free radius 1.1.6 -eap-tls authentication

Dear all My EAPTLS is working with free radisu 1.1.6 as i did every installation starts from zero Thanks for all for the help. I have few quires for free radius as i was using navis radius. 1 Where will i find the log of the authentication like.... username login ok...or login failed 2 One user\'s certificate if I installed in other user\'s laptop it works.I want one user certificate should work in one laptop only. 3 In users file i havn\'t added any certificate name as it is eap-tls.So if i want to remove the user from n/w i don\'t have control.Is ther any method like i can add the certificate names in users file then only it should work Regards Anoop
