[Samba] users can't change permissions on samba share

[Justin Georgeson]

I have 2.2.5 (installed using binary RPM) on Red Hat 7.2 (should be 
fully up2date). This server is acting as a PDC, and is working fine for 
the most part. The problem I'm having is that nobody can change 
permissions for files and folders on a service. I've attached my 
smb.conf. I believe everyone change edit permissions for files/folders 
in their profile. But nothing in the Public share can be changed. New 
files/folders can be created/deleted. But they are created with the 
wrong permissions and the permissions can't be changed. Please help.
