FreeRadius - Cisco 7204 - L2TP Tunnel
Hi all I’m having major issues with getting Freeradius to authenticate from a Cisco 7204 that is terminating an L2TP tunnel and sending radius auth to a FreeRadius server. Using a default install of Freeradius and configuring it to accept auth requests from the Cisco in clients.conf it just fails on authentication. Even though the username and password in the users files is correct, proven using radtest. From radius -X without changing any config options it gives me Login is incorrect sending a plain text password. No matter what I change in the config files it always fails. I've tried adding Auth-Type's to the users entry such as Local and this gives me things like no password is configured for the user. Removing the "Default Auth-Type" from the top of the users file and setting an Auth-Type in the users entry gives me no Auth-Type set. Really not sure where the error is. So I guess my question is does anyone use FreeRadius to authenticate from a Cisco 7200 series with success? If so is it possible to supply: - The virtual template section that specifies the ppp authentication? - A copy of the radius.conf file? - The users file with an example users entry that works. Then I can see if I've got it all setup correctly. This used to work fine when I was using a Linux server to terminate the L2TP tunnel, I used L2TPNS to do the termination and it sent radius authentication to the FreeRadius server.

So processing stops here, and never reaches the desired entry: > [EMAIL PROTECTED] Auth-Type = Local, User-Password == "mysecret" > Service-Type = Framed-User, > Framed-Protocol = PPP, > Framed-Address = 10.0.0.1, > Framed-Netmask = 255.255.255.255, > Framed-Compression = Van-Jacobsen-TCP-IP So, you can either add a Fall-Though = Yes to the PPP entry, or delete it (since you've got the attributes defined on the users entry anyway you don't need it, or the Framed-Protocol match further up). Personally I tend to do: cp users users.example >users ...and start with a clean slate, reading the examples from the old file. FYI the users file in CVS has by default none of these semi-historic uncommented examples. - List info/subscribe/unsubscribe?

Realm question..
Hi all We have a radius setup that we use to authenticate our own adsl users as well as proxying radius to 2 other sources. Our own radius entries use a realm after each username, a typical entry is: [EMAIL PROTECTED] Password == secret Service-Type = Framed-User, Framed-Protocol = PPP, Framed-Address = 10.0.0.3, Framed-Netmask = 255.255.255.255, Framed-Compression = Van-Jacobsen-TCP-IP ### Is there a way of getting radius to authenicate on the username before the @ sign and ignore the realm? Obviously if the realm is one that we proxy then it should be proxied as such and any that aren't in the proxy.conf file authenticated locally. This may sound like an odd request but in the case of users typing the realm incorrect but the username is Ok they can be authenticated still. Since we only get sent authentication requests from realms that belong to us or the people we proxy for locally it doesn't really matter what the realm is, the user still has to have the correct password to authenticate. In the case the user is one we proxy and the user types the realm incorrect then they just won't be authenticated since it wouldn't be proxied and the username would not exist in our radius users file, this is fine. I've tried adding "strip" to the LOCAL entry in proxy.conf and also just adding the entry: user1 Password == secret Service-Type = Framed-User, Framed-Protocol = PPP, Framed-Address = 10.0.0.3, Framed-Netmask = 255.255.255.255, Framed-Compression = Van-Jacobsen-TCP-IP ### to the radius users file but it won't authenticate.

RE: Realm question..
>> Is there a way of getting radius to authenicate on the username before >>the @ sign and ignore the realm? > Yes, but you have to edit the "users" file to get rid of the >"@realm" portion, and configure the realms as LOCAL ones. The object is to not to have to configure any realms as local. So that Radius will try to auth any realm that isn't to be proxied. If I have a user whose username is [EMAIL PROTECTED] I can easily specify arealm.com as local. But if by mistake the user types the username as [EMAIL PROTECTED] auth will just fail because the realm isn't specified in proxy.conf. > What does debugging mode say? Exactly what you'd expect it to say if the realm isn't in proxy.conf: # rad_recv: Access-Request packet from host 127.0.0.1:33499, id=115, length=68 User-Name = "[EMAIL PROTECTED]" User-Password = "acc355" NAS-IP-Address = 255.255.255.255 NAS-Port = 1645 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 2 modcall[authorize]: module "preprocess" returns ok for request 2 modcall[authorize]: module "chap" returns noop for request 2 modcall[authorize]: module "mschap" returns noop for request 2 rlm_realm: Looking up realm "arealm.com" for User-Name = "[EMAIL PROTECTED]" rlm_realm: No such realm "arealm.com" modcall[authorize]: module "suffix" returns noop for request 2 rlm_eap: No EAP-Message, not doing EAP modcall[authorize]: module "eap" returns noop for request 2 modcall[authorize]: module "files" returns notfound for request 2 modcall: group authorize returns ok for request 2 auth: No authenticate method (Auth-Type) configuration found for the request: Rejecting the user auth: Failed to validate the user. Login incorrect: [EMAIL PROTECTED]/acc355] (from client localhost port 1645) Delaying request 2 for 1 seconds Finished request 2 ## The user doesn't exist as the entry in users just has the username as "user1" and the request is sending [EMAIL PROTECTED] I want radius to first check to see if the request needs to be proxied. If not then authenticate it locally no matter what the realm is but before authenticating it strip off the realm and just use everything before the @ sign as the username.

In my case the xsupplicant software provides an own SHA1 library with the same function names as the openssl library. However, the SHA1 functions provided by xsupplicant are not in all cases equivalent to the one of the openssl. Therefore you need to remove the SHA1 library object files from the linking process of xsupplicant (it's just a change in the makefile). I have posted this error to the xsupplicant mailing list. But it has not been resolved since you have now the same problem I did.
