Jonathan's images have checkbox in the RADIUS portion of the Captive 
Portal config labeled "Enable for cisco."

"If RADIUS type is set to Cisco, in Access-Requests the value of 
Calling-Station-Id = Clientip and Called-Station-Id = Clientmac. Default 
behavior is Calling-Station-Id = Clientmac without sending a 
Called-Station-Id value."

Currently to make both values the client's MAC, you're going to have to 
edit Jonathan's source.

Calling-station-id should be client's mac by default though. Do you have 
  "Enable for cisco" checked or not? What RADIUS server are you using?

You should be able to set the RADIUS debugging to log the RADIUS packets 
and see if it is receiving a calling-station-id value and if it is correct.
