Adding modified libraries without recompiling entirely FreeRADIUS
by yoann Couble 12 Apr '13

12 Apr '13

Hi everyone, I have a freeRADIUS 2.0.4 server which has been running well for the past two years. I am trying to integrate smoothly a modified version of the chap module. To do that I've been testing different approach on a VM for tests. With the sources downloaded from packages.debian.org, I wrote my version of rlm_chap.c. Everything compiles and works fine when i do: ./configure make make install from the source folder and run it with *radiusd*. NB: To avoid lib conflicts i remove the libs generated in /usr/local/lib during installation before i start again /usr/sbin/freeradius But now i would like to update my working version of freeradius (which was installed through an apt-get install) without causing much trouble. As I only modified rlm_chap.c I thought i could simply replace the current library /usr/lib/rlm_chap-2.0.4.so with the one produced during compilation freeradius-2.0.4/src/modules/rlm_chap/.libs/rlm_chap-2.0.4.so After that i restart freeradius (the apt-get version) with freeradius -X Everything looks fine but when i send a request i get a segmentation fault when the server tries to enter chap module. (see the debug entry further) If i go back and replace /usr/lib/freeradius/rlm_chap-2.0.4.so by the original Everything works fine again. I am pretty sure it has something to do with compilation and the way files were generated. Do you think it is possible to do what I want? i.e. inserting a modified library into the working set of library. Reinstalling the working freeradius or using the compiled files is not an possibility. If you have any idea on what I am doing wrong (I am still a beginner and I probably do a lot of things wrong), please feel free to tell me and to share with me if you had similar situations. Thanks !

Question about differences between possibilities of authentication
by Bas Penris 12 Apr '13

12 Apr '13

Hi All, The last week I've had my first encounter with FreeRADIUS as we were supposed to deploy eduroam. I had a lot of fun doing it although I have dreamt about the config files after a couple of days :) Everything is working as it should so no worries there, but I'm curious about something. I configured the proxies and the local realm. When I did a radtest like this: radtest cheese(a)localdomain.nl password 127.0.0.1 1 secret I would get an Accept-Accept. The debug output would show that first a bind and then an LDAP search is performed in our eDirectory. Okay! Fun times I thought, let's try it on my mobile phone because a test account I got from an academic institution in the UK worked so local authentication should work as well! I entered the credentials but now comes the difference. Using a Wifi device made the LDAP search fail because it tried to authenticate the user(a)domain.nl in stead of stripping the suffix. I've been staring at the config files to see if I got the LDAP-filter defined two times somewhere but that doesn't seem to be the case. Now, this wasn't a really big problem because users can be pretty stupid and we decided to let them authenticate using their email address in stead of their username@domain which would to too much confusion for them. The LDAP filter was: filter = "(uid=%{Stripped-User-Name:-%{User-Name}})" Is now: filter = "(|(cn=%{Stripped-User-Name:-%{User-Name}})(mail=%{User-Name}))" The proxy.conf lines right before it's defaulted to eduroam: realm ettyhillesumlyceum.nl { } Anyone has an idea why radtest would behave differently from an 802.1x login? Regards, Bas

What are options do I have to use to compile freeradius with ldap support turned on? I tried ./configure -with-ldap but that didn't seem to work I still get an error about not being able to find rlm_ldap. I checked the mail archives but I couldn't find anything. Thanks, Chris

Group questions..several group memberships to one account. FreeRADIUS Version 2.1.10
by Alexander Silveröhrt 12 Apr '13

