I have no idea and no experience at all with that.  Whatever happens,
there's nothing in Cygwin which knows anything about AD and its deep
mysteries, so any problems due to the SID history must be either
solved on a deeper level of the OS, or it must be solved by manual
intervention.  That's what I was trying to say.
