Hi, thanks for the answer!
However I'm still having problems, maybe I should have mentioned in the OP that I'm running against a Samba 4 Domain aswell.
On the supplicant I ran: netsh ras set tracing * enabled. Everything seems to be fine until the end of the log when I recieve the following error:
[13660] 07-09 12:25:38:425: Success received...
[13660] 07-09 12:25:38:426: Done :)

[7996] 07-09 12:25:38:542: EapMSChapv2End
[7996] 07-09 12:25:38:542: ChapEnd
I've googled my heart out on this problem but have yet to find anything usefull, maybe Samba is just not supported by the controller?
Thanks again for the help!
