I have a server we use to host samba shares, and quite regularly we're seeing files/folders with incorrect permissions, they're getting drwxr-xr-x instead of drwxrwxrw-.

In our smb.conf, we have force user and force group set, and those are correct even on the problem folders. But we also set these two settings in smb.conf:
create mask = 0764
directory mask = 0776

I have a hunch that the machines added the folders with the incorrect permissions are OSX machines, so not sure if since that is based on Unix it's doing something funky with samba?

Any ideas what to check or what other settings to configure in smb.conf to prevent this from happening?

I believe that is happening due to the default umask set value which is 0755

The share which you have configured in smb.conf, is that accessible by public or a list of valid users?

The share is accessible via public/guest, as we do a force user and force group for this share in particular. What is a umask?

Thanks. I never even heard of that before. Any thought as to why OSX machines would use this rather than what's in smb.conf while when PCs connect to the share they get those forced masks from the samba config?
