I absolutely agree with almost everything that has been said in this thread. Having RADIUS and LDAP for authentication and directory services would be huge for usability and cloud only environment. There are many RADIUS aas, Directory aas, etc out there, add the functionality and bundle, make a profit. Most of us would be happy to pay more for something that is hosted and mostly managed by microsoft when all of us are already using AAD for identity.
