EAP-TTLS success

Hi all, I found the issue for below error "EAP-request timed out OR EAP-response to an unknown EAP-request" --- NAS was not responding with the state attribute received from radius server. As soon as we fixed this at NAS, it went through all the steps required to authenticate an user using TTLS-MSCHAPV2. My plaform was Solaris 10, with freeradius version 1.1.3 Thanks all for your valuable input. Rafi