12 Apr '13

Hello, Never played around with groups using rlm_sql and the default schema.. I am reading what i assume is saying that it should be possible to have several groups to a account and each group should be able to supply that specific groups radgroupreply attributes.. Number 4 below sure sounds like it should get all the accounts groups first and then process them according to priority? Below test shows it only reads the first group? And no matter what priority.. Is that how it should work or what am i missing here? 1.Search the radcheck table for any check attributes specific to the user 2.If check attributes are found, and there's a match, pull the reply items from the radreply table for this user and add them to the reply 3.Group processing then begins if any of the following conditions are met: ◦The user IS NOT found in radcheck ◦The user IS found in radcheck, but the check items don't match ◦The user IS found in radcheck, the check items DO match AND Fall-Through is set in the radreply table ◦The user IS found in radcheck, the check items DO match AND the read_groups directive is set to 'yes' 4.If groups are to be processed for this user, the first thing that is done is the list of groups this user is a member of is pulled from the usergroup table ordered by the priority field. The priority field of the usergroup table allows us to control the order in which groups are processed, so that we can emulate the ordering in the users file. This can be important in many cases. 5.For each group this user is a member of, the corresponding check items are pulled from radgroupcheck table and compared with the request. If there is a match, the reply items for this group are pulled from the radgroupreply table and applied. 6.Processing continues to the next group IF: ◦There was not a match for the last group's check items OR ◦Fall-Through was set in the last group's reply items (The above is exactly the same as in the users file) 7.Finally, if the user has a User-Profile attribute set or the Default Profile option is set in the sql.conf, then steps 4-6 are repeated for the groups that the profile is a member of.

Performing an additional check on the credentials
by Romeo Mihalcea 11 Apr '13

11 Apr '13

I successfully managed to deploy a freeradius server and created a python script which does an additional check on the user (incoming request). I checked the internet (resources for freeradius are pretty horrible) and only found a thread which explains some basics about adding a python script to the process. Right now I have it inside /etc/freeradius/sites-enabled/default under the authorize section: update control { Auth-Type := `/usr/bin/python /etc/test.py '%{User-Name}' '%{User-Password}'` } My test.py file spits Reject or Accept. I also have sql authentication setup with freeradius and the problem is that, if my script returns Accept any other authorization request under is ignored; response will still be an Accept even if sql check rejects the user. >From what I understand I should pass a noop instead of Accept to allow freeradius to continue and only pass Reject if I need to reject the user but If I respond with noop the server complains (probably because it expects a reply for Auth-Type as I coded it). Someone on serverfault suggested I shouldnt use unlang to call a python script and I should use rlm_python but I really have no idea how to even start calling my script. Any ideas? Maybe I need to add my code to the Authentication. section? How?

freeRadius 2.1.10 PEAP/MSCHAPv2 w/ Active Directory
by trevor_marquis＠selinc.com 11 Apr '13

11 Apr '13

Hello all, I'm new to freeRadius and am using freeRadius version 2.1.10 for some lab testing. I've got freeradius extracting users and passwords from an Active Directory database. I'm using PEAP/MSCHAPv2. All configs have been working until about a week or so ago. All of a sudden, my mschapv2 challenge/response is not correct. Not sure where exactly the problem is occurring so I've posted the debug output below. If other config files are necessary, I can post them too. Thank for any help.

Need both Local (MySQL database) and Active directory authentications.

Hi all, I have set up Freeradius (v.2.1.10) to do password authentication from MySQL database and it works fine but now I need to make some users be able to authenticate against Active directory accounts. I’ve setup winbind to authenticate windows accounts and it works but as a result freeradius lost ability to authenticate by local database. So if I comment the line: ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{%{Stripped-User-Name}:-%{User-Name:-None}} --challenge=%{mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00}" in /modules/mschap file then local database authentication works fine but Active directory doesn’t. With uncommented ntlm_auth Active directory works but local database doesn’t. The WiFi access points that queries the radius using WPA-Enterprise, so passwords encrypted in EAP messages and so there is no another way to validate the passwords, it have to go through mschap module anyway. Is there a way to tell mschap to use ntlm_auth depending on field in MySQL table and use the internal mechanisms if plain text passwords available in the MySQL table?

Hello, I have installed Debian Squeeze 6.0 with freeradius 2.1.10 + accel-ppp (PPPoE). Everything is working fine, but radwho and radwho -s doesn't return full username fetched from /etc/passwd. All users have real linux account and proper entry in /etc/freeradius/users. All details login and passwords are included in users file. In old freeradius 1.1.3 I got radwho output: zycha AnetaZych PPP S338 Sun 16:28 127.0.0.1 192.168.1.223 -where AnetaZych is full name fetched from /etc/passwd in new I have: zycha zycha PPP S338 Sun 16:28 127.0.0.1 192.168.1.223 Could you please advice where should I change configuration? I have made strace on radwho and I didn't find and information for checking file /etc/passwd. Please advice Best regards Marek
