Hello,Alan DeKok!Thank you very much for the clear answer.
Now i encounter a new problem and would be very appreciated if you could give
me some advice.
My problem:The authentication is failed.Part of the information from freeradius server is:
           ...
           [eap]Handler failed in EAP/md5
           [eap]Failed in EAP select
           ++[eap]returns invalid
           Failed to authenticate the usr
           Using Post-Auth-Type Reject
           +-entering group REJECT{...}
           [attr_filter.access_reject]   &! nbsp;  expand: %{User-Name} -> anh
            attr_filter:Matched entry DEFAULT at line 11
           ++[attr_filter.access_reject] returns updated
           Delaying reject of request 6 for 1 seconds
           Going to the next request
           ...
