I have a network appliance filer running Ontap 7.3. I have a UNIX volume/Q-tree with 3.9 TB of allocated storage. I have NFS and CIFS shares pointing to the same volume. The NFS share permissions work fine. On the NFS side I am also able to limit access to certain IP addresses. On the CIFS shares, no matter what permission (ACL) I set, the shares are still open to everyone in the security domain. How do control volume access through the CIFS shares?
