infamous AD integration

16 Jun '16

hi users, I know there are howtos and as a novice I've been reading whatever I could find but I still fail to have my radius 3.0.4 talk to AD 2014. I'm hoping some expert would share a pointer to a nice & working tutorial on how to setup active directory. I've gotten it up to winbind bit working fine, seems samba+winbind are doing ok, and before I dump my configs I'd like to say I followed these: https://www.unixmen.com/freeradius-active-directory-integration-with-ntlm-m… http://deployingradius.com/documents/configuration/active_directory.html ... and a few more. What I'm hoping to have might be a bit nonstandard(?) - it might be that I don't need that, that I don't need full domain name. before I dump the configs here, I test radius: $ radtest -t mschap pe243(a)my.domain.local my.Pass $(hostname -f) 1812 radius.Pass and I see: (2) } # filter_username filter_username = notfound (2) [preprocess] = ok (2) [chap] = noop (2) mschap : Found MS-CHAP attributes. Setting 'Auth-Type = mschap' (2) [mschap] = ok (2) [digest] = noop (2) suffix : Checking for suffix after "@" (2) suffix : Looking up realm "my.domain.local" for User-Name = "pe243(a)my.domain.local" (2) suffix : No such realm "my.domain.local" (2) [suffix] = noop (2) eap : No EAP-Message, not doing EAP (2) [eap] = noop (2) [unix] = notfound (2) [files] = noop (2) [expiration] = noop (2) [logintime] = noop (2) WARNING: pap : No "known good" password found for the user.

Freeradius v3.0.11 LDAP "userpassword: {SASL}bob" problems
by Kouata Modibo 16 Jun '16

16 Jun '16

Hello, I installed freeradius version 3.0.11. I have two LDAP directory servers. An LDAP server prinicpal A that contains all users. and an LDAP server B directly connected to radius server (same network). LDAP server B contacts the prinicpal server A when needed to authenticate a user. The password fields of users on the server B are in the form userpassword: {SASL}bob bob is the username. Here is a part of debug output when authentificating a user: rlm_ldap (ldap): Reserved connection (2) (8) ldap: EXPAND (uid=%{%{Stripped-User-Name}:-%{User-Name}}) (8) ldap: --> (uid=kouata) (8) ldap: Performing search in "dc=example,dc=com" with filter "(uid=bob)", scope "sub" (8) ldap: Waiting for search result... ldap: User object found at DN "uid=bob,ou=People,o=Myentreprise,dc=example,dc=com" (8) ldap: Processing user attributes (8) ldap: control:Password-With-Header += '{SASL}bob' rlm_ldap (ldap): Released connection (2) (8) [ldap] = updated (8) [expiration] = noop (8) [logintime] = noop (8) pap: Unknown header {{SASL}} in Password-With-Header, re-writing to Cleartext-Password (8) pap: Removing &control:Password-With-Header My radius server can not authenticate users from LDAP server B. Can anyone help me? thank you!

Calling station id has SSID in it
by Alex Sharaz 15 Jun '16

15 Jun '16

Hi all, Not a freeradius question but .... Someone out on eduroam has got their wireless mobility controller set up to include the SSID in their calling-station-id attribute that gets passed back to us. e.g. radius.log.30.gz:Mon May 16 19:12:59 2016 : Auth: (19885) Login OK: [ sgvk500(a)york.ac.uk] (from client roaming0.ja.net port 9 cli 98-b8-e3-65-72-fc;eduroam) This is on FR 3.0.12 I've changed the postgresql column definition for calling-station-id to be of type macaddr from varchar. As a result insert statements are getting rejected. What's an easy way of stripping out the ;eduroam but and making both postgresql and our db manager happy? Rgds Alex

Hi all! I'm using this nice program on an old, linux nas and it works perfectly. But now I bought a dongle and attached to the nas.

Freeradius v3.0.11 LDAP users password encyption and "userpassword: {SASL}bob" problems
by Kouata Modibo 15 Jun '16

