Hi, I am trying to authenticate users using eap/ttls and internal mschap-v2. Currently I haven't set any auth-type in the users, just a password. This because auth-type := EAP (which is sugested in quite a few howto's is appearantly wrong acccording to the list and the docs. It seems like I'm allmost there cause I get a certificate at the supplicant. (O well, looks like there's something working:) I've googled around but have not found a solution, I hope someone could give me a hint in the right direction. Thanks a lot for any help, Kozy. here are the last lines of freeradius' output: Processing the authorize section of radiusd.conf modcall: entering group authorize for request 5 modcall[authorize]: module "preprocess" returns ok for request 5 modcall[authorize]: module "mschap" returns noop for request 5 rlm_realm: No '@' in User-Name = "TestUser", looking up realm NULL rlm_realm: No such realm "NULL" modcall[authorize]: module "suffix" returns noop for request 5 rlm_eap: EAP packet type response id 5 length 143 rlm_eap: No EAP Start, assuming it's an on-going EAP conversation modcall[authorize]: module "eap" returns updated for request 5 users: Matched entry TestUser at line 206 modcall[authorize]: module "files" returns ok for request 5 modcall: leaving group authorize (returns updated) for request 5 rad_check_password: Found Auth-Type EAP auth: type "EAP" Processing the authenticate section of radiusd.conf modcall: entering group authenticate for request 5 rlm_eap: Request found, released from the list rlm_eap: EAP/ttls rlm_eap: processing type ttls rlm_eap_ttls: Authenticate rlm_eap_tls: processing TLS rlm_eap_tls: Length Included eaptls_verify returned 11 eaptls_process returned 7 rlm_eap_ttls: Session established.

SSL Problem???
by DeYoung, Brandon 17 Aug '05

Hello all, I have been successfully providing 802.1x authentication to my wireless users for approx six months. This was implemented using ntlm_auth, PEAP, and MSCHAPV2 (windows XP client) against an Active Directory backend. We had a power spike, which produced multiple simultaneous drive failures and there is little but corrupted data left on my server. I managed to retrieve my config files from backup, but had to do a clean install, recreate SSL certs, etc. I am using freeradius-1.0.0-5 on Suse 9.2 Pro. I *believe* this snippet from my debug output shows the problem: ----snip----- eaptls_process returned 3 TLS_accept:error in SSLv3 read client certificate A rlm_eap_peap: EAPTLS_SUCCESS -----snip------ This would *seem* to indicate a problem with my certificate generation. I've deleted and re-created my certs on both the server and the client 4 times now. I've tried giving the certs different names, thinking that they weren't deleted correctly from WinXP's mmc panel. I'm following this howto on cert creation: http://jeremy.austux.net/resources/network/eaptls.html I'm pretty sure that this is the same howto I followed last time and it, "just worked". I'm only about 95% sure that my certs are the problem. If someone could at least confirm that, it would help. If anyone can pinpoint my issue more precisely I would be eternally grateful, as I'm really in a bind right now. Any and all suggestions are most welcome. Thanks much! ~Brandon ***************************** **Exhaustive info below:***** ***************************** I have the following relevant software installed: samba-3.0.9-2.3 samba-winbind-3.0.9-2.3 openssl-0.9.7d-25 Here are a couple radtest outputs (note: the user here is local, not AD and obviously this is by-passing certificates). houston:/etc/raddb # radtest test testing localhost 43.191.108.31 SECRET Sending Access-Request of id 135 to 127.0.0.1:1812 User-Name = "test" User-Password = "testing" NAS-IP-Address = houston NAS-Port = 43 rad_recv: Access-Accept packet from host 127.0.0.1:1812, id=135, length=20 houston:/etc/raddb # houston:/etc/raddb # radtest test wrongpw localhost 43.191.108.31 SECRET Sending Access-Request of id 156 to 127.0.0.1:1812 User-Name = "test" User-Password = "wrongpw" NAS-IP-Address = houston NAS-Port = 43 rad_recv: Access-Reject packet from host 127.0.0.1:1812, id=156, length=20 houston:/etc/raddb # .....So that works as it should.....

