Credentials format in Windows suplicant
by joanroldan 23 Jun '11

23 Jun '11

Hi everybody, I have take a look to this post: http://freeradius.1045715.n5.nabble.com/MSCHAP-Authentication-Issue-td27851… And I totally agree with the behaviours described in the table. I have been experiencing the same. If I type the credentials on prompt of Windows supplicant like MYDOMAIN.COM\user password The request is accepted: Fri Jun 10 15:58:51 2011 : Info: ++[eap] returns ok Fri Jun 10 15:58:51 2011 : Auth: Login OK: [IRTA_NT\\jroldan/<via Auth-Type = EAP>] (from client WLC_SSCC port 1 cli 00-26-B6-59-F1-EA) But if I type user(a)mydomain.com password I get the next info: Fri Jun 10 16:11:52 2011 : Debug: Exec-Program output: Logon failure (0xc000006d) Fri Jun 10 16:11:52 2011 : Debug: Exec-Program-Wait: plaintext: Logon failure (0xc000006d) Fri Jun 10 16:11:52 2011 : Debug: Exec-Program: returned: 1 Fri Jun 10 16:11:52 2011 : Info: [mschap] External script failed. Fri Jun 10 16:11:52 2011 : Info: [mschap] FAILED: MS-CHAP2-Response is incorrect Fri Jun 10 16:11:52 2011 : Info: ++[mschap] returns reject Fri Jun 10 16:11:52 2011 : Info: [eap] Freeing handler Fri Jun 10 16:11:52 2011 : Info: ++[eap] returns reject Fri Jun 10 16:11:52 2011 : Info: Failed to authenticate the user. Fri Jun 10 16:11:52 2011 : Auth: Login incorrect (mschap: External script says Logon failure (0xc000006d)): [jroldan(a)irta.es/<via Auth-Type = EAP>] (from client WLC_SSCC port 0 via TLS tunnel) I assume my configuration is fine (extracted from deployingradius.com) because its working by typing credentials in NT format. As the configuration of freeradius is for eduroam purpose it would be nice that user enter the credentials like user(a)domain.com, and in function of the domain the request would be proxied or not. Is is possible to use this format in spite of NT-domain? Thanks in advance. -- View this message in context: http://freeradius.1045715.n5.nabble.com/Credentials-format-in-Windows-supli… Sent from the FreeRadius - User mailing list archive at Nabble.com.

pairfind segmentation fault
by Juan Pablo L. 23 Jun '11

23 Jun '11

Hi, i m writing a module2 for freeradius 2.1.10 on linux 2.6.18-194.el5PAE. this is the code: vp = pairfind(request->packet->vps,PW_USER_NAME); DEBUG("Found username = %s",vp->data.strvalue); // create and add the cleartext-password vp_clear_password = pairmake("Cleartext-password","smart",T_OP_SET); pairadd(&request->config_items, vp_clear_password); // create and add the callback-id vp = pairmake("callback-id","0702005010701059",T_OP_SET); pairadd(&request->reply->vps,vp); but the pairfind is giving segmentation fault: Program received signal SIGSEGV, Segmentation fault. 0x00b2879b in authorize (instance=0x8184460, request=0x81bbc68) at ../main.c:135 135 vp = pairfind(request->packet->vps,PW_USER_NAME); I have no idea what the problem is. What is the different between pairmake and radius_paircreate ? when am i supposed to use pairfree ? please let me know what the problem is. thanks!!

2.1.x 34c68ba8: freebsd 7.x: segfault/internal error in select()
by Russell Jackson 23 Jun '11

23 Jun '11

I'm getting a segfault on exit after logging this to syslog: Exiting due to internal error: Failed in select: Invalid argument kernel: pid 87513 (radiusd), uid 133: exited on signal 11 select(2) indicates that EINVAL is returned when the timeout is invalid (being negative or too large). I modified the error message to include the value of "when" in lib/event.c. I then got: Exiting due to internal error: Failed in select: Invalid argument: wake 4sec, 1000000usec I suspected that tv_usec needs to be < USEC, so I kluged the code to subtract 1 from when.tv_usec if it's >= USEC. So far, I haven't had any more crashes. Commit d8084182 seems to be when this code was changed last, and I didn't have this problem before on 2.1.x. https://github.com/alandekok/freeradius-server/commit/d8084182bbec453712a96… -- Russell A Jackson <raj(a)csub.edu> Network Analyst California State University, Bakersfield

Returning Multiple Reply Items problem ?
by Robert Roll 22 Jun '11

22 Jun '11

I seen to have encountered a problem with returning multiple reply-item attributes ? They seem to be found, but only some arereturned... see the debug snippets below... It seems if they have the same name, only one of them gets returned ? However, for the Cisco-AVPair attributes, it is very common to need to define many of them ? Is there a way to get them all returned ? Currently running 2.1.10 .. Thanks, Robert i.e. ##### Seem to be found in Directory ##############3 [ldapADutVLANs] looking for reply items in directory...

