Microsoft Azure Access Control Service will be retired November 7, 2018. Learn about options for migrating.

Microsoft Azure Active Directory Access Control Service (ACS), a cloud authentication and authorization service, will be retired on November 7, 2018. Any applications or services currently using ACS will need to migrate to a different authentication service before this date. On November 7, 2018, the services will cease to work and all requests will fail.

Microsoft ACS customers should take efforts now to migrate off of ACS, as this process will likely require significant code changes. You can read Microsoft’s ACS retirement announcement here. The ACS retirement affects any Microsoft Azure customer with ACS namespaces in their subscriptions.

Use Cases

Use Cases

ACS currently supports the following authentication scenarios. Each of these use cases requires migration:

Get tokens for Microsoft first party services, such as Azure Service Bus, Azure Relay, BizTalk, and more. In this use case, users authenticate with ACS to acquire tokens that authorize access to other Microsoft services on a first-party basis. To migrate in this scenario, customers should follow guidance provided by the service and/or move to a newer Microsoft cloud service.

Federated sign-in for web apps, such as custom websites, Sharepoint, generic Ws-Fed IdPs including AD, ADFS, and more. In this use case, users can use the same identity to log into multiple applications or services. To migrate this scenario, a different solution must be implemented; you can move to AAD, B2C, build your own proprietary system, or migrate to a powerful and robust platform such as Auth0.

Get tokens for custom-built third party web services, such as delegation of custom tokens, server-to-server, and more. In this use case, users authenticate with ACS to acquire tokens that authorize access to custom-built third party web services. To migrate this scenario, a different solution must be implemented; you can move to AAD, build your own proprietary system, or migrate to a powerful and robust platform such as Auth0.
