Added some new offices and have deployed a C5 stack with 4 wireless APs (3715's).
Using existing VNS configuration which still currently work at the main building, this new building can't connect to a specific SSID which is using 802.1x.
We have an IPsec tunnel between the two buildings.
Wireshark capture of the conversation at the RADIUS server shows RADIUS server is receiving the packets and sending them back out to the wireless controller.
