Guys, Having a problem with CHAP and freeradius (PAP works ok, and I'm using clear text passwords, I have this in the check table "Cleartext-Password := password"). I get this in the debug [chap] login attempt by "xxxxxxxxxx" with CHAP password [chap] Using clear text password "password" for user xxxxxxxxxx authentication. [chap] Password check failed I've tried with radtest using type chap, and it works fine, I'm thinking there's a problem with the access-request (but I don't control that end, it's a large Telco in AU). My radius box is a CentOS box with freeradius2-2.1.12-5.el5 installed. What I want to know is, do I have enough attributes in this access-request for CHAP to work? User-Name = "xxxxxxxxxx" CHAP-Password = 0x01345dcc75b35990d8b99bb0d0b0be3593 NAS-IP-Address = xxx.xxx.xxx.xxx NAS-Port = 1821857408 Service-Type = Framed-User Framed-Protocol = GPRS-PDP-Context 3GPP-IMSI = "50501xxxxxxxxxx" 3GPP-PDP-Type = 0 3GPP-GGSN-Address = xxx.xxx.xxx.xxx 3GPP-NSAPI = "5" Called-Station-Id = "apn" Calling-Station-Id = "xxxxxxxxxx" NAS-Identifier = "SFL9" Acct-Session-Id = "0A380612[]xxxxxxxxxxxxxxxx" NAS-Port-Type = Virtual I don't see one of these "CHAP-Challenge" from the NAS I'm not sure what pieces freeradius needs to munge together to come up with the same password hash that rolls in from the Telco. I didn't post the full debug just so I didn't have to redact so much. If this access request turns out to be ok, I can post the full debug. Mark.
