Linux SME Server FTP

I have an older Linux SME Server (8.1) that was setup to be utilized for our FTP server so our clients can upload information. We have moved this server over to a different VM as the old VM machine was failing. At this point this particular VM has started to fail as well, and won't do backups. I've created a 9.0 VM to try and rebuild the server. I've got everything up, but when I create the groups, and then add users (which creates subfolders within that group) and then I try to FTP with that user, it will pull up just fine, but I cannot add files, I can pull them off just fine, just says permission denied. I cannot find anywhere to change these permissions. I've read into i-bays but that particular route isn't exactly what I need to work, unless I am doing it wrong.  At this point I just need to get something working, and then work from there. I also need to be able to create an smb share so I can map the drive where the ftpclients and ftpvendors are so our company can access the information easier.
