Hi, At first, sorry for my english, (I'm spanish :). I've just installed freeradius, and I would like to use PEAP-MS-CHAP authentication, I've configured needed files, and when I try to start freeradius, with the debug option, y receive this messages: tls: private_key_file = "/ca/key_radius.pem" tls: certificate_file = "/ca/cert_radius.pem" tls: CA_file = "/ca/cacert.pem" tls: private_key_password = "radius" tls: dh_file = "/ca/dh" tls: random_file = "/ca/random" tls: fragment_size = 1024 tls: include_length = yes tls: check_crl = no tls: check_cert_cn = "(null)" rlm_eap: Loaded and initialized type tls rlm_eap: Failed to link EAP-Type/peap: rlm_eap_peap.so: cannot open shared object file: No such file or directory radiusd.conf[9]: eap: Module instantiation failed. linux:/lib # I don't have too much experience in linux enviroments (this is a Suse Interprise Server 9), and I don't have idea about what is happening. I would need some kind of help, please. Thanks a lot !!! María.

I note that 18432 is hex 0x7200. I suspect that > the NAGIOS people missed a 'htons()' somewhere, and the field should be > 0x0072. Alan, You are exactly correct. Good catch. For mailing list archives, the simplest patch I came up with: /* copy the first 20 bytes of the radius header. this size is static * per RFC. */ radhead->rad_length = htons(radhead->rad_length); memcpy(packet,(char *)radhead,20); radhead->rad_length = ntohs(radhead->rad_length); rad_length is used elsewhere, so this is done to avoid breaking anything else. Thanks for your help! (I wonder how this always worked for xtradius from the same machine?)

rlm_eap: SSL error
by James Lever 19 Jan '07

19 Jan '07

Hi List, FreeRADIUS 1.1.4 on FreeBSD (5-STABLE), Apple Airport Extreme NAS, MacBook Pro client, WPA2 Enterprise with 2k keys. I'm having the much mentioned but very hard to get real information about error below: Wed Jan 17 08:00:11 2007 : Error: TLS_accept:error in SSLv3 read client certificate A Wed Jan 17 08:00:11 2007 : Error: rlm_eap: SSL error error: 00000000:lib(0):func(0):reason(0) Wed Jan 17 08:00:11 2007 : Error: rlm_eap: SSL error error: 00000000:lib(0):func(0):reason(0) Wed Jan 17 08:00:11 2007 : Auth: Login OK: [wireless- client.jamver.id.au] (from client apple-basestation port 255 cli xx- xx-xx-xx-xx-xx) Now, the best explanation I can find on list is that it's safe to ignore the 3 lines of errors, which, although appears to be very accurate in that they have no effect on the running service, should not be there if they are really not errors. Can anybody explain what is actually causing these errors (and why) and what would be required to silence them? cheers, James

How to send tome clients to the same detail file
by Angel L. Mateo 18 Jan '07

18 Jan '07

Hello, I have a running server with this configuration: detail { detailfile = ${radacctdir}/%{Client-IP-Address}/detail-%Y%m%d detailperm = 0600 } detail auth_log { detailfile = ${radacctdir}/%{Client-IP-Address}/auth-detail-%Y%m%d detailperm = 0600 } I have activated the detail file in the accounting section and the auth_log in the authorize and are working fine. But now I want to send all the logs for requests from a group of clients (defined as a huntgroup) to the same files, and the request for all other clients as now (classified with the IP address of the client). Is there any way to redefine this files for a set of clients? -- Angel L.

EAP-TLS/seg fault with 4096 bit keys
by James Lever 18 Jan '07

18 Jan '07

Hi again list, Another issue I have had in setting up a WPA2 Enterprise environment is that I can get it to work as expected with 2k keys, however, if I go to 4k keys, freeradius 1.1.4 loads properly but seg faults when handling a 4k key request. The environment is Apple Airport Extreme base station, and MacBook Pro client wth FreeRADIUS 1.1.4 under FreeBSD 5-STABLE. As soon as I migrate back to 2k keys it again works as expected. Can anybody make any suggestions on how to debug this? cheers, James

Feeding an LDAP replyItem to an MS-CHAPv2 ntlm_auth request
by Haas Florian 18 Jan '07

18 Jan '07

Since this is my first post to this list, hello everyone. I do apologize if this question has been asked before; unfortunately I've been unable to find this information in the list archives. I have a working setup with Windows XP clients, MSAD, FreeRADIUS 1.1.0 running on SLES 10, and Enterasys switches. Authentication via PEAP and MS-CHAPv2. Everything works perfectly fine when a Windows user logs on; ldap module looks up the user, mschap authenticates, client is dropped into the right VLAN... beautiful. However, what I am also trying to achieve is to force the client into a specific VLAN when no user is logged on (this corresponds to the "Authenticate as computer when computer information is available" option in the "Authentication" tab of the Windows connection properties dialog). The tricky part is that XP's supplicant, which supplies the username as "DOMAIN\\Username" while a user is logged on, supplies a username in the form of "host/computername.my.domain" otherwise -- this corresponds to the servicePrincipalName attribute on the machine's object in MSAD. This is of course a format that ntlm_auth can't deal with. So, my approach is this: 1. When authorizing, look up the LDAP DN using a filter that checks both sAMAccountName and servicePrincipalName: radiusd.conf: modules { # [...] ldap { # [...] filter = "(|(sAMAccountName=%{Stripped-User-Name:-%{User-Name}})(servicePrincipalName=%{S tripped-User-Name:-%{User-Name}}))" # [...] } } } 2. While authorizing, retrieve the value of the sAMAccountName from LDAP. For this purpose, I have the following entry in the LDAP Attribute map: replyItem MSAD-SAM-Account-Name sAMAccountName 3. When authenticating, feed mschap's ntlm_auth the MSAD-SAM-Account-Name if it is available: modules { # [...] mschap { # [...] ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{MSAD-SAM-Account-Name:-%{Stripped-User-Name:-%{User-Name:-None}}} --challenge=%{mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00}" # [...] } } } >From the debug logs, it appears such that the computer's LDAP object is looked up successfully (using the servicePrincipalName host/testpc.demo.com) and that the MSAD-SAM-Account-Name replyItem is set correctly (to "TESTPC$"). However, ntlm_auth is invoked with the username None instead, so it appears that the LDAP replyItems are not made available to the mschap authentication module. rlm_ldap: performing search in dc=demo,dc=com, with filter (|(sAMAccountName=host/testpc.demo.com)(userPrincipalName=host/testpc.demo.com)( servicePrincipalName=host/testpc.demo.com)) rlm_ldap: looking for check items in directory... rlm_ldap: looking for reply items in directory... rlm_ldap: Adding sAMAccountName as MSAD-SAM-Account-Name, value TESTPC$ & op=11 rlm_ldap: user host/testpc.demo.com authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns ok for request 5 modcall: leaving group authorize (returns updated) for request 5 rad_check_password: Found Auth-Type EAP auth: type "EAP" Processing the authenticate section of radiusd.conf modcall: entering group authenticate for request 5 rlm_eap: Request found, released from the list rlm_eap: EAP/mschapv2 rlm_eap: processing type mschapv2 Processing the authenticate section of radiusd.conf modcall: entering group MS-CHAP for request 5 rlm_mschap: No User-Password configured.

I'm almost certain that I am missing something very obvious. Would someone be kind enough to enlighten me? Thanks very much. Florian -- Mag.(FH) Florian G.
