Azure AD Integration

Azure AD can be integrated via the OIDC integration.

Configure a new Azure AD App registration link

Add a new Azure AD App registration link

1. From the Azure Active Directory > App registrations menu, choose + New registration
2. Enter a Name for the application (e.g. Kluctl Webui).
3. Specify who can use the application (e.g. Accounts in this organizational directory only).
4. Enter Redirect URI (optional) as follows (replacing my-kluctl-webui-url with your Kluctl Webui URL), then choose Add.
   • Platform: Web
   • Redirect URI: https://<my-kluctl-webui-url>/auth/callback
5. When registration finishes, the Azure portal displays the app registration’s Overview pane. You see the Application (client) ID.

   

Add credentials a new Azure AD App registration link

1. From the Certificates & secrets menu, choose + New client secret
2. Enter a Name for the secret (e.g. Kluctl Webui SSO).
   • Make sure to copy and save generated value. This is a value for the oidc-client-secret.

     

Setup permissions for Azure AD Application link

1. From the API permissions menu, choose + Add a permission
2. Find User.Read permission (under Microsoft Graph) and grant it to the created application:

   

3. From the Token Configuration menu, choose + Add groups claim

   

Associate an Azure AD group to your Azure AD App registration link

1. From the Azure Active Directory > Enterprise applications menu, search the App that you created (e.g. Kluctl Webui).
   • An Enterprise application with the same name of the Azure AD App registration is created when you add a new Azure AD App registration.
2. From the Users and groups menu of the app, add any users or groups requiring access to the service.

   

Configure the Kluctl Webui to use the new Azure AD App registration link

Use the following configuration when installing the Webui. Replace occurrences of <directory_tenant_id>, <client_id>, <my-kluctl-webui-url> and <admin_group_id> with the appropriate values from above.

  deployments:
  - path: secrets 
  - git:
      url: https://github.com/kluctl/kluctl.git
      subDir: install/webui
      ref:
         tag: v2.24.1
    vars:
      - values:
          args:
            webui_args:
              - --auth-oidc-issuer-url=https://login.microsoftonline.com/<directory_tenant_id>/v2.0
              - --auth-oidc-client-id=<client_id>
              - --auth-oidc-scope=openid
              - --auth-oidc-scope=profile
              - --auth-oidc-scope=email
              - --auth-oidc-redirect-url=https://<my-kluctl-webui-url>/auth/callback
              - --auth-oidc-group-claim=groups
              - --auth-oidc-admins-group=<admin_group_id>
  

Also, add webui-secrets.yaml inside the secrets subdirectory:

  apiVersion: v1
kind: Secret
metadata:
  name: webui-secret
  namespace: kluctl-system
stringData:
  oidc-client-secret: "<client_secret>"
  

Please note that the client secret is sensitive data and should not be added unencrypted to you git repository. Consider encrypting it via SOPS.
