Yes indeed, Samba adjusts the Linux acls to match the Windows ACLs (as 
well as Linux acls can).

Not sure which email you mean. I don't think that this can happen. If 
the Linux acls are modified, the Windows ACLs are destroyed and all is 
based on the Linux permissions and acls (which looks strange when viewed 
from Window). If the Windows ACLs are modified, Samba automatically 
adjusts the Linux acls accordingly. They should always be in sync.
