question about windows users

14 May 2009

      Hi,
I have freeradius with eap support on debian etch, radius v1.1.3
"everthing" working fine but I'd like to have much more simple configuration
only by certificate and nothing more,
so I have few question:

1.
fragment of my log first, before question
Listening on authentication *:1812
Listening on accounting *:1813
Ready to process requests.
rad_recv: Access-Request packet from host 192.168.5.206:1812, id=182,
length=159
        NAS-IP-Address = 192.168.5.206
        NAS-Port = 50046
        NAS-Port-Type = Ethernet
        User-Name = "PC-01\\Administrator"
        Called-Station-Id = "00-0C-30-81-9B-EE"
        Calling-Station-Id = "00-0A-E4-13-1A-02"
        Service-Type = Framed-User
        Framed-MTU = 1500
        EAP-Message =
0x0200001b014e4c504c2d4943455c41646d696e6973747261746f72
        Message-Authenticator = 0xe0b4e2966553f890137d9e56bebd0b3d
  Processing the authorize section of radiusd.conf
modcall: entering group authorize for request 0
  modcall[authorize]: module "preprocess" returns ok for request 0
  modcall[authorize]: module "mschap" returns noop for request 0
    rlm_realm: No '@' in User-Name = "PC-01\Administrator", looking up realm
NULL
    rlm_realm: No such realm "NULL"
  modcall[authorize]: module "suffix" returns noop for request 0

my users file contain:
"PC-01\\Administrator" User-Password == "passwd"

how can I avoid this value PC-01 ?, its really annoying, I would like to
have only real user, PC-01 is "my computer -> properties -> computer name ->
full computer name". I would like to have only username (with no matter of
case sensitive). sth like
"administrator" User-Password == "passwd"

2.
I would like to use only certificate to check wheter or not some computer
should have network connection,
I dont care about login or password,
if client has a valid cacert.pem installed on pc (windows xp) it should
grant acces to network, is it possible to do that?
I tried do sth like:
users:
DEFAULT                Auth-Type := Accept
but it didn't work
the perfect way for me is possiblity to set up something in radiusd.conf and
live file users empty

3.
when I read log from freeradius -X I see that one pc need to have 7requests
in freeradius and in 8-th request is accepted, is it ok?

modcall: entering group authenticate for request 8
