Integrate with Ubuntu Landscape

Support level: Community

What is Ubuntu Landscape​

Landscape is a systems management tool developed by Canonical. It can be run on-premises or in the cloud depending on the needs of the user. It is primarily designed for use with Ubuntu derivatives such as Desktop, Server, and Core.

caution

This requires authentik 0.10.3 or newer.

Preparation​

The following placeholders are used in this guide:

  • landscape.company is the FQDN of the Landscape server.
  • authentik.company is the FQDN of the 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.

Landscape uses the OpenID-Connect Protocol for single-sign on.

authentik configuration​

To support the integration of Landscape 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 admin, 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://landscape.company/login/handle-openid.
    • 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.

Landscape configuration​

On the Landscape Server, edit the file /etc/landscape/service.conf and add the following snippet under the [landscape] section:

oidc-issuer = https://authentik.company/application/o/<slug of the application you've created>/
oidc-client-id = <client ID of the provider you've created>
oidc-client-secret = <client Secret of the provider you've created>

Afterwards, run sudo lsctl restart to restart the Landscape services.

Appendix​

To make an OpenID-Connect User admin, you have to insert some rows into the database.

First login with your authentik user, and make sure the user is created successfully.

Run sudo -u postgres psql landscape-standalone-main on the Landscape server to open a PostgreSQL Prompt. Then run select * from person; to get a list of all users. Take note of the ID given to your new user.

Run the following commands to make this user an administrator:

INSERT INTO person_account VALUES (<user id>, 1);
INSERT INTO person_access VALUES (<user id>, 1, 1);
