The config is: in users : DEFAULT Client-IP-Address == 10.10.10.2 , Auth-Type := Vpn, Autz-Type := Vpn, Post-Auth-Type := Vpn, Session-type := Vpn in radius.conf: ldap ldap-Vpn{ .... password_attribute = userPassword password_header = "{clear}" } authorize { chap Autz-Type Vpn{ ldap-Vpn chap } } authenticate { Auth-Type CHAP { chap } Auth-Type Vpn{ chap } } .... what is my mistake? should I do any other config or change ? please any idea?
