Please take time to read the documentation provided by Microsoft on the Customer Technology Preview and also stay tuned for updates that will be coming out no doubt in the next few months around this product.

The release notes is documenting known issues with the customer technology preview (CTP) of Active Directory Sync Services. It can be particularly helpful for customers who are used to FIM2010.

Customer Technology Preview (CTP)

AADSync is available as a customer technology preview. It has all intended features and can be used to understand and validate the scenarios described in the scenarios overview. It does not represent the final product when it comes to quality, use in a production environment, and performance.

With the CTP we are looking for feedback regarding:

  • Is the configuration created by the installation guide suitable for most deployments?
  • Can your advanced scenarios be solved with the provided functionality?
  • Is it (reasonable) easy to understand the concepts?
  • Are there terms used which are confusing?

Please provide the feedback though the program on

It is not going to be supported to upgrade the CTP to later releases.

I am very excited about this latest update and from what I can hear in the community this is going to be great for those of you with more complex deployments that are looking to adopt Microsoft's Cloud Services!

Please feedback via the programme on your experience!
