Thank you for you feedback. Currently we are in public preview of Azure Active Directory authentication for storage. This feature set allows you to use Azure’s role-based access control framework to grant specific permissions to users, groups and applications down to the scope of an individual blob container or queue. You can see the public preview announcement here: https://azure.microsoft.com/en-us/blog/announcing-the-preview-of-aad-authentication-for-storage/
For any further questions, or to discuss your specific scenario, send us an email at firstname.lastname@example.org.
We can look into this if it’s a popular request.
