I was newly joined in freeradius developers mailing list, first i will introduce my self briefly, i have to develop a radius server which authenticate the users with their finger print, so please tell me what i have to do for that now i am going through some examples how the authentication is made with username and passwords but i was unable to find how to integrate this finger print authentication in radius server, so please help me regarding this.

That's because RADIUS does username / password authentication. If you have a fingerprint reader that converts fingerprints to usernames/passwords for RADIUS, then it's just username/password authentication. Alan DeKok.
