Mysql with crypted password
by Alessandro Agostini 27 Jun '06

27 Jun '06

Hi to all, I have successfully installed secure2 with 3Com WX1200 switch and AP 3Com 2750, with authentication PEAP-EAP/MSCHAPv2. Authentication radius ask to mysql tables the credentials stored in plain text. Now, my problem is: I don't like plain text password in my MySQL Table. So I ask you. Which is the possible scenario to have crypted password stored in MySQL. Thank you Alessandro Agostini

basic handling of multiple EAP-Methods by freerad
by Rainer Brinkmann 27 Jun '06

27 Jun '06

Hello, we wonder, how a freeradius can request a client to use a fixed EAP-Method: so its defined: Client starts with EAP-Start-Msg Radius wants EAP-Identity Client answers with Username or Hostname NOT using a special EAP-Method Radius now starts communiucating with the first EAP-Packet, using the special EAP-Method Question: you run in your wireless LAN many SSIDs: SSID1 shall use EAP-TTLS SSID2 shall use EAP-TLS (high-secured Net like personal Data) what logic starts the right inner-EAP-Protocol, cause neither the AccessPoint(WLAN-Controller), nor the radius server know, what Method to use, when there are many enabled. e.g. on a cisco-Radius, that runs with enabled PEAP and TLS, but there's no special attribute defined to control that thanks for reply, Rainer Brinkmann University-Clinicum Hamburg / Germany

Re-write Attributes based upon NAS-Port-Type and LDAP authorization response
by Bill Carr 26 Jun '06

26 Jun '06

Hello Folks, I've posted something similar to this in the past and my question was answered rather tersely. I'm hoping a little more detail will invoke the type of kind responses I'm used to in the Open Source Community. I've got FreeRadius on RedHat ES3 authenticating users to OpenLDAP. So far we've simply been authenticating users via 802.1x on Wired Switch ports and we've now added new equipment for WIFI which requires the RFC3580 attributes (instead of the Filter-ID we've populated in our LDAP schema). I believe it should be relatively simple to perform the following check's to "re-write" my attributes for the WIFI Gear. I can base the decision to re-write on the NAS-Port-Type received. My pseudo-code thought process is outlined below (I'm not a coder, would never profess to be; thus my post!): if NAS-Port-Type == "Wireless - IEEE 802.11" then Tunnel-Medium-Type == IEEE-802 Tunnel-Type == VLAN if Filter-ID =~ "Internet-Restricted" then Tunnel-Private-Group-ID == 155 (or the Restricted VLANID) elseif Filter-ID =~ "Allow-All" then Tunnel-Private-Group-ID == 156 (or the Allowed VLANID). endif endif My reading thus far has lead me to test my reply attribute requirements from the "users" file and that works perfectly. If someone could point me in a simple direction on how to strip/rewrite the attributes based on the 'authorization' reply from LDAP, I'd be indebted. I've seen examples of profiles stored on LDAP, but I'm curious how I could choose a different profile based upon the "NAS-Port-Type" received in the Access-Request Here's what I did in the "users" file to test successfully (I don't know that it's of any value but to demonstrate what I'm trying to accomplish). testuser User-Password == "user", NAS-Port-Type == "Wireless-802.11" Tunnel-Medium-Type == "IEEE-802", Tunnel-Type == "VLAN", Tunnel-Private-Group-Id == "155" testuser User-Password == "user", NAS-Port-Type == "Ethernet" Filter-ID == "Enterasys:version=1:policy=Internet-Restricted" admin User-Password == "admin", NAS-Port-Type == "Wireless-802.11" Tunnel-Medium-Type == "IEEE-802", Tunnel-Type == "VLAN", Tunnel-Private-Group-Id == "156" admin User-Password == "admin", NAS-Port-Type == "Ethernet" Filter-ID == "Enterasys:version=1:policy=Allow-All" Thanks to all in advance.

