/.well-known/openid-configuration"
QUFABRIC_USE_AUTH0=false
QUFABRIC_AUTH_CLIENT_ID="qufabric-client"
QUFABRIC_AUTH_SUPPORTED_SCOPES="openid profile email offline_access api"
QUFABRIC_AUTH_AUDIENCE="qufabric-client"

QUFABRIC_AUTH_DEVICE_AUTH_CLIENT_ID="qufabric-client"
QUFABRIC_AUTH_DEVICE_AUTH_AUDIENCE="qufabric-client"

QUFABRIC_MGMT_IDP="keycloak"
QUFABRIC_IDP_MGMT_CLIENT_ID="qufabric-backend"
QUFABRIC_IDP_MGMT_CLIENT_SECRET="<QUFABRIC_BACKEND_CLIENT_SECRET>"
QUFABRIC_IDP_MGMT_EXTRA_ADMIN_ENDPOINT="https://<YOUR_KEYCLOAK_HOST_AND_PORT>/admin/realms/qufabric"

Make sure your Keycloak instance uses HTTPS. Otherwise, the setup won't work.

Step 11: Continue with QuFabric Setup

You've configured all required resources in Keycloak. Continue with the QuFabric Self-hosting Guide.

Troubleshooting

"Invalid token" errors

  • Verify the issuer URL includes /realms/your-realm
  • Ensure the client ID matches in both Keycloak and QuFabric
  • Check clock synchronization between servers

Users not appearing in QuFabric

  • Verify the backend client has view-users role
