[Samba] smb.conf

[Gerald]

Hi guys

My client is really bugging me to get this working.
I create a folder called "private" and added this into my smb.conf file, 
but when i browse to the folder "private" using wendy or pierre i  get 
access denied.  soneone told me i must make sure the filesystem of the 
folder private is set to nobody. Is that correct and how will i go on by 
doing this.

[private]
  writeable = yes
  public = no
  guest ok = no
  path = /home/samba/private
  valid users = pierre, wendy
  write list = pierre, wendy
  force user = nobody

Regards
Gerald
