There's a newer version of this sample! Check it out: https://github.com/azure-samples/ms-identity-javascript-graphapi

This newer sample takes advantage of the Microsoft identity platform (formerly Azure AD v2.0).

While still in public preview, every component is supported in production environments

This sample demonstrates the use of ADAL for JavaScript for securing an AngularJS based single page app, implemented with an ASP.NET Web API backend.

ADAL for Javascript is an open source library. For distribution options, source code, and contributions, check out the ADAL JS repo at https://github.com/AzureAD/azure-activedirectory-library-for-js.

For more information about how the protocols work in this scenario and other scenarios, see Authentication Scenarios for Azure AD.

How To Run This Sample

Getting started is simple! To run this sample you will need: - Visual Studio 2013 - An Internet connection - An Azure Active Directory (Azure AD) tenant. For more information on how to get an Azure AD tenant, please see How to get an Azure AD tenant - A user account in your Azure AD tenant. This sample will not work with a Microsoft account, so if you signed in to the Azure portal with a Microsoft account and have never created a user account in your directory before, you need to do that now.

Step 1: Clone or download this repository

From your shell or command line: git clone https://github.com/Azure-Samples/active-directory-angularjs-singlepageapp.git

Step 2: Register the sample with your Azure Active Directory tenant

  1. Sign in to the Azure portal.
  2. On the top bar, click on your account and under the Directory list, choose the Active Directory tenant where you wish to register your application.
  3. From the left hand navigation pane, choose Azure Active Directory.
  4. Click on App registrations and choose New registration.
  5. When the Register an application page appears, enter your application's registration information:
    • Enter a friendly name for the application, for example 'SinglePageApp-DotNet'.
    • Leave Supported account types on Accounts in this organizational directory only
    • For the Redirect URI (optional), enter the base URL for the sample, which is by default https://localhost:44326/.
  6. Click on Register to create the application.
  7. On the following app Overview page, find the Application (client) ID value and record it for later. You'll need it to configure the Visual Studio configuration file for this project.
  8. [Optional] Next, if you are tenant admin, you can grant permissions across your tenant for your application. Go to API Permissions, and then choose Grant admin consent for button. Click Yes to confirm.

Step 3: Enable the OAuth2 implicit grant for your application

By default, applications provisioned in Azure AD are not enabled to use the OAuth2 implicit grant. In order to run this sample, you need to explicitly opt in.

  1. From the former steps, your browser should still be on the Azure portal.
  2. From the application page, click on Authentication, and under Advanced Settings, select the checkboxes next to Access tokens and ID tokens to enable OAuth2 implicit grant for the application

Step 4: Configure the sample to use your Azure Active Directory tenant

  1. Open the solution in Visual Studio 2013.
  2. Open the web.config file.
  3. Find the app key ida:Tenant and replace the value with your AAD tenant name.
  4. Find the app key ida:Audience and replace the value with the Application (client) ID from the Azure portal.
  5. Open the file App/Scripts/App.js and locate the line adalAuthenticationServiceProvider.init(.
  6. Replace the value of tenant with your AAD tenant name.
  7. Replace the value of clientId with the Application ID from the Azure portal.

Step 5: Run the sample

Clean the solution, rebuild the solution, and run it.

You can trigger the sign in experience by either clicking on the sign in link on the top right corner, or by clicking directly on the Todo List tab. Explore the sample by signing in, adding items to the To Do list, removing the user account, and starting again. Notice that you can close and reopen the browser without losing your session. ADAL JS saves tokens in localStorage and keeps them there until you sign out.

About the Code

The key files containing authentication logic are the following:

App.js - injects the ADAL module dependency, provides the app configuration values used by ADAL for driving protocol interactions with AAD and indicates whihc routes should not be accessed without previous authentication.

index.html - contains a reference to adal.js

HomeController.js- shows how to take advantage of the login() and logOut() methods in ADAL.

UserDataController.js - shows how to extract user information from the cached id_token.
