Some RLM_MODULE_INVALID events are not logged via detail
by Boris Lytochkin 31 Oct '19

31 Oct '19

Hi. We're trying to catch a bug in some vendor's equipment resulting in "Login incorrect (eap: EAP requires the State attribute to work, but no State exists in the Access-Request packet.)" error appearing in the log and subsequent Access-Reject sent from RADIUS server (version 3.0.15 with a bit of pull requests still not merged :). It seems that this configuration does not catch that particular Access-Reject into detail(ed) log: ================== detail auth_log { header = "%t (%I)" filename = ${radacctdir}/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/auth-%Y%m%d log_packet_header = yes permissions = 0640 } authenticate { Auth-Type EAP { eap { handled = 9999 } if (handled) { auth_log.post-auth # logging is done, return return } # eap module returned OK so we go a bit further perl # Access-Accept/Reject will be logged by authorize section } } post-auth { auth_log Post-Auth-Type REJECT { auth_log } ... } ================== Am I missing something? I took a quick tour though the code and failed to find a place where radiusd decides to **log** " Login incorrect (eap_tls: TLS Alert read:fatal:unknown CA):" into detail and **not to log** "Login incorrect (eap: EAP requires the State attribute to work, but no State exists in the Access-Request packet.)" p/s. Playing around with `handled` in Auth-Type EAP has nothing to do with detailed log as I see the same situation before I tweaked that part of the configuration. pp/s. Is there a way to print packet identifier as it is sent over the wire into detailed log? I made a trivial patch for that seeing no documented way exist to do that: =============== --- a/src/modules/rlm_detail/rlm_detail.c +++ b/src/modules/rlm_detail/rlm_detail.c @@ -336,6 +336,7 @@ static int detail_write(FILE *out, rlm_detail_t *inst, REQUEST *request, RADIUS_ } #endif } + WRITE("\tPacket-Identifier = %d\n", packet->id); WRITE("\tTimestamp = %ld\n", (unsigned long) request->timestamp); WRITE("\n"); =============== -- Boris Lytochkin Yandex NOC +7 (495) 739 70 00 ext. 7671

OCSP Response Signed by other CA
by Mike DiBella 30 Oct '19

30 Oct '19

I'm attempting to add OCSP certificate verification to EAP, but my responder hosts multiple CAs and signs the responses with a cert common to all. I think freeradius is assuming that the signer of the OCSP response will be the same as the signer of the client certificate, and I can't see an option to override this behavior. I've already tried concatenating the OCSP signer to the client trust certificate file, but freeradius still fails validation with "Error: rlm_eap: SSL error error:27069070:OCSP routines:OCSP_basic_verify:root ca not trusted". Any ideas?

deployingradius doc site
by J Kephart 30 Oct '19

30 Oct '19

Hi! At one point, I found a link to a wonderful page that documents every aspect, in great detail, of configuring a FR server. Alas, my bookmarks were lost in a crash, and despite an intensive search, I am unable to locate it again, though I believe it was on the deployingradius site. The wiki doesn't seem to have the detail I need (I'm trying to get a full understanding of how to set up 802.1x), and I recall that document giving that level of detail. Can anyone point me at it? Thanks, -- Jim

Detailed Logging freeradius Request Packets
by Jean-Francois Mousinho 28 Oct '19

28 Oct '19

Hi, I've tried to find a way of detail logging the packets sent by freeradius to the client in the authentication phase but didn't found a way of doing it. Maybe I've not looked correctly so I'm asking if it's actually possible? I was able to log detailed packets sent by the client (Response packets) but not the ones sent by freeradius to the client (except accounting and proxied ones). Thanks for your time.

