Note: To back up a Mac via TimeMachine/AFP, the share must be private.

Add User to Share

This feature is used to add user(s) to the share. The list displays all device users, minus the users that are already assigned to the share.

Check the box Add as admin to enable administrative rights for the user.

  • Enable FTP, AFP/Time Machine, NFS: Enable the protocols that you want to use to access this share.

iSCSI Share Settings

The only Access Control List setting for iSCSI shares is CHAP Authentication.

CHAP provides two levels of security:

  • One-way CHAP authentication: Only the remote client (the initiator) needs to provide a password to start a logon session with the share (the target).
  • Mutual CHAP authentication: Requires that both the client (the initiator) and the share (the target) authenticate each other.
