M365 Changelog: Azure Active Directory Application Proxy header-based authentication (in preview)

MC228668 – Now in public preview, Azure Active Directory (AD) Application Proxy natively supports apps that use header-based authentication.

This message is associated with Microsoft 365 Roadmap ID 68895. 

When this will happen

The public preview is available now. We will communicate again before this feature becomes generally available.

How this will affect your organization

Customers can use their existing Application Proxy connectors with header-based authentication apps and no changes to their apps are needed. All header values available are based on standard claims that are issued by Azure AD. All attributes and transformations available for configuring claims for SAML or OIDC applications are also available to be used as header values.

What you need to do to prepare

To connect a header-based authentication application to Application Proxy, make sure you have Application Proxy enabled in your tenant and have at least one connector installed.
