I am not sure, I am using certificate machine autorollment. Don't know 
where to set the keys on the cert to be exportable.

However, this is not critical now. I think I can use PEAP instead of TLS 
to authenticate wpa_supplicant if I can not use the client certificate. 
Am I right? However, the question now becomes how do I find out the 
password of the machine account that get created when an client machine 
join a domain. So that I can use this password to put on to 
wpa_supplicant's configuration to see if that would work.

Bryan, you mention "You could install a password-change-sniffer DLL on 
the DC and get the password from it" , would you mind giving more  
details on this?
