Description (partial)

Symptom:
The PPP PAP ACK message SHOULD be passed from Radius REPLY-MESSAGE AVPair directly into the PPP PAP ACK message.
See below code:
    void ppp_lcp_pap_aaa_response_for_peer_success (ppp_lcp_idb_type *lcp_idb)
    {
        ppp_ma_idb_type  *ma_idb = ppp_lcp_idb_ma_idb_get(lcp_idb);
        if ((ma_idb->srg_idb == NULL) || !(ma_idb->srg_idb->cp_flags & SRG_LCP_FORCE_OPENED))
           {
            	ppp_lcp_pap_send_response(lcp_idb, PPP_PAP_CODE_ACK,  NULL); /* No message needed */           
                  /*But actually, yes we need the message to be RFC compliant */
           }
            ppp_lcp_auth_of_peer_success(lcp_idb);
    }
