ProFTP Group Permission problem

Hi, I want files that are uploaded to have a different Group id from the User Id. Assuming that the normal ftp user is 'admin', using the stock settings a file uploaded to a directory would end up looing like: [code:1:c491dee2f4] -rw-r--r-- 1 admin admin 2343 Jul 15 10:37 test.mp3 [/code:1:c491dee2f4] Using Umask inside a <Directory> config, I can get the file to become [code:1:c491dee2f4] <Directory /var/www/html/media> Umask 0002 </Directory> result: -rw-rw-r-- 1 admin admin 2343 Jul 15 10:37 test.mp3 [/code:1:c491dee2f4] However, when I add the GroupOwner directive, nothing changes. In /etc/group, I've defined 'www3' as a new group: www3:x:605:admin3,apache and modifyed the above directive as follows: [code:1:c491dee2f4] <Directory /var/www/html/media> Umask 0000 GroupOwner www3 </Directory> [/code:1:c491dee2f4] But when I upload a file, it still shows up as: -rw-rw-r-- 1 admin admin 2343 Jul 15 10:37 test.mp3 instead of the desired: -rw-rw-r-- 1 admin www3 2343 Jul 15 10:37 test.mp3 Any thoughts? Am I using the right directive for Proftpd -- version 1.2.8 Other notes: These directives are encapulated in a <VirtualHost xx.xx.xx.xx> directive. (I've tried using the 'group' name from the 'virtual host' also, but no luck either.)
