This from my previous post.  This only applies to the MS supplicant.  RD works with a 3rd party supplicant.
I hardcoded Machine Auth ONLY to ensure not breaking RD until fixed. 
From MS FAQ: 
Q.Do Remote Desktop connections work to Windows wireless clients that use 802.1X authentication? 
A.Not at this time. All 802.1X-based wireless connections are affected, including those using EAP-TLS or PEAP-MS-CHAP v2. Connections using a static WEP key or WPA-PSK are not affected. Microsoft is investigating this issue.
