Secure a Web App Using Azure AD
Enable SSO and Granular Access Control For A Header-Based Web App with Microsoft Azure Active Directory (AD)
In this tutorial, we will use the Datawiza Access Proxy (DAP) to enable SSO and granular access control for a header-based web App. The IdP we will use is Azure AD. We will use DAP's sidecar deployment mode, which means DAP and this app are running on the same server.
- The application will run on
- The DAP will run on
localhost:9772, which means the traffic to the app will reach DAP (running on port 9772) first and then be proxied to the application (running on port 3001).
- We will provide the docker images for the DAP and this header-based application.
Part I: Azure AD Configuration
You will need to register an OIDC application in Azure AD management portal and get the following 3 values for this application:
- Tenant ID
- Application (client) ID
- Client Secret
These values will later be used to set up Datawiza Access Proxy in Datawiza Cloud Management Console. Please follow IdP Configuration Guide: Microsoft Azure AD instructions on how to get those keys/values.
Part II: Create Application on Datawiza Cloud Management Console (DCMC)
You need to create an application and generate a keypair of (
PROVISIONING_SECRET) for this app on the DCMC.
Please follow Step2 : Datawiza Cloud Management Console to configure.
For Azure AD, you can use the One-Click function we provided to generate the Azure AD app automatically: Also, if you already have an Azure AD app, you can use it by disable the
Automatic Generator option and populate the fields of the form with the keys/values.
Part III: Run DAP With a Header-Based Application
You can use either Docker or Kubernetes to run DAP. The following is an example
docker-compose.yml file. You may need to login to our container registry to download the images of DAP and the header-based app. See Step3 : Configure DAP and SSO Integration for more details or Deploy DAP with Kubernetes for Kubernetes-specific instructions.
version: '3' services: datawiza-access-broker: image: registry.gitlab.com/datawiza/access-broker container_name: datawiza-access-broker restart: always ports: - "9772:9772" environment: PROVISIONING_KEY: ############################# PROVISIONING_SECRET: ############################# header-based-app: image: registry.gitlab.com/datawiza/header-based-app container_name: ab-demo-header-app restart: always ports: - "3001:3001"
docker-compose -f docker-compose.yml up, the header-based app should have SSO enabled with Azure AD. Open a browser and type in
http://localhost:9772/. You should see the Azure AD login page as follows. If you are seeing the Azure AD login page but are unable to login (Microsoft keeps asking for your username and password repeatedly), ensure that you have created a user for your AD domain. Logging in with the root account will not work. Your username should be in the form of
user@your_domain.onmicrosoft.com. Note that if you are already logged into Azure AD in your browser, you may need to logout to see the login page.
Part IV: Pass User Attributes to the Header-Based App
DAP gets user attributes from IdP and can pass the user attributes to the application via header or cookie.
Please follow the instructions of Step4 : Pass User Attributes to pass the user attributes to the header-based app, which is expecting:
After successfully configuring the user attributes, you should see the green check sign for each of the user attributes as follows.
Part V: Achieve Granular Access Control
You can configure access control to an application based on user's attributes (e.g., groups, department) and other metadata of a request (e.g., URL, IP, http method, access time).
Please reference Step5 : Achieve Granular Access Control for detailed instructions on how to set up access rules. You can practice the rule configuration using the following example.
A Rule Example
Create a user in Azure AD, put it in
hrgroup, and then assign this person to your application on Azure AD.
Create the following two rules:
hr pathcan only be accessed by
sales pathcan only be accessed by
- Verify that the user you created can only access
hrpage in the header-based app, but cannot access
salespage. Trying to access the header-based application on
localhost:9772in your browser, you should get something similar to the following screenshots.
