Tutorial: Azure Active Directory integration with Heroku
In this tutorial, you'll learn how to integrate Heroku with Azure Active Directory (Azure AD). When you integrate Heroku with Azure AD, you can:
- Control in Azure AD who has access to Heroku.
- Enable your users to be automatically signed-in to Heroku with their Azure AD accounts.
- Manage your accounts in one central location - the Azure portal.
To get started, you need the following items:
- An Azure AD subscription. If you don't have a subscription, you can get a free account.
- Heroku single sign-on (SSO) enabled subscription.
In this tutorial, you configure and test Azure AD single sign-on in a test environment.
- Heroku supports SP initiated SSO.
- Heroku supports Just In Time user provisioning.
Add Heroku from the gallery
To configure the integration of Heroku into Azure AD, you need to add Heroku from the gallery to your list of managed SaaS apps.
- Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
- On the left navigation pane, select the Azure Active Directory service.
- Navigate to Enterprise Applications and then select All Applications.
- To add new application, select New application.
- In the Add from the gallery section, type Heroku in the search box.
- Select Heroku from results panel and then add the app. Wait a few seconds while the app is added to your tenant.
Alternatively, you can also use the Enterprise App Configuration Wizard. In this wizard, you can add an application to your tenant, add users/groups to the app, assign roles, as well as walk through the SSO configuration as well. Learn more about Microsoft 365 wizards.
Configure and test Azure AD SSO for Heroku
Configure and test Azure AD SSO with Heroku using a test user called B.Simon. For SSO to work, you need to establish a link relationship between an Azure AD user and the related user in Heroku.
To configure and test Azure AD SSO with Heroku, perform the following steps:
- Configure Azure AD SSO - to enable your users to use this feature.
- Configure Heroku SSO - to configure the single sign-on settings on application side.
- Create Heroku test user - to have a counterpart of B.Simon in Heroku that is linked to the Azure AD representation of user.
- Test SSO - to verify whether the configuration works.
Configure Azure AD SSO
Follow these steps to enable Azure AD SSO in the Azure portal.
In the Azure portal, on the Heroku application integration page, find the Manage section and select single sign-on.
On the Select a single sign-on method page, select SAML.
On the Set up single sign-on with SAML page, click the pencil icon for Basic SAML Configuration to edit the settings.
On the Basic SAML Configuration section, perform the following steps:
a. In the Sign on URL text box, type a URL using the following pattern:
b. In the Identifier (Entity ID) text box, type a URL using the following pattern:
These values are not real. Update these values with the actual Sign-On URL and Identifier. You get these values from Heroku team, which is described in later sections of this article.
On the Set up Single Sign-On with SAML page, in the SAML Signing Certificate section, click Download to download the Federation Metadata XML from the given options as per your requirement and save it on your computer.
On the Set up Heroku section, copy the appropriate URL(s) as per your requirement.
Create an Azure AD test user
In this section, you'll create a test user in the Azure portal called B.Simon.
- From the left pane in the Azure portal, select Azure Active Directory, select Users, and then select All users.
- Select New user at the top of the screen.
- In the User properties, follow these steps:
- In the Name field, enter
- In the User name field, enter the firstname.lastname@example.org. For example,
- Select the Show password check box, and then write down the value that's displayed in the Password box.
- Click Create.
- In the Name field, enter
Assign the Azure AD test user
In this section, you'll enable B.Simon to use Azure single sign-on by granting access to Heroku.
- In the Azure portal, select Enterprise Applications, and then select All applications.
- In the applications list, select Heroku.
- In the app's overview page, find the Manage section and select Users and groups.
- Select Add user, then select Users and groups in the Add Assignment dialog.
- In the Users and groups dialog, select B.Simon from the Users list, then click the Select button at the bottom of the screen.
- If you are expecting a role to be assigned to the users, you can select it from the Select a role dropdown. If no role has been set up for this app, you see "Default Access" role selected.
- In the Add Assignment dialog, click the Assign button.
Configure Heroku SSO
In a different web browser window, sign-on to your Heroku tenant as an administrator.
Click the Settings tab.
On the Single Sign On Page, click Upload Metadata.
Upload the metadata file, which you have downloaded from the Azure portal.
When the setup is successful, administrators see a confirmation dialog and the URL of the SSO Login for end users is displayed.
Copy the Heroku Login URL and Heroku Entity ID values and go back to Basic SAML Configuration section in Azure portal and paste these values into the Sign-On Url and Identifier (Entity ID) textboxes respectively.
Create Heroku test user
In this section, a user called B.Simon is created in Heroku. Heroku supports just-in-time user provisioning, which is enabled by default. There's no action item for you in this section. If a user doesn't already exist in Heroku, a new one is created after authentication.
In this section, you test your Azure AD single sign-on configuration with following options.
Click on Test this application in Azure portal. This will redirect to Heroku Sign-on URL where you can initiate the login flow.
Go to Heroku Sign-on URL directly and initiate the login flow from there.
You can use Microsoft My Apps. When you click the Heroku tile in the My Apps, this will redirect to Heroku Sign-on URL. For more information about the My Apps, see Introduction to the My Apps.
Once you configure Heroku you can enforce session control, which protects exfiltration and infiltration of your organization’s sensitive data in real time. Session control extends from Conditional Access. Learn how to enforce session control with Microsoft Defender for Cloud Apps.