15 Jun '16

Hello, I installed freeradius version 3.0.11. I have two LDAP directory servers. An LDAP server prinicpal A that contains all users. and an LDAP server B directly connected to radius server (same network). LDAP server B contacts the prinicpal server A when needed to authenticate a user. The password fields of users on the server B are in the form userpassword: {SASL}bob bob is the username. Here is a part of debug output when authentificating a user: rlm_ldap (ldap): Reserved connection (2) (8) ldap: EXPAND (uid=%{%{Stripped-User-Name}:-%{User-Name}}) (8) ldap: --> (uid=kouata) (8) ldap: Performing search in "dc=upmc,dc=fr" with filter "(uid=bob)", scope "sub" (8) ldap: Waiting for search result... ldap: User object found at DN "uid=bob,ou=People,o=Myentreprise,dc=example,dc=com" (8) ldap: Processing user attributes (8) ldap: control:Password-With-Header += '{SASL}bob' rlm_ldap (ldap): Released connection (2) (8) [ldap] = updated (8) [expiration] = noop (8) [logintime] = noop (8) pap: Unknown header {{SASL}} in Password-With-Header, re-writing to Cleartext-Password (8) pap: Removing &control:Password-With-Header My radius server can not authenticate users from LDAP server B. Other problem: When the password of users in the ldap directory are encrypted with SHA1 for example, ms-chapv2 authentication fails, but when it is stored in clear, successful authentication. Is this means that ms-chapv2 can't work with encrypted password? Is there a way to use ms-chapv2 but not stock clear-text password on LDAP? Can anyone help me to find my problems? thank you. *Here the debug output: * *-- * Server was built with: accounting : yes authentication : yes ascend-binary-attributes : yes coa : yes control-socket

Radius - CISCO Mac Authentication
by sokphak touch 15 Jun '16

15 Jun '16

Dear Radius Community, I would like to test one lab as describe below. There are few CISCO Layer 2 switches located by building floors. I have a few clients in the organization. I want every user connected to any switch will getting the VLAN ID assignment from Radius server. Suppose it will authenticated by MAC address of each PCs. If the MAC not exist in radius database, client's pc could not have any access to network. I'm not sure if CISCO and Radius could do as requirement above? Thanks for input from everyone. Regards, Victor

freeradius load and message handling
by liran kessel 14 Jun '16

14 Jun '16

Hi, we have a freeradius server collecting accounting events from a few Nokia GGSN’s and are storing them into the MySQL DB. Now that we have activated all messages we are receiving around 20K messages a minute, and have started seeing these events in the radius.log Tue Jun 14 22:53:33 2016 : Info: WARNING: Please check the configuration file. The value for 'max_requests' is probably set too low. it was originally set to 1024, when we increased it and set it to 4096 the amount of such events was reduced but still didn’t disappear. If we set it higher (6100 for example) we start getting these errors Tue Jun 14 21:30:02 2016 : Error: Received conflicting packet from client localhost port 41935 - ID: 200 due to unfinished request 192178. Giving up on old request. why does this event appear? what would be the best way to manage this situation? The server has 8 Cores and 4GB of RAM. It seems that the CPU isn’t overly loaded, but our RAM is almost completely used by the Radius and Mysql processes. Will adding RAM to this server help us? or isn’t it the bottleneck for this issue? Thanks Liran

Freeradius and 2 Factor Authentication
by Aaron Smith 14 Jun '16

14 Jun '16

I've been working on setting up a Microsoft Routing and Remote Access server that uses Freeradius for Authentication. Out of the box, it works fine with simple user entries in the "users" file. This is with both the Ubuntu 14.04 apt-get installations of Freeradius (2.1.x) as well as a compiled from source version of Freeradius 2.2.9. I run in to trouble when I try to add two factor authentication to the mix. I'm trying to use LinOTP as a possible replacement of our CryptoCard Blackshield implementation. The problem is that both products seem to only work with unencrypted passwords. LinOTP has two options for Freeradius authentication. There is a linotp2 module that can be compiled and installed along with Freeradius, and there is also a perl script that can be linked in with the rlm_perl module. Looking at the perl script, it is expecting to find the attribute "User-Password" in the radius request, which it uses, along with the username, to go to a web URL on the LinOTP server to verify authentication. I suspect that the linotp2 module works similarly. The documentation provided by LinOTP says to set "DEFAULT Auth-Type := linotp2" if you're using the module or "DEFAULT Auth-Type := perl" if you're using the perl script in the freeradius users file. Now, this will "work" for narrow authentication types like Microsoft's SSTP with an unencrypted password, but I'd like this solution to be more widely usable (Macs, iOS devices, etc) and use something like IKEv2, but that uses EAP-MSCHapv2. If I try that, the authentication fails saying there is no password. My question is...am I tilting at windmills trying to make this work? I feel like it *should* be possible to do 2 factor authentication without having to resort to PPTP/unecrypted password or microsoft's proprietary SSTP. Is there a way to have freeradius pass the MSChapv2 password to a perl script or another module? Or perhaps it's possible to modify the perl script so it can accept an encrypted password? I feel like maybe there's a way to configure authentication in the "inner-tunnel" freeradius site that would make this possible. EAP-MSChapv2 authentication works with a plain, unencrypted password in the users file, so it obviously HAS the password that the user sends in SOME fashion. A secondary question is that I imagine I can't be the first person to use Freeradius with 2 factor authentication. I'd be curious to know how other folks have tackled this project and what products they used to accomplish it. ----------------------------------- Aaron Smith System Administrator Information Services Kalamazoo College 1200 Academy Street, Kalamazoo, MI 49006 (269) 337-7496 Aaron.Smith(a)kzoo.edu
