Fwd: Issue on receiving searchResEntry message from AD server
by Adarsha S 06 Oct '14

06 Oct '14

Hi All, I'm using freeradius-server-2.1.12.[ though its bit old version]. I've made a setup with my linux machine to work as radius server[ free radius is installed here]. For user LDAP authentication I'm using Windows 2003 server. My LDAP search works fine on receiving searchResDone from AD server.User authentication works fine. But on receiving searchResEntry message from AD server, My radius clients doesn't do anything and after few seconds the unbindRequest is Sent from radius client. I've attached the packet capture. Please guide me to fix this issue other than upgrading the free radius server as its no feasible for me at this moment. Thanks, Adarsha

New in 3.0.5: updated expressions
by Alan DeKok 06 Oct '14

06 Oct '14

The "expr" module has been updated in the v3.0.x branch, which will become 3.0.5. The old version did not respect operator precedence. It just evaluated the string left to right. This forced people to use (...) to get the correct results. The new code implements precedence properly. As a bonus, it now supports bit shifts: 1 << 3 == 8 This is a minor feature which will make it easier to create simple policies. Alan DeKok.

Re: Beginner help

Hi, I have installed Freeradius version 3 and get openssl error as my openssl version was in range 1.0.1 - 1.0.1f*. * Now I removed my older openssl version and installed openssl 1.0.1g. Edited radiusd.conf file as well. allow_vulnerable_openssl = 'CVE-2014-0160' When I start freeradius server ( ./radiusd -X for debug mode), it will refuse to start with libssl version which is currently installed on your server. Root cause for this is “Security advisory CVE-2014-0160 (Heartbleed)” I rechecked my openssl version that I have installed. It is 1.0.1g and freeradius is 3.0.3. Please help me in this regard. What am I missing here? Thanks, Kavya

Re: Per Proxy Server Statistics

Hi, I want to track proxy server statistics like minimum response time, maximum response time, Average response time, Mean response time. I don't think the freeradius currently provides these statistics. Now, since I want these statistics, can somebody guide & help me to achieve these statistics using freeradius.

Acct-Delay-Time attribute in buffered-sql server mode
by Rygl Aleš 05 Oct '14

05 Oct '14

Hi all, I have found an interesting issue related to Acct-Delay-Time attribute when buffered-sql mode is in use. I am not sure if it is a bug or feature. IMHO it is a bug but I would like to discuss it here. I am using freeradius for accounting in buffered-sql mode with MySQL backend. The main radacct table is using memory engine so it is pretty fast nevertheless the buffered-sql mode is a must. We have more 1.000 Acct req/sec in average with additional repeated peaks. We need to store the Acct-Delay- Time for diagnostic purposes. It is not always present in the Accounting request from NAS but if it is there it indicates that NAS is experiencing some performance problems. And the issue is that even if there is no Acct-Delay-Time received from the NAS, it appears in radacct table then and from my observations it has nothing to do with the real delay of the session start and indicates just the amount of time for which the record was waiting in radacct/detail.work file. IMHO this is wrong because the SQL scripts in dialup.conf are doing a correction of session start time based using Acct-Delay-Time. My accounting-start-query: accounting_start_query = "INSERT into ${acct_table1} (AcctUpdateTime, AcctSessionId, AcctUniqueId, UserName, NASIPAddress, AcctStartTime, AcctSessionTime, AcctAuthentic, AcctInputOctets, AcctOutputOctets, CalledStationId, CallingStationId, AcctTerminateCause, FramedIPAddress, AcctStartDelay, AcctStopDelay, SgsnIpAddr, Imsi, 3GPPSelectionMode, 3GPPGPRSNegotiatedQoSProfile, Acct_Status_Type, 3GPPChargingId, 3GPPNSAPI, 3GPPSGSNMNCMCC, 3GPPRATType, 3GPPUserLocationInfo, 3GPPMSTimezone, 3GPPIMEISV, TMOChargingRuleBaseName, SNVirtualAPNName, SNRulebase) values('%S', '%{Acct- Session-Id}', '%{Acct-Unique-Session-Id}', '%{SQL-User-Name}', '%{NAS-IP- Address}', DATE_SUB('%S', INTERVAL %{Acct-Delay-Time:-0} SECOND), '0', '%{Acct-Authentic}', '0', '0', '%{Called-Station-Id}', '%{Calling-Station- Id}', '', '%{Framed-IP-Address}', '%{Acct-Delay-Time}', '0','%{3GPP-SGSN- Address}','%{3GPP-IMSI}','%{3GPP-Selection-Mode}','%{3GPP-GPRS-Negotiated-QoS- profile}','%{Acct-Status-Type}','%{3GPP-Charging-ID}','%{3GPP-NSAPI}','%{3GPP- SGSN-MCC-MNC}','%{3GPP-RAT-Type}','%{3GPP-Location-Info}','%{3GPP-MS-Time- Zone}','%{3GPP-IMEISV}','%{TMO-Charging-Rule-Base-Name}','%{SN-Virtual-APN- Name}','%{SN-Rulebase}')" I always thought buffered-sql server is just a loader of the detail file to db. But it looks like it is working as a real radius server manipulating the Acct-Delay-Time attribute which is IMHO wrong here and should be suppressed somehow. What is your opinion? I am running Debian 7.2, freeradius 2.1.12, kernel 3.2.0-4-amd64 Regards Ales

