Problem to copy attribute Tunnel-Private-Group-ID to inner-tunnel (eap) - freeradius 3.0.7 - Freeradius-Users

2 Mar 2015

      Hello guys,

In the last version freeradius (3.0.7), some attributes are not visible
inside the inner-tunnel, like as Tunnel-Private-Group-ID, this attribute
have de VLAN ID from client.

Before I was using freeradius version 3.0.1 and always work fine, in 3.0.7
version this attribute is visible in default server, but it not is copied
to inner-tunnel.

In EAP configuration session, when I upgrade from 3.0.1 to 3.0.7, I changed
the configs to:

in eap module:

use_tunneled_reply = no

And uncomment in inner-tunnel post-auth from:

        update {
                &outer.session-state: += &reply:
        }

and

        update outer.session-state {
                MS-MPPE-Encryption-Policy !* ANY
                MS-MPPE-Encryption-Types !* ANY
                MS-MPPE-Send-Key !* ANY
                MS-MPPE-Recv-Key !* ANY
                Message-Authenticator !* ANY
                EAP-Message !* ANY
                Proxy-State !* ANY
        }

In accord with documentation, this replace use_tunneled_reply = yes in
3.0.5 version

In debug below we can see the missing attribute Tunnel-Private-Group-ID in
EAP check, this produce de error: “ERROR: Failed retrieving values required
to evaluate condition”