MAC auth bypass with freeradius/openldap
by g17jimmy 22 Jun '11

22 Jun '11

I've been looking at this for a day now and it seems like I'm close, but something is not right. I have a freeradius server with an openldap backend for MAC auth bypass. This system is just for test, but it is an essential first step in my project. I'm using freeradius2-2.1.7-7.el5, freeradius2-ldap-2.1.7-7.el5, openldap-servers-2.3.43-12.el5_6.7, and I am currently using a Cisco labled linksys SFE-2000 switch. Since I have been reading docs and trying different things all day I'm thinking there is something I've just messed up on and overlooked while going over the files. I have tried creating the MAC address in LDAP several ways, as a cn(objectclass=device), as a uid(with and without a password.) Here are the files I've mod'd: ********************************** raddb/modules/ldap: ********************************** ldap { cache = no server = "localhost" identity = "uid=radauth,ou=radius,dc=CSPKRB" password = password basedn = "ou=radius,dc=CSPKRB" filter = "(cn=%{User-Name})" tls { start_tls = no } default_profile = "uid=radauth,ou=radius,dc=CSPKRB" profile_attribute = "radiusProfileDn" access_attr = "cn" dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 5 groupname_attribute = radius_users groupmembership_filter = "(|(&(objectClass=GroupOfNames)(member=%{Ldap-UserDn}))(&(objectClass=GroupOfUniqueNames)(uniquemember=%{Ldap-UserDn})))" timeout = 4 timelimit = 3 net_timeout = 1 set_auth_type = no } ********************************** raddb/site-enabed/inner-tunnel: ********************************** server inner-tunnel { authorize { preprocess ldap pap update control { Proxy-To-Realm := LOCAL } } eap { ok = return } } authenticate { Auth-Type PAP { pap } eap } session { radutmp } post-auth { Post-Auth-Type REJECT { attr_filter.access_reject } } pre-proxy { } post-proxy { eap } ********************************** clients.conf ********************************** client localhost { ipaddr = 127.0.0.1 secret = SharedSecret require_message_authenticator = no } client 192.168.0.0/16 { require_message_authenticator = no secret = SharedSecret nastype = other } ********************************** debug output: ********************************** rad_recv: Access-Request packet from host 192.168.1.254 port 49154, id=0, length=99 NAS-IP-Address = 192.168.1.254 NAS-Port-Type = Ethernet NAS-Port = 24 User-Name = "0010182b9065" Acct-Session-Id = "0500002B" EAP-Message = 0x0200001101303031303138326239303635 Message-Authenticator = 0x57f15349b978ec4c8dcdda92f6cc6fed +- entering group authorize {...} ++[preprocess] returns ok [auth_log] expand: /var/log/radius/radacct/%{Client-IP-Address}/auth-detail-%Y%m%d -> /var/log/radius/radacct/192.168.1.254/auth-detail-20110621 [auth_log] /var/log/radius/radacct/%{Client-IP-Address}/auth-detail-%Y%m%d expands to /var/log/radius/radacct/192.168.1.254/auth-detail-20110621 [auth_log] expand: %t -> Tue Jun 21 16:38:24 2011 ++[auth_log] returns ok [suffix] No '@' in User-Name = "0010182b9065", looking up realm NULL [suffix] No such realm "NULL" ++[suffix] returns noop [eap] EAP packet type response id 0 length 17 [eap] No EAP Start, assuming it's an on-going EAP conversation ++[eap] returns updated ++[unix] returns notfound ++[files] returns noop [ldap] performing user authorization for 0010182b9065 [ldap] expand: (cn=%{User-Name}) -> (cn=0010182b9065) [ldap] expand: ou=radius,dc=CSPKRB -> ou=radius,dc=CSPKRB rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in ou=radius,dc=CSPKRB, with filter (cn=0010182b9065) [ldap] checking if remote access for 0010182b9065 is allowed by cn rlm_ldap: performing search in uid=radauth,ou=radius,dc=CSPKRB, with filter (objectclass=radiusprofile) rlm_ldap: object not found [ldap] default_profile/user-profile search failed [ldap] looking for check items in directory...