Discarding Duplicate Request
by Rando Nakarmi 04 Oct '14

04 Oct '14

I been seeing quite a large number of message like below logged in radius.log lately. Discarding duplicate request from client classroom98 port 32880 - ID: 131 due to unfinished request 241848 I read some thread, this might be the case when back-end server (i.e auth servers) are too slow to respond. My back-end is AD, using ntlm_auth. radius version 2.1.12-4 samba version 3.5.8-68 Any hints or suggestion how to resolve this would be very helpful. Most of the users get authenticated ( I don't think ntlm_auth is responding slow), I could not figure this out --cheers, Rando

disable zombie period and status checks
by Travis Dimmig 03 Oct '14

03 Oct '14

I have FreeRADIUS acting as a proxy server in an environment with a temperamental ACS server as the home server. The ACS server is known to be unreliable, an NPS server is being staged to replace it. In the meantime, however, I have to work as well as I can with the ACS server, and have no access or control to modify it. The ACS server regularly does not respond to requests, initiating the zombie period. It just as regularly doesn't respond to the status checks (I'm using auth request type checks to ensure compatibility). The requirement of 3 successful responses in a row to be marked alive again is difficult to meet with this server. I realize of course that the best solution is to fix the home server, but while that is being worked on I need my FreeRADIUS server to try to proxy requests as much as possible. I have dug through the configs, but found no way to completely disable the zombie period and status check behavior of the server. My goal is for FreeRADIUS to always consider the home server alive and proxy all requests to it, regardless of the fact that some do not get responses. Is this possible? Thanks, Travis Dimmig

