So, quite apart from the fact that a Samba member server would not
know that group membership has changed, and that you would have to get
Samba to change, for each affected currently logged on session, the
set of SIDs that are appropriate (deleting some and adding some in the
general case), this is not how Windows works, I believe.

A better approach might be to implement he new dynamic (claims-based
SIDs) in Samba.
