Determining which module caused a reject
by Jack Smith 15 Apr '09

15 Apr '09

Hi I am running freeradius 2.1.4. Alan has mentioned that unlang logic should be restricted to Post-Auth (afterall, that is what it is there for). In order for me to do this, I need to know in the Post-Auth-Type REJECT which module caused the reject. Currently, I can do this in the authentication section quite easily: authenticate { Auth-Type PAP { pap { ok = return reject = 1 } if (reject) { update reply { Reply-Message := "Incorrect password for %{User-Name}" } } } Auth-Type CHAP { chap { ok = return reject = 1 } if (reject) { update reply { Reply-Message := "Incorrect password for %{User-Name}" } } } } But as I said, I would like to move this logic to the Post-Auth-Type Reject. It is not only Auth-Type PAP or CHAP which can cause a reject, my SQL module can also cause a reject. Hence I cannot use the following logic (lets assume we used PAP authentication) in the Post-Auth-Type REJECT: Post-Auth-Type REJECT { if (pap) { } } The reason why I cannot use the above is because in the scenario when a user is successfully authenticated using PAP, but the SQL module rejects him (lets say due to lack of credit), the above if statement will evaluate to true. To summarise once again: How can I obtain which module caused the reject in the Post-Auth-Type REJECT? Thanks in advance

Re: Re: rlm_perl behavior

Hello, I just subscribed so I won't be able to quote properly but I hope at least the message is associated with the right thread (I found it on the web archive of the mailing list). I've been using FreeRADIUS for about 4 year now and it is a wonderful product - there's no question why you're No 1! For the past years of using and developing rlm_perl modules for FreeRADIUS, I've only been astonished and happy because of the new functionalities etc that the development team have been adding to the new releases. This all ended with this crippling of the rlm_perl module in the new 2.1.4 release (btw I downloaded and compiled from source the 2.1.4 release under CentOS 5.2, but radiusd - v says that the version is 2.1.5...). Here are my thoughts on the matter and quotes of the discussion for clarity: > Apostolos Pantsiopoulos wrote: >> I noticed that the following directives : > ... >> for perl were not present in the file after the compiling. >> >> Are these directives obsolete? > > Yes. The server already has a thread management system. Adding > another one for Perl is unnecessary. Removing something which has been working fine (the rlm_perl thread management system) is not a good thing IMHO. It helped me achieve more flexibility and was really powerful. > Apostolos Pantsiopoulos wrote: > > Does this mean that in the new behavior I have one perl instance > > (thread) shared by all the radius threads?

Having only one perl instance will have very bad influence on performance in large integrations. I've experienced what happens in this case - the CPU usage of radiusd is very low (<1%) but requests are waiting each other to finish. This causes huge delays (I've seen 2-3 minutes!) and flooding the NAS's logs with RADIUS Server DEAD... RADIUS Server Alive messages. I've been happily using multiple perl instances to achieve the functionality that I need (like Apostolos Pantsiopoulos) for years now. In my case, I created several rlm_perl instances, each loading different perl applications to take care of different cases depending on the NAS-IP like this: perl instance1 { # This is a large branch => I put higher values for max_clones, start_clones etc but keeping the pool static to avoid reloading the settings from the DB on module instantiation } perl instance2 { # This is another (slightly modified) script which takes care of special circumstances } # ... and now using the wonderful ulang functionality I do the following in ... say accounting switch "%{NAS-IP-Address}" { case '10.250.15.1' { instance1 } case '10.250.17.192' { instance2 } } As far as I could understand from my brief research with google and reading the mailing list, achieving this is now impossible. And I discover this amidst integration. Correct me if I'm wrong, but I'm left with the impression that doing such configurations now requires modifying the rlm_perl's code etc which is not an option. This leaves me with the options to downgrade the FreeRADIUS version or shoot myself in the head ;-). Anyways IMHO this 2.1.4 release is a huge step back. I certainly don't want to insult anyone but why remove functionality which has been working fine for years forcing people rewrite their code (amidst started integrations and projects) to support the new versions limitations! P.S.: Sorry for sending the previous unfinished message, I pressed the wrong key combination

