Authenticate to AD but only allow certain group
by Brian C. Huffman 16 Aug '25

16 Aug '25

All, I've got authentication working nicely with MSCHAP, but now I'd like to only allow users that are members of a certain AD group. I would prefer to have this happen only when requests come from a specific client (wireless access point). In this case the idea is to have users only be able to get wireless access when they're in a specific AD group. How can I do this in freeradius? Thanks, Brian

Detailed Logging freeradius Request Packets
by Jean-Francois Mousinho 28 Oct '19

28 Oct '19

Hi, I've tried to find a way of detail logging the packets sent by freeradius to the client in the authentication phase but didn't found a way of doing it. Maybe I've not looked correctly so I'm asking if it's actually possible? I was able to log detailed packets sent by the client (Response packets) but not the ones sent by freeradius to the client (except accounting and proxied ones). Thanks for your time.

Tough time getting FreeRADIUS 3.0.9 to work with mysql
by Kwesi Yankson 19 Nov '18

19 Nov '18

Hello,I am a freeRADIUS 2.x user and want to start using freeRADIUS 3.x.xI have installed freeRADIUS 3.0.9 and done a lot of reading since I want to avoid being told to "RTFM"I can't seem to get an Access-Accept when I do a radtest for MySQL users. I'm sure I'm missing something (still adjusting to the difference between the two version). Can someone help or point me in the right direction?

FreeRADIUS and Active Directory Integration
by Scott Pickles 19 Nov '18

19 Nov '18

I'm sure you're reading the subject going "ugh not another one". But there is so much documentation out there and all of it slightly different that I don't know which end is up at this point. I would like to use FreeRADIUS to authenticate VPN users and wireless, and I'm working on VPN right now. From what I understand so far, I want to use LDAP to check if the person is in the right group first, and if not reject them. If they are in the right group then authenticate using ntlm_auth. I am also understanding that the place to do this is no longer the users/authorize file and that it should be done in the 'default' file using 'unlang'. Is this correct so far? If so, can someone give me an example of the 'unlang' portion?

LDAP (rlm_ldap) Version 3.0.9
by Scott Pickles 19 Nov '18

19 Nov '18

I'm running a CentOS 7 environment and I just did a fresh install of v3.0.9 of FreeRADIUS. I also installed version 1.0.2d of openssl so I'm not subject to heartbleed. When I installed the ldap module, yum downloaded version 3.0.4 and also installed a heartbleed vulnerable version of openssl and broke my install. I know how to patch radiusd.conf for the heartbleed vulnerability but I'd rather not. So I removed the ldap module, re-installed openssl 1.0.2d and recompiled FreeRADIUS. Is there a repo that will provide me with a 3.0.9 version of the ldap module? If not, can I compile and point to my lib directory for openssl 1.0.2d instead? Yum downloads an RPM and I don't know of a way to simply extract that, so I am looking for a way to compile from source for either version 3.0.4 or 3.0.9 if it exists. Don't know where to look for the source(s).

Reply-Messages based on different conditions

Hello,I'm using freeRADIUS 3.0.9I use the sql module to do AAAI currently want to use unlang to do the following.Assuming there a user called "bob" who has the password "pass"I want unlung to compare the username and password in such a way thatif username is "bob" and password is not "pass" a Reply-Message such as "Incorrect password for user "bob" " will be sent. This scenario is for only if the username bob exists.If username "bob" does not exist the a Reply-Message = "User "bob" not found" Can someone help me with the unlang which will do this?

SNIP ... ] The only other thing I can think of is that the user that I'm binding to AD with to read information doesn't have the right permissions? But I would also think that the bind wouldn't be successful in the first place for the module if that were the case? I don't know what direction to take this in next to get more information. I would check the logs but since I'm running the server in debug mode the logs would just be duplicates of what I already have, correct?

3.0.4: binary LDAP attributes
by Nikolai Kondrashov 24 Mar '17

24 Mar '17

Hi everyone, Our (Red Hat) QA was testing the effect of this entry in 3.0.4 ChangeLog: * Modify pairparsevalue to deal with embedded NULLs better, and use the binary versions of attribute values in rlm_ldap. They have noticed that binary LDAP values get truncated on embedded zero characters (\0) in RADIUS replies, in radiusReplyMessage in particular. I.e. for radiusReplyMessage:: cmVwbHkgd2l0aCBhAGI= The response output by radtest was Reply-Message = 'reply with a' The network capture also showed that RADIUS reply packets contained truncated values. Is this intended, or was there a fix for this? In related discoveries, it seems that backslashes get removed from LDAP attribute values in RADIUS replies, so radiusReplyMessage: reply with a\0b becomes Reply-Message = 'reply with a0b' in radtest output. Is this intended? Thank you. Nick
