Comment 14 for bug 268663

This is still an issue in Karmic.

I tried using the 'inherit owner = yes' parameter both in /var/lib/samba/usershares/<sharename> and in /etc/samba/smb.conf, but this resulted in other clients not being able to write to the server, so it is not a fix

The only fix I have found is to set 'create mask = 0777' and 'directory mask = 0777' in the [global] section of /etc/samba/smb.conf which means the owner and group is still nobody:nobody, but full read/write permissions are granted to any user including guests on any file or directory created in the share.

Setting these two parameters in /var/lib/samba/usershares/<sharename> does not currently seem to work.