About sqlippool
by Tseveendorj 15 Apr '09

15 Apr '09

Hello, Sorry for ask newbie question. I would like to implement sqlippool functionality on FreeRADIUS 2.1.3. I read /usr/local/share/doc/freeradius/rlm_sqlippool there has following note "IP-Pool Attribute (Keep in mind that its a **CHECK** item, not reply)" I didn't understand. which attribute (IP-Pool or Pool-Name) needed for sqlippool? and I also defined sqlippool in accounting { ...} and post-auth {...} directive. But pool didn't work. You can see more detailed below. Thanks for any help. accounting { # # Create a 'detail'ed log of the packets. # Note that accounting requests which are proxied # are also logged in the detail file. detail # daily # Update the wtmp file # # If you don't use "radlast", you can delete this line. #unix # # Log traffic to an SQL database. # # See "Accounting queries" in sql.conf sql *sqlippool* # # For Simultaneous-Use tracking. # # Due to packet losses in the network, the data here # may be incorrect. There is little we can do about it. radutmp # sradutmp # Return an address to the IP Pool when we see a stop record. # main_pool # # Instead of sending the query to the SQL server, # write it into a log file. # # sql_log # Cisco VoIP specific bulk accounting # pgsql-voip # Filter attributes from the accounting response. attr_filter.accounting_response # # See "Autz-Type Status-Server" for how this works. # # Acct-Type Status-Server { # # } } and post-auth { # Get an address from the IP Pool. # main_pool # # If you want to have a log of authentication replies, # un-comment the following line, and the 'detail reply_log' # section, above. # reply_log # # After authenticating the user, do another SQL query. # # See "Authentication Logging Queries" in sql.conf sql * sqlippool* # # Instead of sending the query to the SQL server, # write it into a log file. # # sql_log # # Un-comment the following if you have set # 'edir_account_policy_check = yes' in the ldap module sub-section of # the 'modules' section. # # ldap exec # # Access-Reject packets are sent through the REJECT sub-section of the # post-auth section. # # Add the ldap module name (or instance) if you have set # 'edir_account_policy_check = yes' in the ldap module configuration # Post-Auth-Type REJECT { attr_filter.access_reject } }

Due to a HD loss, bugs.freeradius.org is down, and won't be coming back. Unfortunately, this means a loss of patches, reports, user accounts, etc. Before we put another bug system online, we would like to ask for your input. Which bug reporting system do you use? Which one do you prefer? Which ones are horrible, and shouldn't be considered? Alan DeKok.

3Com 3226 .1X to freeradius fails
by john 14 Apr '09

14 Apr '09

Hello all, I am trying to connect a Windows XP/sp2 machine to my network using a 3com 3226 superstack switch as a NAS. This windows Client can successfully authenticate via an wireless access point when using WPA2/AES via PEAP/mschap2. However when I plug the same client into my 3com 3226 switch configured for .1X I am unable to authenticate. The supplicant interface is the only wired interface on this laptop, is configured for PEAP, I am not trying to use a certificate at this point, Auth type is EAP-MSCHAPV2, and automatically user windows logon is ticked. Running wireshark on the XP box shows no radius traffic but a series of EAP messages that go like this: EAP failure from NAS EAP Request message from NAS EAP Response from supplicant EAP Request from NAS EAP Response from Supplicant EAP failure from NAS EAP Request from NAS EAP Response from supplicant EAP request, PEAP [Palekar] from NAS Client hello, SSL from supplicant Then nothing else... I hope someone can help me figure this out. Thanks!

eap issues
by Craig White 14 Apr '09

14 Apr '09

Trying both TLS and TTLS on Macintosh OS X 10.5.5 certificates seem to be fine on both Windows and Macintosh using the ca.der and caclient.p12 (using Ivan's newer script for generating) for TLS Below is radiusd -X log with one failed attempt and it just seems as if the eap challenges go out but responses never come back. LDAP authorizes and authenticates my VPN connections fine, it's just 802.1x that is my problem.

LDAP with fallback on local authentication?
by Justin Steward 13 Apr '09

13 Apr '09

Hi guys, I'm sure these are questions that have been asked a thousand times, but can't for the life of me find the answers I'm looking for. My first problem is this: I want to store reply attributes for my users in a MySQL database, however I want them to authenticate against an LDAP server. No problem, I sort of have this working. Except the reply attributes get sent even on an Access-Reject packet. This seems undesirable to me. My second problem is this: The LDAP server isn't necessarily in the same building as the radius server. I want users to be able to fall back on locally stored passwords in the MySQL database should the LDAP server be down for some reason. I'd thought that setting Fall-Through=yes and having a DEFAULT Auth-Type = local would have done this, but no dice. Any suggestions? Regards, Justin