RE: Malfunctioning Nomadix
by Rob Parker 26 Jun '06

26 Jun '06

Hi, I've seen this with our Nomadix USG and AG series devices as well - often the NSE will send requests multiple times, but I can never understand why. There are a few other bugs in the RADIUS code in Nomadix as well, for example I have never managed to get round robin working as I would expect (50% to each server). With our RADIUS setup the multiple stop or start packets do not cause any problems as the session ID is unique so a duplicate cannot be inserted into our accounting database. I am in discussions with developers at Nomadix at the moment about stability issues, and I have also mentioned these RADIUS issues to them as well - hopefully they will be fixed soon! Which devices and firmware versions do you have this problem with? rob. -----Original Message----- From: Santiago Balaguer García [mailto:santiagoawa@hotmail.com] Sent: 22 June 2006 12:48 To: freeradius-users(a)lists.freeradius.org Subject: Malfunctioning Nomadix Hi, I have a possible bug in Nomadix devices but I am not sure and it is a RADIUS problem. These hotspots normally works fairly, however some of them sometimes have a strange behavior. Nomadix sends more then one authentication requests to RADIUS server for disconnecting. It write the same entry several times in my DB, this fact corrupts my stadistics. I send you several accounts in the attachment with this case in a same hotspot Nomadix. _________________________________________________________________ ¿Estás pensando en cambiar de coche?

Problems with Redundant Proxy config with FreeRadius 1.0.1-2.FC3.1 (Fedora Core 3)
by Shaun Mccullagh 26 Jun '06

26 Jun '06

Hi, I would like FreeRadius to proxy requests to two radius servers. Normally requests should go to a primary(kiezel1i), but if this is unavailable it should send requests to a secondary(kiezel2i). I'm using the config at the bottom of this message. If I shut the primary down, FreeRadius never forwards the requests to the secondary. Have I made a mistake in my config? How does FreeRadius determine if the Primary is unavailable? TIA Shaun proxy server { synchronous = no retry_delay = 5 retry_count = 3 dead_time = 180 default_fallback = no post_proxy_authorize = yes } realm LOCAL { type = radius authhost = LOCAL accthost = LOCAL } realm NULL { type = radius authhost = LOCAL accthost = LOCAL } realm erbi.nl { type = radius authost = LOCAL acchost = LOCAL } realm zzl-ra.nl { type = radius authhost = kiezel1i:1812 accthost = kiezel1i:1812 secret = xxx ldflag = fail_over } realm zzl-ra.nl { type = radius authhost = kiezel2i:1812 accthost = kiezel2i:1812 secret = xxx ldflag = fail_over } Op dit e-mailbericht is een disclaimer van toepassing, welke te vinden is op http://www.xb.nl/disclaimer.html

Re: So how do you suppress
by Walter Reynolds 26 Jun '06

26 Jun '06

So what 'rest of the documentation' should I look at. I guess I am not seeing how I should know that the "auth_log" is a variant of the "detail" module. I am hoping i can get a better understanding of the documentations so I would not have to ask questions in the future. So for this example I saw the following: 1. Note in changelog about suppress 2. Section under 'detail' in radiusd.conf file with supress option commented out. So I now understand that I should be able to suppress information from any of the detail sections by adding an additional suppress line under that module subsection. Is this something that I should have understood to start with or is there documentation that I did not see and should read? ===================== Date: Fri, 23 Jun 2006 11:11:21 -0400 From: "Alan DeKok" <aland(a)nitros9.org> Subject: Re: Freeradius-Users Digest, Vol 14, Issue 95 To: FreeRadius users mailing list <freeradius-users(a)lists.freeradius.org> Message-ID: <20060623151121.6DF4216E49(a)mail.nitros9.org> Walter Reynolds <waltr(a)umich.edu> wrote: > Now the question is what example config file had the suppress stanza under > the detail auth_log section as well?

