I have a new Mac Mini running Yosemite with Server app. Short story is I have a shared folder on an external (TB) drive array. Let's call it "Shared". Underneath "shared" are thousands of folders/subfolders/files. It the main share for a dept. at work. We have two groups that have been assigned permissions. A Read/Write group and a Read Only group (RW and RO). I have assigned, at the "Shared" folder, both groups with the respective permissions (either read/write or read only) and chose to "apply to enclosed items" so the permissions would flow down into all the files and folders under "Shared". Everything looks great, I can check any subfolder under "Shared" and they have the correct permissions. HOWEVER, when someone in the RW group saves a new file into a folder, the file does not inherit the permissions of the folder! In other words, if FILE.JPG is saved into a folder with the correct permissions, the file permissions for the new file only have RW group. No RO group permission is given to that file. Hence someone in the RO group cannot access (open) or even copy the file. Access denied! It's driving me crazy why permissions are so wacky here. It's frustrating for the employees as well. Any help or advice as to why saving a file into a folder, the file does not inherit the permissions of the parent folder? Thanks!
