Okay, out of event viewer this is what I get when I try to login from site 2 on a windows machine:
User bnewton was denied access.
Fully-Qualified-User-Name = usd260.local/ESC/ESC/CSD/BNewton
NAS-IP-Address = 192.168.0.6
NAS-Identifier = Dot1X-HS
Called-Station-Identifier = 000B86143C80
Calling-Station-Identifier = 00215C7DF81F
Client-Friendly-Name = DHS-Wifi
Client-IP-Address = 172.18.128.241
NAS-Port-Type = Wireless - IEEE 802.11
NAS-Port = 0
When I setup a log file here is what I get:
