Freeradius proxy support

[Ilavajuthy Palanisamy]

Hi Alan,

I have set the below configuration in proxy.conf and it is not working. I
need help in fixing it.

home_server ssid_700 {
        type = auth
        ipaddr = 16.108.158.172
        port = 1812
        secret = testing123
        require_message_authenticator = yes
        response_window = 20
        zombie_period = 40
        revive_interval = 120
        status_check = status-server
        check_interval = 30
        num_answers_to_alive = 3
        coa {
                # Initial retransmit interval: 1..5
                irt = 2

                # Maximum Retransmit Timeout: 1..30 (0 == no maximum)
                mrt = 16

                # Maximum Retransmit Count: 1..20 (0 == retransmit forever)
                mrc = 5

                # Maximum Retransmit Duration: 5..60
                mrd = 30
        }
}

home_server_pool ssid_700_pool {
        type = fail-over
        home_server = ssid_700
}

realm ssid_700_realm {
        auth_pool = ssid_700_pool
        nostrip
}

if ( Colubris-AVPair == "ssid=uww_700" ) {
        update control {
                Proxy-To_Realm := "ssid_700_realm"
        }
}

#realm NULL {
#       authhost        = radius.company.com:1600
#       accthost        = radius.company.com:1601
#       secret          = testing123
#}

#
#  This realm is for ALL OTHER requests.
#
#realm DEFAULT {
#       authhost        = radius.company.com:1600
#       accthost        = radius.company.com:1601
#       secret          = testing123
#}

With the above configuration, it is not entering the if condition (unlang).
Below is the debug log. It say there is no @  with the user and looking up
realm NULL. I have commented out the realm NULL and realm DEFAULT.


rad_recv: Access-Request packet from host 16.108.159.73 port 56904, id=180,

++[mschap] = noop
++[digest] = noop
[suffix] No '@' in User-Name = "t", looking up realm NULL
[suffix] No such realm "NULL"


What configuration change that i have to do to make it working?
I need to have a home server pool for each of the ssid. I need to do below
kind of setup;

if ( Colubris-AVPair == "ssid=uww_700" ) {
       //use home_server_pool = ssid_700_pool
}

if ( Colubris-AVPair == "ssid=uww_800" ) {
       //use home_server_pool = ssid_800_pool
}

Also need to know where the unlang (the if condition) needs to be
specified? Does it needs to be specified inside any block?

Thanks,
Ila.