checkItem not being checked
by Victor Tarhon-Onu 03 Oct '14

03 Oct '14

Hello Everyone, Before proceeding further I'm going to describe shortly what I want to do and what I did so far. Initially the requirement was to pull some authentication data from an LDAP server so that we can make some custom equipments to authenticate those LDAP users. These equipments can use only radius for authentication. This works just fine. Later the requirement was changed and I was asked to do some privilege separation based on the group each LDAP user is in. So it seemed to be easier just to map the LDAP gidNumber entry for each user to a radius check item: /etc/raddb/ldap.attrmap:checkItem Group-ID gidNumber /etc/raddb/dictionary:ATTRIBUTE Group-ID 3000 integer So in /etc/raddb/users I added something like DEFAULT Auth-Type = LDAP Service-Type = Login, Fall-Through = Yes DEFAULT Group-ID == 100 Service-Type := Shell-User DEFAULT Group-ID == 101 Service-Type := Dialout-Framed-User The problem is that the Service-Type never changes because the Group-ID doesn't match any of those checks. It remains set to the value (Login) I've set as default at the beginning of the file. However, when running the radius server in debug mode, I can see that the Group-ID is set correctly for each authenticated user: rlm_ldap: Adding gidNumber as Group-ID, value 100 & op=21 ...but I'm not sure if it's exported (or even supposed to be) out from rlm_ldap. The freeradius version is 1.1.3 (freeradius-1.1.3-1.6.el5). I am inserting below the entire output of the radius server during an authentication/authorization attempt: rad_recv: Access-Request packet from host 127.0.0.1:44291, id=235, length=57 User-Name = "testuser" User-Password = "testpassword" NAS-IP-Address = 255.255.255.255 NAS-Port = 0 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 0 modcall[authorize]: module "preprocess" returns ok for request 0 modcall[authorize]: module "chap" returns noop for request 0 modcall[authorize]: module "mschap" returns noop for request 0 rlm_realm: No '@' in User-Name = "testuser", looking up realm NULL rlm_realm: No such realm "NULL" modcall[authorize]: module "suffix" returns noop for request 0 rlm_eap: No EAP-Message, not doing EAP modcall[authorize]: module "eap" returns noop for request 0 users: Matched entry DEFAULT at line 6 modcall[authorize]: module "files" returns ok for request 0 modcall: entering group redundant for request 0 rlm_ldap: - authorize rlm_ldap: performing user authorization for testuser radius_xlat: '(&(objectClass=posixAccount)(uid=testuser))' radius_xlat: 'dc=mydomain,dc=com' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: attempting LDAP reconnection rlm_ldap: (re)connect to ldapserver.mydomain.com:389, authentication 0 rlm_ldap: setting TLS CACert File to /usr/share/ssl/certs/mydomain-CA.crt rlm_ldap: setting TLS CACert Directory to /usr/share/ssl/certs/ rlm_ldap: starting TLS request done: ld 0xb8b6c708 msgid 1 rlm_ldap: bind as / to ldapserver.mydomain.com:389 rlm_ldap: waiting for bind result ... request done: ld 0xb8b6c708 msgid 2 rlm_ldap: Bind was successful rlm_ldap: performing search in dc=mydomain,dc=com, with filter (&(objectClass=posixAccount)(uid=testuser)) request done: ld 0xb8b6c708 msgid 3 rlm_ldap: looking for check items in directory... rlm_ldap: Adding gidNumber as Group-ID, value 504 & op=21 rlm_ldap: looking for reply items in directory... rlm_ldap: user testuser authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap1" returns ok for request 0 modcall: leaving group redundant (returns ok) for request 0 modcall: leaving group authorize (returns ok) for request 0 rad_check_password: Found Auth-Type LDAP auth: type "LDAP" Processing the authenticate section of radiusd.conf modcall: entering group LDAP for request 0 modcall: entering group redundant for request 0 rlm_ldap: - authenticate rlm_ldap: login attempt by "testuser" with password "testpassword" rlm_ldap: user DN: uid=testuser,ou=People,dc=mydomain,dc=com rlm_ldap: (re)connect to ldapserver.mydomain.com:389, authentication 1 rlm_ldap: setting TLS CACert File to /usr/share/ssl/certs/mydomain-CA.crt rlm_ldap: setting TLS CACert Directory to /usr/share/ssl/certs/ rlm_ldap: starting TLS request done: ld 0xb8befaa8 msgid 1 rlm_ldap: bind as uid=testuser,ou=People,dc=mydomain,dc=com/testpassword to ldapserver.mydomain.com:389 rlm_ldap: waiting for bind result ... request done: ld 0xb8befaa8 msgid 2 rlm_ldap: Bind was successful rlm_ldap: user testuser authenticated succesfully modcall[authenticate]: module "ldap1" returns ok for request 0 modcall: leaving group redundant (returns ok) for request 0 modcall: leaving group LDAP (returns ok) for request 0 Login OK: [testuser] (from client localhost port 0) Sending Access-Accept of id 235 to 127.0.0.1 port 44291 Service-Type = Login-User Finished request 0 --
