RE: more EAP/TTLS trouble
by Aman Arneja 30 May '12

Hi Steve Microsoft supports EAP TTLS in our upcoming is release of Windows 8 . That said PEAP MSChapv2 is as modern as an EAP TTLS and is a very widely and simply deployed method. I have personally used the freeradius peap mschapv2 pretty much out of the box. As far as the certificate error you saw earlier that was due to the nature of design of a modern secure authentication method which gave supported security feature like Server Certificate Validation enabled by default. If you just go through the net you will find tonnes of peap mschapv2 working eap.conf's and I suggest you compare yours to the ones available for the authentication to work. Also if you are looking for ttls only you can test with the beta of windows 8 and become one of our early adopters when it releases. Thanx and Regards Aman Arneja Sent from my Windows Phone ------------------------------ From: Steve Hopps Sent: 5/30/2012 6:23 PM To: FreeRadius users mailing list Subject: Re: more EAP/TTLS trouble We're trying to use an access point configured for wpa2 using freeradius to authenticate with openldap. For Android and Linux it works out of the box with eap/ttls and pap. So we used Pam cause it already works with ldap. I didn't know other encryption types wouldn't work with Pam. IPhones work with a custom config profile that's easily installed. However, our most significant hurdle is windows machines. Who would have guessed??? For some stupid reason Microsoft doesn't care about supporting all modern encryption standards. Making our staff pay for SecureW2 isn't an option and XSupplicant doesn't work reliably yet in 64bit Win7. So I'm back to trying to get mschapv2 working with peap. This seems impossible.

FreeRadius autoreply the access chanllenge
by sam 30 May '12

30 May '12

I setup the pam_radius_auth.so in pam.d/sshd to verify the user using the remote Radius server. As the protocol, When used in an Access-Challenge, it MAY indicate a dialog message to prompt the user for a response. like following flow 1) server sends the access-challenge message with reply-message YOUR PASSWORD HAS EXPIRED. PLEASE ENTER THE NEW PASSWORD 2) client sedns back the access-Request message. 3) server sends another access-challenge message with reply-message PLEASE RE-ENTER THE NEW PASSWORD AGAIN FOR VERIFICATION 4) client sedns back the access-Request message again. I think the message flow is right, but at the point-2 and point-4, the prompt should be popped and ask us to input the passwd. However, our freeradius sends the access-Request automatically. Just checked the code, and not find the problem when doing access-chanllenge. the function rad_converse() calls pam_get_item(). I think it is only place to suspect, can this function pop the prompt? anyone encounter this problem? /* It's full challenge-response, we should have echo on */ retval = rad_converse(pamh, PAM_PROMPT_ECHO_OFF, challenge, &resp2challenge); +++processing access-chanllenge code+++ while (response->code == PW_ACCESS_CHALLENGE) { attribute_t *a_state, *a_reply; char challenge[BUFFER_SIZE]; /* Now we do a bit more work: challenge the user, and get a response */ if (((a_state = find_attribute(response, PW_STATE)) == NULL) || ((a_reply = find_attribute(response, PW_REPLY_MESSAGE)) == NULL)) { /* Actually, State isn't required. */ _pam_log(LOG_ERR, "RADIUS Access-Challenge received with State or Reply-Message missing"); retval = PAM_AUTHINFO_UNAVAIL; goto error; } /* * Security fixes. */ if ((a_state->length <= 2) || (a_reply->length <= 2)) { _pam_log(LOG_ERR, "RADIUS Access-Challenge received with invalid State or Reply-Message"); retval = PAM_AUTHINFO_UNAVAIL; goto error; } memcpy(challenge, a_reply->data, a_reply->length - 2); challenge[a_reply->length - 2] = 0; DPRINT(LOG_DEBUG, "Got Prompt=%s",challenge); /* It's full challenge-response, we should have echo on */ retval = rad_converse(pamh, PAM_PROMPT_ECHO_OFF, challenge, &resp2challenge); <<<<< here /* now that we've got a response, build a new radius packet */ build_radius_packet(request, user, resp2challenge, &config); /* request->code is already PW_AUTHENTICATION_REQUEST */ request->id++; /* one up from the request */ /* copy the state over from the servers response */ add_attribute(request, PW_STATE, a_state->data, a_state->length - 2); retval = talk_radius(&config, request, response, resp2challenge, NULL, 1); PAM_FAIL_CHECK; DPRINT(LOG_DEBUG, "Got response to challenge code %d", response->code); } +++code+++ +++log+++ May 28 23:12:13 sshd[20729]: pam_radius_auth: Sending RADIUS request code 1 May 28 23:12:13 sshd[20729]: pam_radius_auth: DEBUG: getservbyname(radius, udp) returned -745295136.

rlm_python configTuple question
by PENZ Robert 30 May '12

30 May '12

Hi! The python functions should return (return, replyTuple, configTuple). return is one of the following constants #RLM_MODULE_REJECT = 0 # /* immediately reject the request */ #RLM_MODULE_FAIL = 1 # /* module failed, don't reply */ #RLM_MODULE_OK = 2 # /* the module is OK, continue */ #RLM_MODULE_HANDLED = 3 # /* the module handled the request, so stop. */ #RLM_MODULE_INVALID = 4 # /* the module considers the request invalid. */ #RLM_MODULE_USERLOCK = 5 # /* reject the request (user is locked out) */ #RLM_MODULE_NOTFOUND = 6 # /* user not found */ #RLM_MODULE_NOOP = 7 # /* module succeeded without doing anything */ #RLM_MODULE_UPDATED = 8 # /* OK (pairs modified) */ #RLM_MODULE_NUMCODES = 9 # /* How many return codes there are */ replyTuble are the attributes which are send to the requesting NAS, but I couldn't find out what configTuple is exactly. I currently only pass an () and it works. Is it the same as "update control" and setting variables in the normal config files? What I would like to do is to provide a variable which can be used in the config file after calling the python module to compare it against "%{TLS-Client-Cert-Subject}" as I don't see a possible to get this variable in the python module to do the compare there.

Address already in use but server is not running
by Michael Aldridge 29 May '12

29 May '12

I recently had to install debian 6.0 on one of my servers after a hard drive crash, and while I had freeradius running before, I can't seem to get it running now. I ran sudo apt-get install freeradius and hit enter to accept the additional packages, and I also installed dialup admin with the intention of getting to it after getting freeradius running, but now I am running into trouble with starting freeradius. The install completed without errors, but running sudo ./freeradius -X produces the following: Failed binding to authentication address * port 1812: Address already in use /etc/freeradius/radiusd.conf[240]: Error binding to port for 0.0.0.0 port 1812 I can post the full contents of the debug dump, but this appears to be the only point at which an error is encountered. I am quite sure that there is not an instance already running, so I don't know what else could be using the port. Any ideas?

How do I set a reply attribute that is not sent in the Access-Accept
by niall el-assaad 27 May '12

27 May '12

Hi, I want to define my own attribute that I set in the inner server, but then check it in the outer config. The problem is that I don't want free radius to send it in the access-accept message at the end. I remember reading somewhere I could define a RADIUS dictionary with certain numbers that FreeRADIUS would not send externally, but after looking for an hour I can't find it. Would anyone be able to point me in the right direction. Much appreciated, niall
