Scenario: Setting up Single Sign-On (SSO) and determining license compliance for external users and guest accounts accessing an Azure enterprise application.

Solution 1Recommended

Verify External Identities and Licensing Requirements in Azure

Determine your licensing needs by identifying the authentication setup and consulting Microsoft Entra ID (formerly Azure AD) official licensing models for external users.

Licensing for external users accessing Azure enterprise applications depends heavily on how the users are authenticated and the specific Microsoft services involved. Azure typically uses a Monthly Active Users (MAU) billing model for External Identities, but this must be verified against your specific configuration.

Identify the Identity Type

Determine whether the users from the external organization will be configured as B2B guest users or external identities within your Azure Active Directory tenant.

Review Authentication Configurations

Check your enterprise application settings in the Azure portal to confirm the SSO method (e.g., SAML, OAuth, or OIDC) and note the specific Azure services being accessed.

Consult Azure External Identities Pricing

Visit the official Microsoft Azure pricing documentation for External Identities. Check if the Monthly Active Users (MAU) billing model covers your required volume of guest users without requiring individual premium licenses.

Seek Confirmation from Microsoft Q&A

Navigate to the Microsoft Q&A platform, select the Azure or Azure Community tags, and post your specific application and authentication setup to get authoritative confirmation from an Azure specialist.

Frequently Asked Questions

Do guest users need a paid license for Azure AD SSO?

Azure AD (Microsoft Entra ID) often utilizes a Monthly Active Users (MAU) billing model for External Identities. This typically allows a certain number of guest users to authenticate for free before incurring charges. Always check the latest Azure pricing documentation for exact thresholds.

What is the difference between an external identity and a standard user in Azure?

A standard user is typically an internal member of your organization with a directly assigned Microsoft 365 or Azure license. An external identity (or guest user) belongs to an outside organization but is granted access to your resources, usually falling under B2B collaboration licensing models.

How do I configure SSO for an external enterprise application in Azure?

You can configure SSO in the Azure portal by navigating to 'Enterprise applications'. Select your specific application, click on 'Single sign-on' in the left menu, and choose the appropriate method (such as SAML or Linked) based on what the application supports.
