Option 82 DHCP Snooping + Freeradius auth of DHCP requests

Hello!
I'm trying to setup network with DHCP Snooping Option 82 functionality
+ Freeradius auth for DHCP requests.
DHCP server which receives DHCP packets from cisco switch "dhcp relay"
is Mikrotik RouterBoard.
freeradius2-2.1.7-7.el5. Also updated dictionary from new 2.1.10 package
"Option 82" works perfectly without radius simply giving IPs to all requests.

Mikrotik RB sends Option 82 request to freeradius with Redback vendor
attributes.
Also i've working eap-ttls and sql auth on same Freeradius server. But
for simplicity i tried to used "files" auth method,
which i think should work simultaniously depending on where user name
where found and to which methods it applies.
Please correct me if i'm wrong. I can't see files method in debug, by
the way it says that it can't find auth method for username O_O :(.
I don't know what to do else. Freeradius should receive Username
Remote and Circuit IT and send Request-Accept with framed-ip from
mikrotiks dhcp pool

So here are my debugs and username configured in users file:

Atributes seen in mikrotik:
ARemote-id: 0:6:0:d:ed:21:a4:80
ACircuit-ID:   0:4:0:2:0:0

Atributes sniffed from packet seen in hex:
Remote-ID: 0006000ded21a480 this is inside: VSA: l=10
t=Agent-Remote-Id(96): \000\006\000\r\355!\244\200
Circuit-ID:   000400020000        this is inside: VSA: l=8
t=Agent-Circuit-Id(97): \000\004\000\002\000\000


00:0C:42:40:40:38  Agent-Remote-Id   = "0006000ded21a480"
<============= Here i've tried different formats of these 2 atributes
, sniffed with wireshark, with columns without
                            Agent-Circuit-Id  = "000400020000",
                                  |  But as i have sniffed traffic and
saw radius debud it accepts in different format with slashes
                            Framed-IP-Address = 192.168.3.155
                               |  hope those are unreadable ASCII
characters as i was told and

Here is radius debug output for first request-reject packets:
