Using freeradius and 802.1x for dynamic VLAN
by lvizcardof＠unsa.edu.pe 11 Oct '07

11 Oct '07

Hello, I use freeradius-1.0.4-1.FC4.1 version in a PC Linux Fedora Core 4. This radius server authenticates to user in function to his login and key, if the information is correct the radius server must send to user to the vlan 2 according to forms in the file users of the radius server. This is the configuration in the file users from radius server: ***************************************************************** carlos Auth-Type := EAP, User-Password == "carlos" Service-Type = Framed-User, Tunne-type = VLAN, Tunnel-medium-type = IEEE-802, Tunnel-Private-Group-Id = 2 ***************************************************************** I have the followin problem . When I authenticate to the user with login and key It sends by defect to the vlan 1. I have a switch DELL PowerConnect 5324. In this switch I have formed the ports to 802.1x and I have two vlans: the vlan2 and vlan3 This is all the configuration in my switch: ***************************************************************** console# show running-config vlan database vlan 2-3 exit interface ethernet g1 switchport access vlan 2 exit dot1x system-auth-control interface range ethernet g(7-10) dot1x port-control auto exit interface range ethernet g(7-10) dot1x re-authentication exit interface vlan 2 ip address 10.20.10.253 255.255.255.0 exit interface vlan 3 ip address 192.168.2.253 255.255.255.0 exit ip default-gateway 10.20.10.1 radius-server host 10.20.10.13 auth-port 1645 timeout 3 radius-server key misecreto aaa authentication dot1x default radius username admin password 7d8c9c8b116cdfe3fb091f4c1ac684de level 15 encrypted ***************************************** The problem that I have is that when I authenticate to user with his login and key, The radius server sends the user to the vlan 1. Who can I do so that radius server sends the user to the vlan that I select? , in this case is the vlan 2. I think that. I review all the information about how to form the radius server but, I don't know what more do. do you have an idea of, how can I solve this problem? ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Get raddb/certs/bootstrap to work on systems where make is not gnu make
by Scott Lambert 11 Oct '07

11 Oct '07

Attached is a simplistic patch to get raddb/certs/bootstrap to work on systems where make is not GNU make. The patch is to: radiusd/configure to add ./raddb/certs/bootstrap to the ac_config_files. radiusd/raddb/certs/bootstrap to get it ready to be repo-copied to radiusd/raddb/certs/bootstrap.in. I think radiusd/raddb/certs/bootstrap with then need to be "cvs rm"ed. Hopefully it will be useful. -- Scott Lambert KC5MLE Unix SysAdmin lambert(a)lambertfam.org

Re: 802.1x & kerberos

We also have this working with the below settings. However in running ver 1.1.6 (maybe others) we have found that there is some sort of problem that will cause the Freeradius server to crash. This seems to be tied to request with incorrect passwords as notated by the following in the log: Thu Oct 11 10:01:03 2007 : Auth: rlm_krb5: [UserName] krb5_g_i_t_w_p failed: Decrypt integrity check failed Has anyone else seen this or have suggestions for me on this. > Date: Thu, 11 Oct 2007 15:00:39 +0100 > From: A.L.M.Buxey(a)lboro.ac.uk > Subject: Re: 802.1x & kerberos > To: FreeRadius users mailing list > <freeradius-users(a)lists.freeradius.org> > Message-ID: <20071011140039.GA23584(a)lboro.ac.uk> > Content-Type: text/plain; charset=us-ascii > > Hi, > > > It works w/o EAP.

