I've never used AzureAD for this ... but it is completely cloud based and looks like it is a bit easier to me, especially since they provide a direct LDAP interface.
If you use Office 365 for email and documents then this would bind everything together for you.
The last time I tried to implement this, I needed a local AD. Which is redundant for organisations which have bought into Cloud-based services and infrastructure. However, it is entirely feasible to run RADIUS on the gateway device (MX).
I remain confident that AzureAD will handle remote authorisation in a useful manner.
