Authenticate with Microsoft Entra ID via OIDC

Authenticate Kestra users with their Microsoft Entra ID credentials using OIDC.

Configure Microsoft OIDC

To authenticate with Microsoft, add the following to your Micronaut configuration:

micronaut:
  security:
    oauth2:
      enabled: true
      clients:
        microsoft:
          client-id: "{{ clientId }}"
          client-secret: "{{ clientSecret }}"
          openid:
            issuer: 'https://login.microsoftonline.com/common/v2.0/'

To get your client-id and client-secret, refer to the Microsoft Documentation.

Using Microsoft Entra ID as an OIDC provider

Create an Enterprise Application

1. Visit the Azure portal.
2. Select Microsoft Entra ID.
3. Navigate to App registrations.
4. Click on New registration and provide the necessary details:
   • Enter a name for your application.
   • Set Supported account types (e.g., “Default Directory only - Single tenant”).
   • Under Redirect URI, select Web and enter https://{{ url }}/oauth/callback/microsoft. Use https and your actual webserver URL.

Generate client secret

1. Go to Certificates & secrets.
2. Under Client secrets, click on New client secret.
3. Copy the generated secret and use it in the {{ clientSecret }} field in your Security and Secrets configuration.

Kestra configuration

• Copy the Application (client) ID from the Overview section and use it as your {{ clientId }}.
• In the Endpoints section, locate the OpenID Connect metadata document URL. Remove the .well-known/openid-configuration suffix, and use the remaining base URL as your {{ issuerUrl }}.

The final URL should look like https://login.microsoftonline.com/{{ directory }}/v2.0/.

Example configuration:

micronaut:
  security:
    oauth2:
      enabled: true
      clients:
        microsoft:
          client-id: "{{ clientId }}"
          client-secret: "{{ clientSecret }}"
          openid:
            issuer: '{{ issuerUrl }}'

Replace all placeholders with the values obtained from Entra ID.
