I have set up an Ubuntu server (12.04 LTS) for samba file sharing. The problem I'm having has to do with files that I create on the server. Other users can't open them because I created them under a group that is my username, instead of the group that is allowed to view the share. Why is this? It seems that everything else is working fine. Only allowed users are able to view their share folders but they can't open anything that I create.
