[Samba] copy NT permissions

[Hamish]

Hello
I would like to move a large amount of data from various windows file 
servers onto a samba server. I have tried to be clever and use various 
backup tools etc for copying the files and they copy fine, but their 
acls, permissions and ownership are all destroyed in the copy process. 
(it seems to own the files from the user that connects to the share)
Has anyone had any success in copying ACLs and permissions from an NT share?
Thanks
Hamish
