IMMEDIATE ACTION: Microsoft to retire ACS (Access Control Services) for 2012 customers – Whitelist deadline May 1, 2018

By Sarah D. Morgan, Customer Success Manager

This is time sensitive announcement for Microsoft Dynamics AX and CRM users. Microsoft is retiring Access Control Services used in AX 2012 to configure the Azure Service bus, AD Federation Services and enable Workflow approval by email feature.

Microsoft announcements include: “Microsoft does have a future roadmap that will migrate ACS to SAS. Application updates will be released before the support of ACS is depreciated. Until then, Azure support will continue to support new AX 2012 customers with their whitelisting process. The whitelisting process will end May 1st, 2018.

Until November 7, 2018, all other ACS functionality will continue to work. This includes the ACS secure token service, the ACS management service, and the ACS token transformation engine. After this date, all ACS service and functionality will be shut down. By this time, users should ensure that all traffic has been migrated off Access Control Service to other technology.”

What you need to do now:

All customers who use this functionality need to be whitelisted by May 1, 2018 and plan on getting migrated to SAS by November 7th, 2018. 

A typical use case involving ACS was ‘Workflow Approval by Email’. If you have this setup, you need to take immediate action. More information can be found here:

How Arbela can help:  

For many customers, it will take time to assess the change, to analyze if the change is necessary, and what to do to be in compliance again. Arbela can assess your environment, create an action plan for getting customers whitelisted and ready for the November 7 upgrade. This is an approximate 16-hour engagement performed by a senior technical Arbela architect.

If you miss the deadline:

If you miss the deadline, services that will be dysfunctional are:

  1. Workflow approval via email
  2. Expense App

Below is an example of the support ticket you will create to alert Microsoft:

Ticket Description

Hello there,

We have an Azure service bus with type “ACS Namespace” and it is the only way the Microsoft Dynamics AX 2012 Workflow via Email functionality work.

Microsoft does have future roadmap; that will migrate ACS to SAS but for now, we do not have another option where we can make the SAS Service bus work.

Please whitelist my subscription, so it doesn't get decommissioned after May 1st, 2018.
