Please Help- FreeRADIUS1.0.1 sending Access-Reject/no EAP-Message attribute

Dear all, I'm using a FreeRADIUS1.0.1 with hostap source code+xsupplicant.When I use EAP/TLS authentication,after running for 24-26 hours , authentication fails.In hostap, I'm getting a RADIUS packet with Access-Reject/no EAP-Message attribute.When I surfed the net I saw that RADIUS should not sent such a message combination. Reference:http://www.drizzle.com/~aboba/AAA/issues3.html Then why is it happening .Is it a bug of FreeRadius1.0.1.Can anyone please help me. Thanks in advance Regards Preethi