Re: Authorize access by MAC Address
by Mike DiBella 26 Oct '19

26 Oct '19

I seem to be misunderstanding how authentication and authorization works under FreeRadius. In the default site configuration, I have enabled unix under both the authorize and authenticate sections, and ldap only under authorize. I am using a test client to send an authentication request with a valid User-Name, User-Password, and Calling-Station-Id attributes set. I can see the in logs that the bind is successful and that the search does not return any object matching the filter criteria, as expected. However, an access-accept is still returned to the test client. I am expecting that unix type will only be used for authentication, and that authorization depends on the ldap search being successful, but this does not appear to be the way the configuration is functioning. If I comment out unix from the authorize section of the default site, then access-reject is returned even when the password is valid and the search is successful. Thoughts? rad_recv: Access-Request packet from host 192.168.1.63 port 55161, id=3, length=63 User-Name = "*****" User-Password = "*****" Calling-Station-Id = "5C-95-AE-15-C9-92" # Executing section authorize from file /etc/freeradius/sites-enabled/default +group authorize { ++[preprocess] = ok ++[chap] = noop ++[mschap] = noop ++[digest] = noop [suffix] No '@' in User-Name = "*****", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] = noop [eap] No EAP-Message, not doing EAP ++[eap] = noop ++[unix] = updated ++[files] = noop [ldap] performing user authorization for ***** [ldap] expand: (&(wiFiMAC=%{Calling-Station-Id})(deviceCompliance=0)) -> (&(wiFiMAC=5C-95-AE-15-C9-92)(deviceCompliance=0)) [ldap] expand: CN=Managed Devices,CN=Device Directory,O=DiBella Consulting -> CN=Managed Devices,CN=Device Directory,O=DiBella Consulting [ldap] ldap_get_conn: Checking Id: 0 [ldap] ldap_get_conn: Got Id: 0 [ldap] attempting LDAP reconnection [ldap] (re)connect to *****:389, authentication 0 [ldap] bind as CN=scout,CN=Users,CN=Device Directory,O=DiBella Consulting/***** to *****:389 [ldap] waiting for bind result ...

Update the user filter to match on something other than uid and %{Stripped-User-Name}, e.g. "(&(wiFiMAC=%{Calling-Station- Id})(deviceCompliance=0))" You can change the update{} section to copy any LDAP attributes into RADIUS attributes if you need them. -- Matthew

Authorize access by MAC Address
by Mike DiBella 24 Oct '19

24 Oct '19

I am intend to use FreeRadius to create a network access solution for managed mobile devices. Authentication will be using EAP-TLS with a trusted certificate, but the supplicant identity mapping attribute will be the WiFi adapter's MAC address. I have an LDAP directory with a customized schema that has an object for each managed device with an attribute, wiFiMAC, containing the MAC address and second attribute, deviceCompliance, containing the device's adjudicated policy compliance state. The access request authorization policy should allow access if the device object is found in the directory by MAC address, and deviceCompliance is 0. I've looked over the documentation for LDAP backend configuration, but it is heavy biased towards the authorize-by-user-identity use case. Are there any configuration examples for mapping identity using MAC address? Any examples for adding custom LDAP attributes for access-adjudication?

Using "Tunnel-Private-Group-Id" in linelog
by Burger, Wolfgang 23 Oct '19

23 Oct '19

Dear freeradius-users, I´m using FreeRADIUS Version 2.1.12 to dynamically set the VLAN-ID on some switches by client-mac-address. Works like a charm. I have to modify the logfiles and would like to use linelog. This is my linelog config: linelog vlanlog { filename = ${logdir}/vlanlog permissions = 0600 format = "This is a log message for %{User-Name}" reference = "%{%{Packet-Type}:-format}" Access-Request = "%S: %{reply:Packet-Type} AAA-VLAN-Request for %{User-Name} on %{NAS-Identifier} (%{NAS-IP-Address}) at Port %{NAS-Port-Id}. Put to VLAN %{reply:Tunnel-Private-Group-Id}" Access-Reject = "Rejected access: %{User-Name}" Access-Challenge = "Sent challenge: %{User-Name}" } And this is a Request and Reply for a VLAN-Request: rad_recv: Access-Request packet from host 192.168.1.141 port 1812, id=125, length=320 Framed-MTU = 1466 NAS-IP-Address = 192.168.1.141 NAS-Identifier = "Switch31" User-Name = "0cc47a96a6af" Service-Type = Call-Check Framed-Protocol = PPP NAS-Port = 41 NAS-Port-Type = Ethernet NAS-Port-Id = "41" Called-Station-Id = "00-16-b9-d1-01-d7" Calling-Station-Id = "0c-c4-7a-96-a6-af" Connect-Info = "CONNECT Ethernet 1000Mbps Full duplex" ...
