Good afternoon I'm a newbie with freeradius and I'm trying to configure a radius proxy server that makes to a server microsoft radius nps. I have a Enterasys C3 switch that sends auth requests to my Freeradius. If the request is for auth a MAC the FR auth locally, but if the request is for auth a windows user (EAP) the FR resend the request to the Microsoft NPS radius server. I use Debian 6.0 and the debian package of FR (version is 2.1.10). The problem is that when the Microsoft RADIUS server returns an accept packet, the freeradius server process dies. But if the answer is reject, the process works properly. When the process dies, only appears in the syslog the following line: "November 11 16:20:35 debian-radius kernel: [2380.591594] freeradius [1749]: segfault at 3934c708 b76fd497 ip sp error 4 in libfreeradius b5ae4970-radius-2.1.10.so [+1 b76ec000 E000]" Can anyone help me? Sorry for my poor English. Best greetings Toni
