Spoofed Reply Message on Proxy Request from FreeRADIUS Server
by Steinhagen, Tom 04 May '15

04 May '15

I am attempting to set up RADIUS proxy to a McAfee (nee NordicEdge) One-time Password server. Any assistance would be appreciated. This is new installation, and I am new to FreeRADIUS. In command-line testing, debug shows the message "Ignoring spoofed proxy reply. Signature is invalid." Testing command: 'radtest -t pap -x tsteinhagen "<PASSWORD>" 127.0.0.1 1812 testing123' PAP is a limitation of the McAfee product. Debug output below.

multiple fields from rlm_mysql?
by Jorge Pereira 04 May '15

04 May '15

Hi, I would like to know if have some way to do the below example in a single query. something like a tuple/foreach or otherwise way. my current solution is: My-AVP-A = "%{sql: SELECT field_a FROM tb_my WHERE field_a = '%{Value_A}'}" My-AVP-B = "%{sql: SELECT field_b FROM tb_my WHERE field_b = '%{Value_B}'}" My-AVP-C = "%{sql: SELECT field_c FROM tb_my WHERE field_c = '%{Value_C}'}" My-AVP-D = "%{sql: SELECT field_d FROM tb_my WHERE field_d = '%{Value_D}'}" the problem it's because i would like to avoid multiple queries. -- Jorge Pereira

ldapi:// with SASL/EXTERNAL
by Michael Ströder 02 May '15

02 May '15

HI! My FreeRADIUS 3.0.8 server works with OpenLDAP also with ldapi:// and simple bind. But it does not work with SASL/EXTERNAL bind (see relevant -X output attached below). A short test as the correct demon user 'radiusd' with ldapwhoami -H ldapi:// -Y EXTERNAL returns the expected and correct authz-DN. But if FreeRADIUS starts OpenLDAP logs look strange: 2015-05-02T00:28:03.170556+02:00 srv3 slapd[1350]: conn=1344 fd=18 ACCEPT from PATH=/run/slapd/ldapi (PATH=/run/slapd/ldapi) 2015-05-02T00:28:03.172464+02:00 srv3 slapd[1350]: conn=1344 op=0 BIND dn="" method=163 2015-05-02T00:28:03.173796+02:00 srv3 slapd[1350]: conn=1344 op=0 RESULT tag=97 err=14 text=SASL(0): successful result: 2015-05-02T00:28:03.179488+02:00 srv3 slapd[1350]: connection_operation: error: SASL bind in progress (tag=66). 2015-05-02T00:28:03.179758+02:00 srv3 slapd[1350]: conn=1344 op=1 RESULT tag=48 err=1 text=SASL bind in progress 2015-05-02T00:28:03.180154+02:00 srv3 slapd[1350]: conn=1344 fd=18 closed Ciao, Michael. --------------------------- snip --------------------------- # Loaded module rlm_ldap # Instantiating module "ldap" from file /etc/raddb/mods-enabled/ldap ldap { server = "ldapi://" sasl_mech = "EXTERNAL" user { scope = "sub" access_positive = yes } group { filter = "(objectClass=posixGroup)" scope = "sub" name_attribute = "cn" membership_attribute = "memberOf" membership_filter = "(member=%{control:Ldap-UserDn})" cacheable_name = no cacheable_dn = no } client { filter = "(objectClass=radiusClient)" scope = "sub" base_dn = "${..base_dn}" } profile { } options { ldap_debug = 40 chase_referrals = no rebind = yes net_timeout = 1 res_timeout = 20 srv_timelimit = 20 idle = 60 probes = 3 interval = 3 } tls { start_tls = no } } rlm_ldap: libldap vendor: OpenLDAP, version: 20440 accounting { reference = "%{tolower:type.%{Acct-Status-Type}}" } post-auth { reference = "." } rlm_ldap (ldap): Initialising connection pool pool { start = 5 min = 4 max = 6 spare = 3 uses = 0 lifetime = 0 cleanup_interval = 30 idle_timeout = 60 retry_delay = 1 spread = no } WARNING: Ignoring "spare = 3", forcing to "spare = 2" rlm_ldap (ldap): Opening additional connection (0), 1 of 6 pending slots used rlm_ldap (ldap): Connecting to ldapi:// rlm_ldap (ldap): Waiting for bind result... rlm_ldap (ldap): Bind with (anonymous) to ldapi:// failed: SASL bind in progress rlm_ldap (ldap): Server said: SASL(0): successful result: . rlm_ldap (ldap): Opening connection failed (0) rlm_ldap (ldap): Removing connection pool /etc/raddb/mods-enabled/ldap[8]: Instantiation failed for module "ldap"

3.0.3 Segmentation fault (core dumped)
by Mohamed Lrhazi 01 May '15

01 May '15

Hello, Running 3.0.3... from ppa:freeradius/stable-3.0 /usr/sbin/freeradius -v freeradius: FreeRADIUS Version 3.0.3, for host x86_64-pc-linux-gnu, built on May 20 2014 at 11:59:21 Am running four instances (in docker containers) on two VMs... behind a load balancer. After running for a couple hundred hours, instances start hitting seg faults... restarting the instances gets them going again for few hundred hours... How would you debug this in production settings? should I upgrade to newer version first? Thanks, Mohamed.

Hi, You where told the solution, and you chose to ignore it, and then ask why. The make deb makes the necessary changes to conform to the Debian environment. Debian has it´s own rules. Plus, installing from debs has other niceties like besides tracking things and being capable of uninstalling, also allows you to upgrade and not think much about losing the current config.

FR 3.0.7 RADIUS Client Schema error
by Ben Humpert 30 Apr '15

30 Apr '15

Hi, in the schema file the entry for require message authenticator is listed as olcAttributeTypes: ( 1.3.6.1.4.1.11344.1.100.2.6 NAME 'radiusClientRequireMa' SINGLE-VALUE DESC 'Require Message Authenticator' EQUALITY booleanMatch SYNTAX '1.3.6.1.4.1.1466.115.121.1.7' ) thus one has to enter TRUE or FALSE in LDAP - everything else (I tried it with true, Yes, yes, YES and 1) throws an LDAP error. But now, with TRUE FR won't start anymore. Below is the debug log ....

Thanks

dynamic expansion will not be dynamically expanded in ldap configuration
by Angel L. Mateo 30 Apr '15

30 Apr '15

Hello, I'm trying to configure ldap module for freeradius. For group membership I have this configuration: membership_filter = "(&(uid=%{User-Name})(objectClass=posixAccount))" but whenever I start freeradius, I get the error /etc/freeradius/mods-enabled/ldap[176]: Found dynamic expansion in string which will not be dynamically expanded where the membership_filter option is at line 176 of the ldap file. And when I user logins, there is no group search in the ldap, only a search to find the user. What am I doing wrong? -- Angel L.
