Reject user without realm

[Marcos Roberto Greiner]

Hi,

I'm trying to use FreeRadius with Realms (using the form user at realm).
Basically, if a user uses user at provider1.com, I want Radius to
authenticate locally. If it's @provider2.com, 3.com, etc, on other
servers listed in proxy.conf.

The problem I'm having is that if a user adds no realm, only the user,
the server is autenticating locally. I wanted it to deny the
authentication. How should I proceed?

Thank you very much,

Roberto



My current setup and radius -X follows.

I'm using MySQL as database (both for users and accounting)

hints file. Added only the following entry:
# The following entry is to be authenticated locally
DEFAULT Suffix == "@domain1.com", Strip-User-Name = Yes
        Hint = "PPP",
        Service-Type = Framed-User,
        Framed-Protocol = PPP

Users file. Commented the entry referencing to Auth-Type = System. No
other changes.

Nothing added to huntgroups

The radius -X output:
