Set up Microsoft Azure AD in the Azure Portal

• Visit the Azure Portal and sign in with your Azure account. You need to have an active subscription to access Microsoft Azure AD.
• Click the Azure Active Directory from the services they offer, and click the App Registrations from the left menu.
• Click New Registration at the top, enter a description, select your access type and add your Redirect URI, which will redirect the user to the application after logging in. In our case, this will be ${your_logto_endpoint}/callback/${connector_id}. e.g. https://foo.logto.app/callback/${connector_id}. (The connector_id can be also found on the top bar of the Logto Admin Console connector details page)

  You can copy the Callback URI in the configuration section.

• Select Web as Platform.

Fill in the configuration in Logto

| Name | Type | | ------------- | -------- | | clientId | string | | clientSecret | string | | tenantId | string | | cloudInstance | string | | prompts | string[] |

Client ID

You may find the Application (client) ID in the Overview section of your newly created application in the Azure Portal.

Client Secret

• In your newly created application, click the Certificates & Secrets to get a client secret, and click the New client secret from the top.
• Enter a description and an expiration.
• This will only show your client secret once. Fill the value to the Logto connector configuration and save it to a secure location.

Cloud Instance

Usually, it is https://login.microsoftonline.com/. See Azure AD authentication endpoints for more information.

Tenant ID

Logto will use this field to construct the authorization endpoints. This value is dependent on the access type you selected when creating the application in the Azure Portal.

• If you select Accounts in this organizational directory only for access type then you need to enter your {TenantID}. You can find the tenant ID in the Overview section of your Azure Active Directory.
• If you select Accounts in any organizational directory for access type then you need to enter organizations.
• If you select Accounts in any organizational directory or personal Microsoft accounts for access type then you need to enter common.
• If you select Personal Microsoft accounts only for access type then you need to enter consumers.

Prompts

The prompts field is an array of strings that specifies the type of user interaction that is required. The string can be one of the following values:

• prompt=login forces the user to enter their credentials on that request, negating single-sign on.
• prompt=none is the opposite. It ensures that the user isn't presented with any interactive prompt. If the request can't be completed silently by using single-sign on, the Microsoft identity platform returns an interaction_required error.
• prompt=consent triggers the OAuth consent dialog after the user signs in, asking the user to grant permissions to the app.
• prompt=select_account interrupts single sign-on providing account selection experience listing all the accounts either in session or any remembered account or an option to choose to use a different account altogether.

Logto will concatenate the prompts with a space as the value of prompt in the authorization URL.
