Obtain a ClientId and Client Secret for Microsoft Azure Active Directory
This page uses the current portal of the Azure Active Directory, for information on using the classic portal, click here.
To allow users to login using a Microsoft Azure Active Directory account, you must register your application through the Microsoft Azure portal. If you don't have a Microsoft Azure account, you can signup for free. You can access the Azure management portal from your Microsoft service, or visit https://manage.windowsazure.com and sign in to Azure using the global administrator account that was used to create the Office 365 organization.
NOTE: There is no way to create an application that integrates with Microsoft Azure AD without having your own Microsoft Azure AD instance.
1. Create a new Microsoft Azure Active Directory instance
Login to Microsoft Azure and click on Active Directory on the Dashboard.
Then go to DIRECTORY -> CUSTOM CREATE
Enter a domain, e.g.: YOUR_TENANT. This can be any text, it does not have to match the Auth0 subdomain and it will be used in the next step. Also enter your country and a friendly name for your organization.
2. Create a new application
Click on App registrations under MANAGE, then click the Add button.
Enter a friendly name for the application, select WEB APPLICATION AND/OR WEB API, and for Sign-ON URL enter your application URL (completely arbitrary).
3. Configuring the permissions
Once the application has been created, you will have to configure the permissions. Click on the name of the application to open the Settings section, then click Required permissions.
Then click on Windows Azure Active Directory to change the access levels.
The next step is to modify permissions so your app can read the directory. Under DELEGATED PERMISSIONS check next to Sign in and read user profile and Read directory data.
NOTE: If you want to enable extended attributes (like Extended Profile or Security Groups) you will also need to enable the following permissions: Application Permissions: Read directory data, Delegated Permissions: Access the directory as the signed-in user.
Click the SAVE button at the top to save these changes.
4. Creating the key
Next you will need to create a key which will be used as the Client Secret in the Auth0 connection. Click on Keys from the Settings menu.
Enter a name for the key and for the duration of the key select 1 or 2 years.
Click on Save and the key will be displayed. Make sure to copy the value of this key before leaving this screen, this is your Client Secret used in the next step.
5. Copy the Client ID and Client Secret to Auth0
Login to your Auth0 Dashboard, and select the Connections > Enterprise menu option. Select Windows Azure AD.
For the Client ID, this value is stored as the Application ID in Azure AD.
For the Client Secret use the value that was shown for the key when you created it in the previous step.
Congratulations! You are now ready to accept Microsoft Azure AD users.
When granting access, make sure to use an Incognito/InPrivate window and a Global Administrator user.
If you get Access cannot be granted to this service because the service listing is not properly configured by the publisher, try enabling Multi Tenanted in the Windows Azure AD application under Settings -> Properties.
Signing Key Rollover in Azure Active Directory
Signing keys are used by the identity provider to sign the authentication token it issues, and by the consumer application (Auth0 in this case) to validate the authenticity of the generated token.
For security purposes, Azure AD’s signing key rolls on a periodic basis. If this happens, you do not need to take any action. Auth0 will use the new key automatically.
