You likely don't have ACL's enabled on the filesystem that samba is sharing. You can check with

sudo tune2fs -l /dev/vg_lillie/lv_root | grep option

replacing your disk into that command. You should see something like

Default mount options:    user_xattr acl

If not, you should enable the filesystem ACL using tune2fs, then reboot your machine.

tune2fs -o acl /dev/sda1
