Authenticated Registration by RADIUS problem

[Gabriel_Bagita]

I've configured a captive portal for authenticated registration. When I check the credential against the local DB, it works fine. I have a RADIUS server, which we use to authenticate users for EAP-PEAP and it works also fine. But, when I try to use it for checking the credential entered for authenticated registration, the RADIUS server returns an Access Reject answer. Does somebody has an idea, where could be a problem?

You will need access the the RADIUS server's event log to tell.

I'd like to do it, but I can't. I have no access.
