OV2500 UPAM Radius to 3rd Party Wireless (Cisco)

Hi, saw the document for 3rd Party Cisco Switches for UPAM Radius 802.1x just wondering if the same approach can be done with Cisco 9800 WLC?

It will work for sure from my knowledge as Cisco Switch or Cisco WLC are authenticators and communicating to UPAM using Radius protocol.
