[Samba] Adding a windows user to unix group?

[Paul Postin]

Hi All,
 
Running version 3.0.14a on freebsd 5.4. configured as a member server of a
2k domain. the directory i need access to is for public websites
/usr/local/www/sites and permissions are drwxr-xr-x  www  www. A single
share is configured as below:
 
# FTP share
[ftp_share]
   comment = FTP Share
   path = /usr/local/www/sites
   valid users = domain\user
   browseable = no
   read only = no
   writable = yes
   printable = no
   public = no
   write list = domain\user
 
This share is to allow ftp access from a central ftp server which serves
several webservers (all windows until now) via a mysql database and UNC
paths.
 
I can access the folder but have no permissions in it. I believe i need to
add the windows user account the the unix www group but have no idea how to
do it. This is my first experience of samba and all went really well...this
is the last thing to sort!
