Wouldn't this work?
abc Auth-Type = System, Framed-Protocol = PPP, NAS-IP-Address =x.x.x.x, NAS-Port=29
Service-Type = Framed-User,
...
DEFAULT Auth-Type = Reject, NAS-IP-Address =x.x.x.x, NAS-Port=29
DEFAULT Auth-Type = System, Framed-Protocol = PPP
Service-Type = Framed-User,
...
If you don't want to upgrade to Radius 2.0.1 to get the Auth-Type = Reject,
you could use Auth-Type = Local, Password = <some "impossible" password>.
