[Announcement] Connectivity issues from synchronized users to VMs joined to AAD DS

ArthurOpenhost : I wouldn't say that no one is using Azure AD DS or that it's not a viable solution. Primarily, understanding this failing scenario is an intersection of where customers are today and how they are piloting Windows Virtual Desktop with just cloud users (before trying to extend this with a full site-to-site on-prem infrastructure).

Between using Azure AD DS or extending existing domain structure to Azure, it depends on your scenarios you're targeting. You have much more flexibility by extending, since you can use Federation, Passthrough Authentication, or password hash (whereas AAD DS only works with password hash). Not sure if you've already seen this comparison article.
