We have shipped a public preview of integration with AAD DS: https://azure.microsoft.com/blog/azure-active-directory-integration-for-smb-access-now-in-public-preview/
What we have in preview is a first step along a much larger roadmap for integration with AAD/AD for authentication and authorization. As the blog post says, this initial preview is really about Windows cloud VM access to the Azure file share with an AAD identity. Future refreshes to this feature will add non-Windows (Linux, macOS, etc) support, and the ability to mount the Azure file shares on-premises with your AAD identity. You can learn more about this in our Ignite session as well (at around 22:00): https://www.youtube.com/watch?v=GMzh2M66E9o
We’ll keep you updated on our progress. In the meantime, don’t hesitate to continue posting feedback on this feature below.

This will be a great feature once AD integration and ACLs are added. Until then... it's basically useless.
Thanks for the feedback.
