I am trying to terminate vpdn sessions through our cisco 3825 using freeradius. I am new to this whole process and I was hoping to get some assistance with the missing configuration. Below is the error message I am receiving when trying to authenticate via the router. rad_recv: Access-Request packet from host 64.34.66.5 port 1645, id=19, length=135 Framed-Protocol = PPP User-Name = "aewais@domain.com" User-Password = "password" Calling-Station-Id = "bas203300000455" Connect-Info = "1000000000" NAS-Port-Type = Virtual NAS-Port = 532 NAS-Port-Id = "Uniq-Sess-ID532" Service-Type = Framed-User NAS-IP-Address = 64.34.66.5 # Executing section authorize from file /etc/freeradius/sites-enabled/default +- entering group authorize {...} ++[preprocess] returns ok ++[chap] returns noop ++[mschap] returns noop ++[digest] returns noop [suffix] Looking up realm "domain.com" for User-Name = "aewais@domain.com" [suffix] No such realm "domain.com" ++[suffix] returns noop [eap] No EAP-Message, not doing EAP ++[eap] returns noop [files] users: Matched entry DEFAULT at line 172 ++[files] returns ok ++[expiration] returns noop ++[logintime] returns noop [pap] WARNING!
