ACL and freebsd

[Jeroen Molinger]

I have a samba 3.0.7 pDC with fbsd 5.3 witch runs fine. I just can't get 
the acl function to work.
when I use properties->securirty of a file or directory I get a acces 
denied when changing the ACL. Or the change just disapears????
Has anyone a clue

here is the smb.conf:
