authentication by hostname

[Stefan Sticht]

Hi,

sorry, I am completely new to Radius …

I want to change a FreeRadius server to authenticate a few hosts by their hostnames. 
The hostnames would be stored in a config file.

How could I do this?

This is the authentication request:

rad_recv: Access-Request packet from host 10.10.10.21 port 54285, id=145, length=347
       Framed-MTU = 1480
       NAS-IP-Address = 10.10.10.21
       NAS-Identifier = "HP-2520-24-PoE"
       User-Name = "host/MYHOSTNAME"
       Service-Type = Framed-User
       Framed-Protocol = PPP
       NAS-Port = 1
       NAS-Port-Type = Ethernet
       NAS-Port-Id = "1"
       Called-Station-Id = "84-34-97-de-df-80"
       Calling-Station-Id = "00-1f-29-98-8d-41"
       Connect-Info = "CONNECT Ethernet 100Mbps Full duplex"
       Tunnel-Type:0 = VLAN
       Tunnel-Medium-Type:0 = IEEE-802
       Tunnel-Private-Group-Id:0 = "201"
       EAP-Message = 0x0201001401686f73742f544344452d3030303131
       Message-Authenticator = 0xe06791a76c819a3dc0f89c8baf2df141
       MS-RAS-Vendor = 11

Thanks for any help!

Take care,

Stefan
