Integrate with Kimai

Support level: Community

What is Kimai​

Kimai is a free & open source timetracker. It tracks work time and prints out a summary of your activities on demand. Yearly, monthly, daily, by customer, by project … Its simplicity is its strength. Due to Kimai's browser based interface it runs cross-platform, even on your mobile device.

Preparation​

The following placeholders are used in this guide:

  • kimai.company is the FQDN of the Kimai Install
  • authentik.company is the FQDN of the authentik Install
  • admin.group is the authentik group to be made Admin in Kimai
info

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.

authentik configuration​

To support the integration of Kimai 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 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://kimai.company/auth/saml/acs.
      • Set the Issuer to https://authentik.company.
      • Set the Service Provider Binding to Post.
      • Set the Audience to https://kimai.company/auth/saml.
      • Under Advanced protocol settings:
        • Select an available Signing certificate.
        • Set NameID Property Mapping to authentik default SAML MApping: Email.
        • Set Default NameID Policy to Email Address.
    • 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.

Download certificate file​

  1. Log in to authentik as an administrator and open the authentik Admin interface.
  2. Navigate to Applications > Providers and click on the name of the provider that you created in the previous section.
  3. Under Related objects > Download signing certificate, click on Download. This is your certificate file and its contents will be required in the next section.

Kimai Configuration​

Paste the following block in your local.yaml file, after replacing the placeholder values from above. The file is usually located in /opt/kimai/config/packages/local.yaml.

The value for x509cert is the content of the certificate file downloaded in the previous section.
