[Samba] [3.0.28,1/smb.conf] Can't hide dot files

[Gilles]

Hello

	I set up Samba 3.0.28,1 on a FreeBSD 6.3 host. I'd like users _not_
to see the hidden dot files in directories, but "hide dot files"
doesn't work, no matter whether I put it in [global] or [homes]:

======
[global]
workgroup = WORKGROUP
netbios name = Samba
hosts allow = 192.168.0. 127.
log file = /var/log/samba/log.%m
max log size = 50
socket options = SO_RCVBUF=8192 SO_SNDBUF=8192
hide dot files = yes

[homes]
comment = Home Directories
valid users = %S
read only = No
browseable = No
hide dot files = yes
======

Any idea why?

Thank you.
