MAC binding and address list?

Question

I have noticed that the user maintenance screen includes a MAC address list and an option to bind the MAC to the user. So, I was assuming that this would allow me to link devices the user is using to the user id. However, that doesn't seem to work. 
 Do I misunderstand this functionality? Could somebody please explain to me what it is for? 
 Thanks, 
 Jens

Jens, 
 you can bind IP and MAC addresses using DHCP options inside Network > DHCP TAB and DHCP Server Name. 
 If you are using Login restrictions, the situation is a little bit different. See the following details (from online help): 
 MAC Binding 
 Enable/disable MAC Binding . By binding the user to a MAC address, you are mapping the user with a group of MAC addresses. 
 If enabled, specify MAC addresses for example 01:23:45:67:89:AB. 
 Once you enable MAC binding, the user will only be able to login through pre-specified machines. 
 Use a comma to seperate multiple MAC addresses. For example 01:23:45:67:89:AB, 01:23:45:67:89:AC. 
 Login Restrictions 
 Select the appropriate option to specify the login restriction for the user. 
 Available options: 
 ▪ Any Node - User will be able to login from any of the nodes in the network. 
 ▪ User Group Node(s) - User will be able to login only from the nodes assigned to his group. 
 ▪ Selected Nodes (only available for IPv4) - User will be able to login from the specified nodes only. 
 ▪ Node Range (only available for IPv4) - User will be able to login from any of the IP addresses from the configured range.
