Integrate with TrueNAS TrueCommand

What is TrueNAS TrueCommand

TrueCommand is a ZFS-aware solution allowing you to set custom alerts on statistics like ARC usage or pool capacity and ensuring storage uptime and future planning. TrueCommand also identifies and pinpoints errors on drives or vdevs (RAID groups), saving you valuable time when resolving issues.

authentik configuration

To support the integration of TrueCommand with authentik, you need to create an application/provider pair in authentik.

Create property mappings

1. Log in to authentik as an administrator and open the authentik Admin interface.
2. Navigate to Customization > Property Mappings and click Create. Create create three or five SAML Provider Property Mappings, depending on your setup, with the following settings:
   • Username Mapping:
     • Name: Choose a descriptive name
     • SAML Attribute Name: unique_name
     • Friendly Name: Leave blank
     • Expression: return request.user.username
   • Email Mapping:
     • Name: Choose a descriptive name
     • SAML Attribute Name: email
     • Friendly Name: Leave blank
     • Expression: return request.user.email
   • Name Mapping:
     • Name: Choose a descriptive name
     • SAML Attribute Name: given_name or display_name
     • Friendly Name: Leave blank
     • Expression: return request.user.name
   • Title Mapping:
     • Name: Choose a descriptive name
     • SAML Attribute Name: title
     • Friendly Name: Leave blank
     • Expression: return [custom_attribute]
   • Telephone Number Mapping:
     • Name: Choose a descriptive name
     • SAML Attribute Name: telephone_number
     • Friendly Name: Leave blank
     • Expression: return [custom_attribute]

Create an application and provider in authentik

1. Log in to authentik as an administrator 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. Take note of the slug as it will be required later.
• Choose a Provider type: select SAML Provider 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.
  • Set the ACS URL to https://truecommand.company/saml/acs.
  • Set the Issuer to truecommand-saml.
  • Set the Service Provider Binding to Post.
  • Under Advanced protocol settings, add the three or five Property Mappings you created in the previous section, then set the NameID Property Mapping to be based on the user's email. Finally, select an available Signing certificate.
• 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.

3. Click Submit to save the new application and provider.

4. Navigate to Applications > Providers > Provider, then click Copy download URL to save the metadata URL to your clipboard.
