Hy :-) I am interested to know about success stories of people using FreeRadius in a production environment. I have read http://www.freeradius.org/testimonials.html but I would like to obtain a few more experiences.

Ignore the authentication request
by ALMEIDA Antonio Jose 23 Jan '06

23 Jan '06

It's possible to ignore the authentication request instead to answering with reject if the user doesn't exist? I'm using the freeradius to authenticate users in a cisco vpn concentrator and I need to have some users in the vpn internal database but I can only use the internal database if the radius server is down.

Radius can't connect to LDAP
by Tim_Crouch＠uttyler.edu 23 Jan '06

23 Jan '06

We are running FreeRADIUS v. 1.0.2 2x load-balanced LDAP servers - Sun ONE DS 5.2 on W2k3 Ent. with network load balancing. One of the LDAPs is the primary and is handling the auth traffic. Here is the issue we're seeing: Approximately 10-20 times per day users are unable to authenticate - despite using correct credentials. The radius server reports bind failed because it "Can't contact LDAP server" The LDAP logs show the bind, search, and reply for the "does this user exist" request. Sometimes this search is repeated a couple of times. However, there is no follow-up bind as this user for checking the creds. If the user tries again in 30secs or more, they succeed - with the same creds as before. Any ideas? Thanks for any help! Below are excerpts from the logs: ------------------------ Radius log entry ------------------------ rlm_ldap: - authorize rlm_ldap: performing user authorization for someuser radius_xlat: '(uid=someuser)' radius_xlat: 'ou=people,dc=uttyler,dc=edu' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in ou=people,dc=uttyler,dc=edu, with filter (uid=someuser) rlm_ldap: ldap_search() failed: LDAP connection lost. rlm_ldap: Attempting reconnect rlm_ldap: attempting LDAP reconnection rlm_ldap: closing existing LDAP connection rlm_ldap: (re)connect to ldap.uttyler.edu:389, authentication 0 rlm_ldap: bind as uid=radiususer,ou=special users,dc=uttyler,dc=edu/radius_password to ldap.uttyler.edu:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful rlm_ldap: performing search in ou=people,dc=uttyler,dc=edu, with filter (uid=someuser) rlm_ldap: looking for check items in directory... rlm_ldap: looking for reply items in directory... rlm_ldap: user someuser authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns ok for request 987 modcall: group authorize returns ok for request 987 rad_check_password: Found Auth-Type LDAP auth: type "LDAP" Processing the authenticate section of radiusd.conf modcall: entering group Auth-Type for request 987 rlm_ldap: - authenticate rlm_ldap: login attempt by "someuser" with password "04191987" rlm_ldap: user DN: uid=someuser,ou=People,dc=uttyler,dc=edu rlm_ldap: (re)connect to ldap.uttyler.edu:389, authentication 1 rlm_ldap: bind as uid=someuser,ou=People,dc=uttyler,dc=edu/04191987 to ldap.uttyler.edu:389 rlm_ldap: uid=someuser,ou=People,dc=uttyler,dc=edu bind to ldap.uttyler.edu:389 failed: Can't contact LDAP server rlm_ldap: ldap_connect() failed modcall[authenticate]: module "ldap" returns fail for request 987 modcall: group Auth-Type returns fail for request 987 auth: Failed to validate the user.

Firstly, "Password" is a configure item and should really be set with := uncondtionally. Secondly, you're setting Auth-Type with := which overwrites whatever is there, which is probably why MS-CHAP isn't working (Local will be overwriting it) Assuming you have the server otherwise setup with the defaults, which have mschap BEFORE files in authorize, this will work: user Auth-Type = Local, Password := "password" Because (in the default config) mschap runs before files, therefore Auth-Type will already be set to MS-CHAP and the "=" won't overwrite it, but will set it if it's otherwise unset. - List info/subscribe/unsubscribe?

MS-CHAP and Local Authentication
by ALMEIDA Antonio Jose 23 Jan '06

23 Jan '06

Hello, Can someone tell me how can I configure the users file (with the default configuration - I'm just starting to use freeradius) to permit the same user to be authenticated by MS-CHAP and Local? Now I have something link this: User1 Auth-Type := Local, Password == "password" User2 Auth-Type := MS-CHAP, Password == " password " I need to make User1 and User2 the same. Antonio

Fallback Auth if forwarding fails
by Freeradius Users Mailing List 22 Jan '06

22 Jan '06

Hi, first of all: thanks for this great software! I would like to mainly do a radius forwarding through Proxy-To-Realm functionality. This works well. But for a short period of time I need to have a fallback strategy if forwarding fails (remote RADIUS server is dead). Is there a way to match on a different entry i.e. in the users file after recognizing that the remote RADIUS server is dead? Thanks a lot for help :-)

rlm_sqlcounter question
by Hekuran Doli 21 Jan '06

21 Jan '06

Hello, Im trying to use rlm_sqlcounter to make daily session limit, I use Max-Daily-Session := 60 to end the session in 60 seconds and finish the authentication for that day, but it dosent seems to work, it sets the Session-Timeout = 60 but the user is able to authenticate again in the same day. Also the Max-Monthly-Session dosent work but Max-All-Session work fine. Here are logs of rlm_sqlcounter in debugg mode: rlm_sqlcounter: Entering module authorize code rlm_sqlcounter: Could not find Check item value pair modcall[authorize]: module "noresetcounter" returns noop for request 0 rlm_sqlcounter: Entering module authorize code sqlcounter_expand: 'SELECT SUM(AcctSessionTime - GREATEST((1137711600 - UNIX_TIMESTAMP(AcctStartTime)), 0)) FROM radacct WHERE UserName='%{User-Name}' AND UNIX_TIMESTAMP(AcctStartTime) + AcctSessionTime > '1137711600'' radius_xlat: 'SELECT SUM(AcctSessionTime - GREATEST((1137711600 - UNIX_TIMESTAMP(AcctStartTime)), 0)) FROM radacct WHERE UserName='florin' AND UNIX_TIMESTAMP(AcctStartTime) + AcctSessionTime > '1137711600'' sqlcounter_expand: '%{sqlcca3:SELECT SUM(AcctSessionTime - GREATEST((1137711600 - UNIX_TIMESTAMP(AcctStartTime)), 0)) FROM radacct WHERE UserName='florin' AND UNIX_TIMESTAMP(AcctStartTime) + AcctSessionTime > '1137711600'}' radius_xlat: '' rlm_sqlcounter: (Check item - counter) is greater than zero rlm_sqlcounter: Authorized user florin, check_item=60, counter=0 rlm_sqlcounter: Sent Reply-Item for user florin, Type=Session-Timeout, value=60 modcall[authorize]: module "dailycounter" returns ok for request 0 rlm_sqlcounter: Entering module authorize code rlm_sqlcounter: Could not find Check item value pair Thanks
