Description (partial)

When using AP group interface on "RADIUS Server Overwrite interface" WLC uses global WLAN interface IP address in NAS-IP attribute instead of the AP group interface for radius authentication requests.
It uses the AP group interface as source for radius traffic as expected but the problem is that it doesn't update the NAS-IP attribute in radius requests to the correct AP group interface.

WLAN with "RADIUS Server Overwrite interface" enabled to AP Group priority.
This was seen for auth request messages, accounting messages are sent with the correct NAS-IP.
