I suspect that means that AD must use objectclass groupofNames ?
Yea I don't know what is needed to provide the desired functionality.

Hi, a guy called Stephane Purnelle has proposed a patch for samba-tool to do this, but I keep objecting to it because it also adds the posixGroup objectClass, windows never adds this, so I think that samba-tool shouldn't either, no one from the devs ever responds.
