[Help-gnu-radius] Authenticate with domain name

[Susumu Ueno]

Hi there

I'm using Redback as NAS and gun-radius 0.96.2.
I want to user(client) authenticate with domain name.
So my users file is something like this:
(Actually, this work with other radius)

DEFAULT Simultaneous-Use 1
                Service-Type = Framed-User,
                Framed-Protocol = PPP,
                Framed-IP-Netmask = 255,255,255,255,
                Framed-Routing = None,
                Framed-MTU = 1500

address@hidden  Password = "pass01"
                Framed-IP-Address = 192.168.100.101,
                Context-Name = local,
                Fall-Through = Yes

address@hidden  Password = "pass02"
                Framed-IP-Address = 255.255.255.254,
                Context-Name = docsis,
                Fall-Through = Yes

This users file makes parse errors both test01 line and test02 line, when 
radiusd started.
Is there any other way to user(client) authenticate with domain name?
The client will send ID:address@hidden and Pass:pass01.
Please anyone help me.


Thanks,
Susumu