eDirectory Authentication
by Brad Lachel 11 Oct '07

11 Oct '07

We are currently using our RADIUS server to do one thing. It is authenticating wireless users via Mac address through access points. Very clean, very simple. We would like to increase the security a bit by having the users authenticate against eDirectory as well. If a user tries to get on the network, his MAC is passed to the RADIUS server. If the MAC is validated, the request is passed to the Novell Server, the user is asked to enter his password, and then he is allowed in. I have setup my config files according to several eDirectory/FreeRADIUS FAQ articles that I have found, but I am still having a few issues. 1: I am never asked for a password 2: rlm_ldap: When I attempt to get access, I get an error message "could not start TLS operations error" Below are some clips from my configurations as well as the access messages as I receive: ACCESS ATTEMPT: rad_recv: Access-Request packet from host 172.16.14.23:1812, id=1, length=73 User-Password = "xxxxxx" User-Name = "0016cb-b64f93" NAS-Identifier = "172.16.14.23" NAS-IP-Address = 172.16.14.23 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 0 modcall[authorize]: module "preprocess" returns ok for request 0 radius_xlat: '/usr/local/var/log/radius/radacct/172.16.14.23/auth- detail-20071011' rlm_detail: /usr/local/var/log/radius/radacct/%{Client-IP-Address}/ auth-detail-%Y%m%d expands to /usr/local/var/log/radius/radacct/ 172.16.14.23/auth-detail-20071011 modcall[authorize]: module "auth_log" returns ok for request 0 modcall[authorize]: module "chap" returns noop for request 0 modcall[authorize]: module "mschap" returns noop for request 0 rlm_realm: No '@' in User-Name = "0016cb-b64f93", looking up realm NULL rlm_realm: No such realm "NULL" modcall[authorize]: module "suffix" returns noop for request 0 rlm_eap: No EAP-Message, not doing EAP modcall[authorize]: module "eap" returns noop for request 0 users: Matched entry DEFAULT at line 153 users: Matched entry 0016cb-b64f93 at line 222 modcall[authorize]: module "files" returns ok for request 0 rlm_ldap: -

Re: configure MSCHAPV2 authentication protocol
by tnt＠kalik.co.yu 11 Oct '07

You can start by deleting that. It's totally wrong. That's not a CHAP-Password (it' not encrypted at all) and you can't use that attribute with MS-CHAPv2 anyway. Than read available information: http://wiki.freeradius.org/SQL_HOWTO Start by populating radcheck table, test it, and (when it works) then populate the rest.

configure MSCHAPV2 authentication protocol
by yangcuilin 11 Oct '07

11 Oct '07

Hi, Attached is my configuration file. I want to use MSCHAPv2 authentication protocol in my FreeRADIUS. This is my first time to configuration about MSCHAPV2. May be something wrong with the file. Does it need configuration at other file? Please give me some advice. Thank you very much! Appreciated in advance. Rock

Problem with LDAP and Groups
by Bryan Evege 11 Oct '07

11 Oct '07

Hello all. First off here's what I want to accomplish in the end. Use LDAP as the backend to store all user information including radius attributes, shell info and access to specific devices in specific locations. For example, Johnny needs access to all linux boxes in Atlanta and priv-level 15 on cisco routers in Denver. Fred needs read/write access to all packet shappers in Denver and read only to all cisco devices in Atlanta and Denver. You get the picture. I've setup a test server following the document in /opt/freeradius/share/doc/freeradius/ldap_howto.txt without much difficulty. This method does a good job of allowing only certain groups to access certain devices without messing with the huntgroups. Here's the problem. When a user logs in and is a member of more than one group radius only uses the first one to match. I've included the users file below. For example, if the user is a member of the cisco group and the packeteer group only the packeteer group information gets passed back because it is found before the cisco group. Is there a way to say that the request is from a Cisco box so only look for the user in the cisco group? If the user is then found in that group then pass back the correct attributes from their profile. I know I would have to define what a "cisco box" is, probably by IP. Please let me know if this is even possible and if so provide an example. If it is not possible please provide some direction on how to go about doing this.

Question regarding the Expiration attribute
by Terry Pelley 10 Oct '07

10 Oct '07

FreeRADIUS Version 1.1.7 on Novell SLES10 The question is simple but I can't seem to find the answer to it so I will apologize in advance. Can some one tell me the format for entering the date in the Expiration attribute? I'm using the users file to authenticate users on a small wireless network. ie. testuser User-Password == "testpass" Expiration = ??? (lets use today 10 October 2007 as an example) thanks in advance.