You should define >them better in order to get help from the list. My goal is to replace VPN server, based on win2003, with FreeBSD one. WIN 2003 can do 1 and 2 in my questions, so I have to realize how to setup this in mpd + freeradius. I already authenticate users from AD group: ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{Stripped-User-Name:-%{User-Name:-None}} --challenge=%{mschap:Challenge:-00} --nt-response=%{mschap:NT-Response:-00} --require-membership-of=EXAMPLE+VPN_Allowed". But I have several vpn groups and need to setup timeouts on each one. Also I need to I assign specific IP for specific user in AD. Looks like FreeRadius should respond for this. -----Original Message----- From: Nikos Vassiliadis [mailto:nvass@teledomenet.gr] Sent: Monday, June 26, 2006 2:22 PM To: freeradius-users(a)lists.freeradius.org Cc: Егоров Сергей Subject: Re: mpd+freeradius+AD On Monday 26 June 2006 09:55, Егоров Сергей wrote: > Hi all!

So, if you want different rules for different usernames ipfw is the sensible packet filter to use. You can find the radius section of mpd, here: http://www.bretterklieber.com/mpd/doc4/mpd28.html Your questions don't clearly tell where your problem is. Active Directory? mpd? or FreeRADIUS?

Hi all! I have completed setup of mpd+freeradius+AD 2003. Now my users authenticating from Active Directory, if they are members of specific group. But I still have some questions: 1. How to make a different timeouts for different groups in AD 2. How to appoint special IP for special users 3. How to restrict users to access only to defined IP in my network

LDAP(Active Directory) password AND groups not working together
by duckeo 26 Jun '06

26 Jun '06

I'm pretty sure the problem lies in my interpretation of the users file documentation, but I'm now stuck. The aim is to authenticate users to their MS active directory account via LDAP, and then check that the user is a member of the WirelessVPN group -- if these two conditions meet then the user is granted access. What's happening at the moment is as long as the user EXISTS the authentication will pass, even if the password is incorrect. If the useraccount does not exist it will fail. Output from debug during a CORRECT username but INCORRECT password (blablalba): rad_recv: Access-Request packet from host 10.200.148.49:3678, id=81, length=50 User-Name = "radiustest" User-Password = "blablabla" Processing the authorize section of radiusd.conf modcall: entering group authorize for request 4 modcall[authorize]: module "preprocess" returns ok for request 4 rlm_ldap: - authorize rlm_ldap: performing user authorization for radiustest radius_xlat: '(&(sAMAccountname=radiustest)(objectClass=person))' radius_xlat: 'OU=Domain Users,DC=foo,DC=bar,DC=foo,DC=bar' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in OU=Domain Users,DC=foo,DC=bar,DC=foo,DC=bar, with filter (&(sAMAccountname=radiustest)(objectClass=person)) rlm_ldap: looking for check items in directory... rlm_ldap: looking for reply items in directory... rlm_ldap: user radiustest authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns ok for request 4 modcall[authorize]: module "chap" returns noop for request 4 modcall[authorize]: module "mschap" returns noop for request 4 rlm_realm: No '@' in User-Name = "radiustest", looking up realm NULL rlm_realm: No such realm "NULL" modcall[authorize]: module "suffix" returns noop for request 4 rlm_eap: No EAP-Message, not doing EAP modcall[authorize]: module "eap" returns noop for request 4 rlm_ldap: Entering ldap_groupcmp() radius_xlat: 'OU=Domain Users,DC=foo,DC=bar,DC=foo,DC=bar' radius_xlat: '(&(objectClass=group)(member=CN=Test\\, Radius,OU=testing,OU=Domain Users,DC=foo,DC=bar,DC=foo,DC=bar))' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in OU=Domain Users,DC=foo,DC=bar,DC=foo,DC=bar, with filter (&(cn=RadiusWirelessVPN)(&(objectClass=group)(member=CN=Test\\, Radius,OU=testing,OU=Domain Users,DC=foo,DC=bar,DC=foo,DC=bar))) rlm_ldap::ldap_groupcmp: User found in group RadiusWirelessVPN rlm_ldap: ldap_release_conn: Release Id: 0 users: Matched entry DEFAULT at line 216 modcall[authorize]: module "files" returns ok for request 4 modcall: group authorize returns ok for request 4 rad_check_password: Found Auth-Type Accept rad_check_password: Auth-Type = Accept, accepting the user radius_xlat: 'You are now connected FooBar Network.'
