Because of the issues I've been having with authentication with Freeradius I started from scratch and used RPM to remove Freeradius and then re-installed the latest version. I needed to be able to accept both PAP and CHAP authentication, however I couldn't get it to do both and had to by default to get it to auth everyone no matter what the password should be. But I don't see this as ideal. Since I took over the radius server from someone else I'm guessing it had been changed by the previous person to the extend where only a re-install would solve the problem. I read that out of the box Freeradius would accept both PAP and CHAP authentication as long as the password was in clear text and I used "Password ==". So I re-installed Freeradius version freeradius-1.0.1-3.RHEL4.3 and convert all the entries from Auth-Type := Accept to "Password == <password>" where <password> was the users password. On testing I found users still couldn't authenticate by PAP or CHAP, I run "radiusd -X" and from what I could see its because of the Default setting: DEFAULT Auth-Type = System Fall-Through = 1 The NAS is a Cisco 7204VXR and the line for the authentication is: ppp authentication pap chap callin Here is the debug from radius ################ Ready to process requests. rad_recv: Access-Request packet from host 10.0.0.3:1645, id=142, length=95 Framed-Protocol = PPP User-Name = "user1@bb.adslco.com" User-Password = "deabercyap" NAS-Port-Type = Virtual NAS-Port = 1074 Service-Type = Framed-User NAS-IP-Address = 10.0.0.3 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 0 modcall[authorize]: module "preprocess" returns ok for request 0 modcall[authorize]: module "chap" returns noop for request 0 modcall[authorize]: module "mschap" returns noop for request 0 rlm_realm: Looking up realm "bb.adslco.com" for User-Name = "user1@bb.adslco.com" rlm_realm: No such realm "bb.adslco.com" modcall[authorize]: module "suffix" returns noop for request 0 rlm_eap: No EAP-Message, not doing EAP modcall[authorize]: module "eap" returns noop for request 0 users: Matched DEFAULT at 152 users: Matched DEFAULT at 171 users: Matched DEFAULT at 183 modcall[authorize]: module "files" returns ok for request 0 modcall: group authorize returns ok for request 0 rad_check_password: Found Auth-Type System auth: type "System" Processing the authenticate section of radiusd.conf modcall: entering group authenticate for request 0 modcall[authenticate]: module "unix" returns notfound for request 0 modcall: group authenticate returns notfound for request 0 auth: Failed to validate the user.
