OT: Windows 8 beta supplicant always prefixes computer name to user name

[Martin Pauly]

Hi all,

sorry, this is much OT. As many, we do PEAP with the help of ntlm_auth,
both wired and wireless. Today, my first Windows 8 user walked in, 
wanting to do wired 802.1X. Setting things exactly as in Windows 7 
results in the computer name always showing up as (pseudo-)domain 
in the authentication dialog. It's visible, but not changable. 
Subsequently, what I see in the server is (real names replaced):

rad_recv: Access-Request packet from host 192.168.4.249 port 1645, id=98, length=161
        User-Name = "PCNAME\\username"
        Service-Type = Framed-User
        Framed-MTU = 1500
        Called-Station-Id = "00-11-BB-A7-94-8D"
        Calling-Station-Id = "F0-BF-97-D1-97-53"
        EAP-Message = 0x02010011014d455048495c426162616569
        Message-Authenticator = 0x882ea6dd7bcb0c978b71d1da77ce7753
        NAS-Port-Type = Ethernet
        NAS-Port = 50211
        NAS-Port-Id = "FastEthernet2/0/11"
        NAS-IP-Address = 192.168.4.249

username is not Windows' local username, cf. last part of
