MAC Address based Wireless Authentication (802.1x)

My Security Team wants us to setup our ThinOS devices to authenticate to wireless Per Device as separate users.  I figured I'd just use the $Mac.ini and it would work...  (These are Wireless Medical Carts)

There seem to be a couple of issues.

1) One issue is how exactly to setup the two .ini files.  If I have no wireless in the WNOS.ini file, it fails to connect upon reboot.  If I have a GenericUser in WNOS.ini, and the SpecificUser setup in the MAC.ini file, it sees a wireless change and gets caught in a reboot loop.    If I just have the User/Password variables (see below) it seems to ignore it since it has already authenticated to wireless to get the files!!

2) Another issue is that the 'MirrorFileServer=yes' command only seems to cache the WNOS.ini file (and wireless setting) So upon reboot, it fails... Can I cache the MAC.ini file?

I'd appreciate it if you could help me find a solution.  Is everyone here just using a single login for wireless on all ThinOS wireless devices?

WNOS.ini

MirrorFileServer=yes
