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.

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

user-group for rejected users
by Fabricio Viana 21 Mar '17

21 Mar '17

Hello! Let´s suppose the following situations: 1) User exists but the password is wrong 2) User does not exist In both cases the answer is REJECT. It happens that certain hardware is making endless attempts that eventually saturating the server. - It is possible to cause the server, instead of rejecting the users, accept the login but responds ACCEPT with "framed-pool = pool-block" ? or/and - Is there any way to put REJECT users in a given group by default? Thanks! Fabricio

No Logon Servers error with FreeRADIUS + NTLM
by Stefan Paetow 19 Feb '16

19 Feb '16

Hi, I know this is not a problem with FreeRADIUS, however, there are several people on this list who run FreeRADIUS with Active Directory as a back end and I need their advice on this. I've run into the dreaded "No logon servers (0xc000005e)" error with NTLM. In the past I've found that the computer password for the server expired on AD and that it was either fixed by rejoining, or by tweaking the password's expiry. Do any AD folk on the list know what we can do to get this stable and that this does not occur again? Any ideas will be very useful. :-) With Regards Stefan Paetow Moonshot Industry & Research Liaison Coordinator t: +44 (0)1235 822 125 Janet, the UK's research and education network.

stale session
by Sergio Diaz 02 Sep '15

02 Sep '15

Hello Guys, I am simulating the problem on what if the AP goes down (due to various reasons). I observed that user is not properly disconnected and result is stale session. When the AP is up and when the previous user tries to log in he/she gets login failed message because "Simultaneous-Use" is in effect while previous session is still ticking. How can prevent and fix this? Saludos Cordiales, Sergio Diaz Infraestructura TI 01(55) 5265.0145 (044) 55.28.99.95.71 sdiazf(a)logitel.com.mx www.logitel.com.mx

session log in SQL
by Khapare Joshi 31 Jul '15

31 Jul '15

Now its time to configure to log into SQL :) Until now we uses cisco wireless controller and only allow two connection for all users. I wanted to implement Simultaneous-user based in student and staff. and want to use sql for it. My users are authenticate against AD (samb +ntml_auth). So here is what I did : 1. Created database radius. 2. Populated admin.sql into the mysql 3. Populated schema.sql into the radius database 4. Enabled sql.conf in /etc/raddb/radius.conf 5. Disabled radutmp and enabled sql in accounting section in /etc/raddb/site-enabled/default 6. So, added DEFAULT Simultaneous-Use := 2 in /etc/raddb/users file for testing 7. restarted radius - try logging few users But I do not see any tables in radius database been updated. I just wanted to use session for the simultaneous user for restrict user. if this works then I can write regex to query LDAP if x is staff or student. Point me if i am doing wrong or some docs where I can see more reading reading reading. K

Simultaneous-Use in proxy
by Renato Sousa 13 Jul '15

13 Jul '15

Hello everyone, I need to restrict simultaneous logins but the freeradius server which receives the authentication does not implement this restriction. This server receives the authentication different departments and this restriction should only be applied in my department. It is possible to create a proxy that forwards authentication for global freeradius server and controls the simultaneous logins? How to return the parameter Simultaneous-Use via proxy? Any help will appriciate. Best Regards, Renato L. Sousa

Acess reject dropped by freeradius
by sai ram 03 Jul '15

03 Jul '15

Hi, I am using freeradius 2.2.1 Whenever I use wrong credentials, NAS sends access reject. Access reject packet is received when I do a packet capture. But freeradius doesn't acknowledge access reject the same way it does for access accept. I changed reject_delay parameter to 0. But I still don't receive the access reject from freeradius. So every time wrong credentials is entered, I get time out instead of access reject. Is there some other configuration is need to change ? Regards, Sairam