Proxying Machine Authentications
by King, Michael 17 Aug '05

17 Aug '05

I currently have our wireless users authenticating to our Active Directory 2003 domain using PEAP and TTLS. We want to proxy our machine authentications off to something else that can authenticate them. Does anyone have any examples of how to do this? I know all the machine accounts show up on my NAS as host/machinename Whereas my users are : Domain\Username Or Username

LDAP attributes into freeradius
by Joe H 17 Aug '05

17 Aug '05

Here is my goal: I would like to assign an attribute to certain users in ldap and have freeradius look for that attribute to determine whether or not to reply back to the NAS device with an IP address pool name. The users with the attribute set would not have the Pool sent and the users without the attribute set would have the pool sent. Here is the rule that I have set for it in the users file: DEFAULT Huntgroup-Name == "dialup" Idle-Timeout = "1800", Fall-Through = Yes DEFAULT Huntgroup-Name == "dialup", No-Pool != "1" USR-Framed_IP_Address_Pool_Name = "POOL", Idle-Timeout := "120", Fall-Through = Yes dialup is the ldap module I have setup in the radiusd.conf file. Here is that entry: ldap dialup { server = "localhost" identity = "cn=Manager,dc=domain,dc=com" password = "*********************" basedn = "ou=Users,o=domain.com,dc=domain,dc=com" filter = "(uid=%{Stripped-User-Name:-%{User-Name}})" start_tls = no tls_mode = no dictionary_mapping = ${raddbdir}/ldap-dialup.attrmap ldap_connections_number = 288 groupname_attribute = gidNumber groupmembership_filter = "(uid=%{Stripped-User-Name:-%{User-Name}})" timeout = 4 timelimit = 3 net_timeout = 1 compare_check_items = no } The problem I'm seeing is that radius doesn't seem to use the value of No-Pool. I have it in the ldap-dialup.attrmap as: checkItem No-Pool radiusNoPool radiusNoPool is the ldap attribute with a value of 1. Where else do I need to add the new attribute No-Pool in order for freeradius to use it? Joe H. GWI Operations.

Debian 802.1x LDAP
by Cian Phillips 17 Aug '05

17 Aug '05

Greetings. I'm trying to get a Debian (stable) box set up to authenticate users for our Cisco Wireless Control Software via LDAP. I have tried the Debian package and can get LDAP running easily. When I try to get the eap/tls stuff working it gives me an error about missing libraries. rlm_eap: Failed to link EAP-Type/tls: rlm_eap_tls.so: cannot open shared object file: No such file or directory I have googled this and found some messages that suggest compiling from source and using the --shared-disabled flag at compile time but I've tried building from source and can't even get LDAP working.. each time I un-comment the ldap line from the radiusd.conf file and try to start using radiusd -x I get a segfault. Ideally I would like to stick with Debian as that is what my other production servers are but would be willing to use something else if it makes easier work of this process. If anyone has gotten Debian + 802.1x + LDAP working or even just 802.1x + LDAP I could really use some pointers if even just to tell me it is or isn't possible. Thanks in advance.

I can see that I could end up with a very large users file using this method. Is there any limit on the size of the users file? In the near future we may have something like 800000 entries in there. Is this where you would normally look to use a database backend? Thanks Ben

freeRadius Authorization
by abera 17 Aug '05

17 Aug '05

Hi, I have small newbie questions.. I want to configure freeRadius for authentication & authorization. I am able to do proper authentication. 1) I want to configure my users in multiple groups (depending on their roles). How to do that? 2) And what is the common practice for this? How this is managed in any enterprise servers / enterprise networks who uses radius server for the AAA? Thanks...

FreeRadius 1.0.4 crashing when getting Request
by Sebastian Mauer 17 Aug '05

17 Aug '05

Hello there, I have a little problem with setting up FreeRADIUS with MySQL Support properly. My Linux Distro is Debian Sarge 3.1. I installed all necessary libraries and compiled FreeRadius with MySQL enabled. Then I installed all necessary MySQL tables and configured FreeRadius to do EAP-TLS with MySQL as backend. All seems to work nice until the server finally recieves a first request. The server segfaults and that's the end. I have no idea what could have gone wrong Does someone of you have an idea what to do? Sincerely, Sebastian Mauer
