On Mac and Windows you would not get SSO anyways because Kerberos on 
thos platforms does not support latest RFCs related to 2FA at least yet 
and since they are proprietary it is unclear what their plans are.

The problem we also have is that there is no way to be selective on the 
KDC/DS side - there is no way to determine what the client is and 
associate some policies to it.
It would have to be the client that would have to have capability to 
enforce or not enforce 2FA if the server supports both. But again that 
means that Mac and Windows would have to keep up with this capability.

Bottom line it is a popular request but it is unclear how we can satisfy it.
