Automate adding members to Azure Active Directory Group from Databricks: A Step-by-Step Guide

Are you tired of manually adding members to your Azure Active Directory (AAD) group from Databricks? Do you wish there was a way to automate this process and save time? Look no further! In this article, we’ll show you how to automate adding members to AAD group from Databricks using Azure Databricks’ built-in features and Azure Functions.

Prerequisites

Before we dive into the instructions, make sure you have the following prerequisites in place:

• Azure Databricks account with an active cluster
• Azure Active Directory (AAD) with an active directory
• Azure Functions account
• Basic knowledge of Azure Databricks, Azure Active Directory, and Azure Functions

Step 1: Create an Azure Active Directory App and Service Principal

To automate adding members to AAD group from Databricks, we need to create an Azure Active Directory (AAD) app and service principal. This will allow us to authenticate and authorize our Azure Functions to interact with AAD.

1. Log in to your Azure portal and navigate to Azure Active Directory.
2. Click on “App registrations” and then click on “New application.”
3. Enter a name for your app, select “Web” as the platform, and enter a redirect URI.
4. Click on “Register” to create the app.
5. Click on “Certificates & secrets” and click on “New client secret.”
6. Enter a description for the secret and click on “Add.”
7. Copy the client ID and client secret. We’ll need these later.
8. Click on “Overview” and copy the tenant ID. We’ll need this later.

Step 2: Create an Azure Functions App

Next, we need to create an Azure Functions app to automate adding members to AAD group from Databricks.

1. Log in to your Azure portal and navigate to Azure Functions.
2. Click on “Create a function app” and enter a name for your app.
3. Select “consumption plan” as the hosting plan and click on “Create.”
4. Click on “New function” and select “HTTP trigger.”
5. Enter a name for your function, select “Authorization level” as “Anonymous,” and click on “Create.”

Step 3: Configure Azure Functions App to Authenticate with Azure Active Directory

Now, we need to configure our Azure Functions app to authenticate with Azure Active Directory using the service principal we created earlier.

using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Logging;
using Microsoft.Identity.Client;
using System.Net.Http.Headers;

public static void Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = null)] HttpRequestData req,
    ILogger logger)
{
    var clientId = "your_client_id";
    var clientSecret = "your_client_secret";
    var tenantId = "your_tenant_id";

    var app = ConfidentialClientApplicationBuilder.Create(clientId)
        .WithClientSecret(clientSecret)
        .WithTenantId(tenantId)
        .Build();

    var tokenAcquisition = app.AcquireTokenSilentAsync(scopes: new[] { "https://graph.microsoft.com/.default" });
    var token = tokenAcquisition.Result.AccessToken;

    var httpClient = new HttpClient();
    httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

    // Use the authenticated httpClient to call Azure Active Directory APIs
}

Step 4: Write Azure Functions Code to Add Members to AAD Group from Databricks

Now, we need to write the Azure Functions code to add members to AAD group from Databricks.

using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Logging;
using Microsoft.Identity.Client;
using System.Net.Http.Headers;

public static void Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = null)] HttpRequestData req,
    ILogger logger)
{
    // Authenticate with Azure Active Directory using the service principal
    var httpClient = GetAuthenticatedHttpClient();

    // Get the AAD group ID and member UPNs from Databricks
    var groupId = "your_aad_group_id";
    var memberUpns = new string[] { "[email protected]", "[email protected]" };

    // Add members to AAD group using Azure Active Directory Graph API
    foreach (var upn in memberUpns)
    {
        var requestBody = new
        {
            url = $"https://graph.microsoft.com/v1.0/groups/{groupId}/members/$ref",
            data = new
            {
                @odata.id = $"https://graph.microsoft.com/v1.0/users/{upn}"
            }
        };

        var response = httpClient.PostAsJsonAsync("https://graph.microsoft.com/v1.0/$batch", requestBody).Result;

        if (!response.IsSuccessStatusCode)
        {
            logger.LogError($"Failed to add member {upn} to AAD group {groupId}: {response.StatusCode}");
        }
        else
        {
            logger.LogInformation($"Added member {upn} to AAD group {groupId}");
        }
    }
}

private static HttpClient GetAuthenticatedHttpClient()
{
    var clientId = "your_client_id";
    var clientSecret = "your_client_secret";
    var tenantId = "your_tenant_id";

    var app = ConfidentialClientApplicationBuilder.Create(clientId)
        .WithClientSecret(clientSecret)
        .WithTenantId(tenantId)
        .Build();

    var tokenAcquisition = app.AcquireTokenSilentAsync(scopes: new[] { "https://graph.microsoft.com/.default" });
    var token = tokenAcquisition.Result.AccessToken;

    var httpClient = new HttpClient();
    httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

    return httpClient;
}

Step 5: Deploy Azure Functions App and Configure Databricks to Trigger the Function

Now, we need to deploy our Azure Functions app and configure Databricks to trigger the function.

1. Deploy your Azure Functions app to Azure.
2. In Databricks, create a new job and select “Azure Functions” as the trigger type.
3. Enter the URL of your Azure Functions app and select “Add.”
4. Configure the job to run at the desired frequency and click on “Create.”