rlm_exec and proxy request paradox
by Nathan M 21 Jun '11

21 Jun '11

Hello, I'm in the process of updating old 1.x freeradius servers to 2.1.10. We have scripts which fire to verify some local verifications and return some attributes which get passed along with the response to the NAS. The old method used Exec-Program-Wait in the users file; however, per recommendation in docs and list I'm converting things over to use the newer rlm_exec method. The new method works great for local authentication; however, I'm getting stumped on requests which are proxied to another radius server which accepts the request. Process of events: 1. Auth request is proxied to 3rd party server, which returns an Access-Accept rad_recv: Access-Accept packet from host 10.0.0.243 port 1645, id=184, length=37 Framed-Protocol = PPP Framed-Compression = Van-Jacobson-TCP-IP Proxy-State = 0x313238 2. As configured in post-proxy, visp_proxyauth is run. For the sake of simplicity visp_proxyauth executes a script which simply responds with exit 1 to mimic a failed local verification. # Executing section post-proxy from file /usr/local/etc/raddb/sites-enabled/default +- entering group post-proxy {...} Exec-Program output: Exec-Program: returned: 1 ++[visp_proxyauth] returns reject Found Auth-Type = Accept Auth-Type = Accept, accepting the user Problem, even though visp_proxyauth returns reject with exit 1, I believe the earlier Auth-Type = Accept from the response of the 3rd party radius server the request was proxied to is being used to accept the login. This differs from how 1.x acted in that if exec-program-wait returned exit 1 it would fail the request. My new install of 2.1.10 accepts the request which is not the desired behavior. I'm definitely open to modifying my config or exit codes to accommodate any differences introduced in 2.x. I've seemingly tried too many different configuration options and different tactics to try to make this work but seem to be stumped and looking for some outside perspective. My goal would be to ultimately reject the request if visp_proxyauth exits with return value 1 (user reject). Any assistance is greatly appreciated. - N Complete debug output follows: FreeRADIUS Version 2.1.10, for host x86_64-unknown-linux-gnu, built on Jun 15 2011 at 18:03:23 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

Multivalued (LDAP) Attributes and string matching, or regexes
by Jason Antman 21 Jun '11

21 Jun '11

Greetings, I have to control authorization based on a (possibly) multi-valued LDAP reply attribute called employeeType. I have all of the LDAP code working fine, but seem to have hit a snag. Each user has 1 to ??? (usually a max of 5 or so) employeeType values. The pertinent ones include "STAFF", "STAFF TEMPORARY", "STAFF OFFSITE", and "STAFF RETIRED". I need to allow all "STAFF" types access, unless their one and only "STAFF*" is "STAFF RETIRED" (yes, don't get me started, but it's considered "perfectly valid" for someone to have employeeTypes of staff, staff retired, and staff offsite). So essentially, I need to allow in anyone with "STAFF", not followed by " RETIRED". At the moment, I'm using %{reply:employeeType[*]} which works fine for reged matching all of the other funky attributes that should grant access. But I can't seem to figure out how to say, either with unlang comparisons or regexes (I'm on CentOS/RedHat, so I assume it would be POSIX, either BRE or ERE) or both, how to exclude that one condition. Examples: STAFF, STAFF RETIRED, SALARIED -> Accept STAFF -> Accept STAFF RETIRED -> Reject STAFF, STAFF TEMPORARY -> Accept FOO, STAFF RETIRED, BAR -> Reject FOO, STAFF, BAR -> Accept Any hints or guidance would be greatly appreciated. I've searched through all of the regex material I could find, and asked on #regex IRC and as many regex gurus as I could find, and the best answer I got was to combine regexes with some sort of unlang construct... but I can't seem to think of anything which will match my logical need... "the string STAFF not followed immediately by the string RETIRED". Thanks, Jason Antman PS - I know the Right answer here is "fix your LDAP schema". Unfortunately, I don't have any control over that. Or even the power to make suggestions. All I have is a directive of who gets in and who doesn't.

chain two authentication modules together
by madmatrix 20 Jun '11

20 Jun '11

Hi All, I searched some related posts in the forum and see Alan pointed out the rlm_example.c has the example for chaining two authentication modules. I have 2.1.10 version source code. In the rlm_example.c, the authentication part is only like this: static int example_authenticate(void *instance, REQUEST *request) { /* quiet the compiler */ instance = instance; request = request; return RLM_MODULE_OK; } Can't see how two authentication modules get chained here. What I'm wanting to do is integrate LDAP and OTP. The OTP I want to use doesn't have interface to radius. So I'm planning to get that OTP source code into a new FR module. For LDAP part, I just want to include the existing module to the new one. Is this doable? I guess I may need implant the LDAP module code into the new module too. The whole authentication process is: 1. LDAP authentication. 2. If successful, do something and request 2nd OTP authencation. If not, reject the authentication. >From what I read here, the new module must be the way to do this. But is there any easy way to integrate existing module like LDAP into the new module? Thanks a lot for your help. Really appreciate it.
