Hasn't this been implemented in 8.2.1?
Cannot find a doc right now, but I think I've read it somewhere
Edit:
found it in the release notes of 8.2.1 p53:
Starting with Data ONTAP 8.2.1, you can create and manage Active Directory (AD) computer
accounts for Storage Virtual Machines (SVMs) even if you do not have CIFS licensed on any of the
cluster nodes.
