I did some tests and came to the same conclusions (that is, I need to copy
and  not  move files). I did not know that WinNT does the same, I supposed
it should have worked correctly.

I  really  don't have an elegant way of avoding this issue, because I also
have all directories with different ACLs on a single big file system.

Maybe  this issue should be discussed on the ACL list instead of the Samba
one.  A possible (horrible) workarond from a Samba perspective could be to
remap  "move"  operations  to  "copy  and  delete"  ones. Another (better)
workaround  involves  smbd  applying  default  ACLS to files when they are
moved  to  the destination directory. But again I suppose this is an issue
with file system ACL support, and not with Samba.
