Thanks for your answer but i think I did't described the problem precisly enough.
The problem I have is, that I need different access-rules inside one single ibay.
For example there are users A, B, C and D.
Folder 1 = for all read and write.
Folder 2 = read for A, read+write for D
Folder 3 = read for A,B,C read+write for D
Folder 4 = read for all, writable for C
Any Idea how i could make this possible without creating lot's if ibays?
If under MS Server 2003 I could just right-click and set access-rights. But how can I handle this with SME (or Samba in general)?
