realm based proxy not working

1 Feb 2006

      Hi Folks

I'm trying to get my Radius server handling requests for other realms now,
and have been unsuccessful in the process. Despite my best efforts, the
radius server ignores that the login realm is incorrect and attempts to
authenticate the user against my LDAP tree.

startup with debug shows it's being loaded;

Starting - reading configuration files ...

        authhost        = LOCAL
        accthost        = LOCAL
        strip
}

Radiusd.conf has

# PROXY CONFIGURATION

$INCLUDE  ${confdir}/proxy.conf

#realm module
'username@realm'
        #
        realm suffix {
                format = suffix
                delimiter = "@"
                ignore_default = no
                ignore_null = yes
        }

authorize {
                preprocess
                suffix
                auth_log
                eap
                ldap1
                ldap2
                ldap3
                ldap4
                ldap5
                ldap6
                ldap7
                }

The logon is reaching the radius server with the correct realm, can anyone
shed any light on this behaviour?

I've tried it with our local domain both above and below the default
entries, but without luck.
