User Authenticated even when username not given in USERS file (EAP-TLS)

Hi , I am using EAP-TLS for authentication, USERs are getting authenticated even when I have not defined the user in USERS file. I have not changed any default configuration. Certificates are made by the makefile provided. Windows client is having both root & client certificates installed. radiusd -X log -> * http://pastebin.com/hZWubqWD* 1. Is this behavior normal. 2. Should I have to use DEFAULT Auth-Type := Reject at the end of users file ? Thanks & Regards,
