Does anyone here have working inner tunnel proxying with freeradius 2.0.x?

Still having troubles with doing EAP-PEAP-MSCHAPv2 authorization.
Switched to FreeRadius 2.0.1 from 1.1.7.

  I think the issue was introduced recently.  Try editing
src/main/event.c, function request_post_handler()

...
        if (request->root->proxy_requests &&
            /* !request->proxy &&  */         // comment out this line
            !request->in_proxy_hash &&        // add this line
            (request->reply->code == 0) &&
            (request->packet->dst_port != 0) &&
            (request->packet->code != PW_STATUS_SERVER)) {
...

  Re-build && install.  See if that helps...

Thanks for the tip.
successfully_proxied_request() also needs patching:

/* * If it was already proxied, do nothing. * * FIXME: This should really be a serious error. */ /* if (request->in_proxy_hash || request->proxy) { */ if (request->in_proxy_hash) { return 0; }

AFAIU this function relies on empty request->packet, but it is not empty because has been filled in eappeap_process():

/* * Seed the proxy packet with the * tunneled request. */ rad_assert(request->proxy == NULL); request->proxy = fake->packet;


The second oddity: when setting "proxy_tunneled_request_as_eap = no" proxying is not working because no inner MSCHAPv2 request extracted. Debug looks like this:

Wed Feb 6 00:33:09 2008 : Debug: PEAP: Calling authenticate in order to initiate tunneled EAP session. Wed Feb 6 00:33:09 2008 : Debug: WARNING: Unknown value specified for Auth-Type. Cannot perform requested action.

Solution is quite simple: write down the following in proxy-inner-tunnel file after authorize {} section:

authenticate { eap }


module_authenticate() is being called in eappeap_process() to extract MSCHAPv2 request and when no authenticate section in virtual server proxying will fail. IMHO it will be useful to have these lines in example proxy-inner-tunnel as a comment for "proxy_tunneled_request_as_eap" set to "no". Maybe someone will run into the same issue and spend several hours or days to figure out how to fix this.
