Multiple LDAP searches
by Rob Brickhouse 31 Mar '10

31 Mar '10

I am setting up freeradius 2.1.6 and seem to be stuck on how do I go about setting up my ldap module to search multiple basedn if the user is not found in the first? I have four that I need to search in my LDAP tree but cannot figure out the correct way to make it search more than one. I feel like this is probably something simple I'm missing but can't seem to see it atm. Thanks Rob

Overriding Auth Type in Post Auth
by Johan Meiring 31 Mar '10

31 Mar '10

Hi, In another recent email Alan mentioned that you cannot override a reject in Post-Auth >> post-auth { >> > Post-Auth-Type REJECT { >> > # attr_filter.access_reject >> > Auth-Type := Accept >> > } >> > } > > It's too late to over-ride the reject at that point. I want to implement something differently. I want to override an Accept to a Reject in post-auth (using rlm_perl). I got the impression from another email that that is possible. >> >> >> I basically want freeradius to do the PAP/CHAP stuff and AFTER that I >> want to do things like check the users CAP. > > Use post-auth. The way this sounds, is that you can change an Accept into a Reject, but not the other way around in post-auth. Or am I confused?

Re: Converting attributes from hex to ASCII
by Aaron Paetznick 31 Mar '10

31 Mar '10

Thanks Arran, but I'm already pretty clear on how to update variables in the request. I just don't know how to go about adding the logic to convert hex/octal strings to ASCII values in unlang. This is untested, but my current line of thinking is to modify the queries in sql.conf with something like this: ... IF('%{Some-Trigger-Attribute}'="TRIGGER-VALUE", UNHEX('%{Called-Station-Id}'), '%{Called-Station-Id}'), \ ... A little bit of overhead to every query, but I suspect it will be manageable on our network. Alternatively, I suppose I could do something like this (untested): ... if ("%{Some-Trigger-Attribute}" =~ /^TRIGGER-VALUE$/) { update request { Called-Station-Id := '%{sql:SELECT UNHEX(%{Called-Station-Id})}' } } ... This somehow seems less desirable though. --Aaron On 3/30/2010 10:06 PM, Arran Cudbard-Bell wrote: > update request { > Tmp-String-1 := `printf etc...` > } > > Then use variable expansion %{request:Tmp-String-1}.

Question: How do I forcibly accept all rest requests??
by Difan Zhao 31 Mar '10

31 Mar '10

Good afternoon guys! I am running version 2.1.6. The server is currently doing 802.1x authentication for network devices. Some devices are PCs and users use their Windows domain user/password to login. The rest are special network equipments and I use "MAC address authentication bypass" to authenticate them. Now I have a dilemma that I need to make all other devices (guest devices from out of my company) to be authenticated as well... Currently if these devices (usually laptop running Windows XP) support 802.1x, they will fail and they will be put in an Auth-failed VLAN. The VLAN itself is fine and they can do whatever they want on this VLAN. However it's just that annoying icon on their laptops. It pops up from time to time to notify users that they failed authentication and even prompted for username and password if configured to do so... So I want to make all rest devices to be authenticated. It will be even better if I can assign them to a specific VLAN. I was reading ./sites-avaliable/default and I found that "forcibly accept the user (Auth-Type := Accept)". Where do I put it? I tried: post-auth { Post-Auth-Type REJECT { # attr_filter.access_reject Auth-Type := Accept } } And obviously it's not working... Any ideas how I should configure it? Thank you!

acct-session-id
by Marlon Duksa 31 Mar '10

31 Mar '10

Hi - The acct-session-id attribute has the length defined as =>3 in RFC 2059. Is anyone aware of any practical limitations on the length of this attribute? Does FreeRadius support the length of this attribute to be let say 300bytes, and are you aware of any other Radius servers that may have problem with larger lengths? Thanks, Marlon

Converting attributes from hex to ASCII
by Aaron Paetznick 30 Mar '10

30 Mar '10

I am receiving certain accounting attributes as hex encoded strings, and I would like to convert them back to cleartext ASCII before sending them to MySQL. I can't simply update the SQL with UNHEX() functions, as not all of the requests are hex encoded this way. If I could use perl, I would do something like this: preacct { if ("%{SomeAtribute}" =~ /^MATCHING\:(.+)\:MATCHING$/) { update request { Calling-Station-Id := s/([a-fA-F0-9]{2})/chr(hex(%{1}))/eg } } ... } Maybe I can simply flag these attributes somehow by prefixing them with "FLAG::", and use the MySQL IF() function to "post process" them with the UNHEX() function? Any help would be appreciated. Thanks! --Aaron

What does the NAS-Port mean?
by CaiMuzhang 30 Mar '10

30 Mar '10

Hello! See the packet info below: rad_recv: Access-Request packet from host 168.2.8.28 port 5001, id=142, length=121 User-Name = "licheng" EAP-Message = 0x0201000c016c696368656e67 Message-Authenticator = 0xb11d9a0d22d86cfb58038fe5832a9f9a NAS-IP-Address = 168.2.8.28 NAS-Identifier = "000fe281c738" NAS-Port = 268517377 NAS-Port-Type = Ethernet Service-Type = Framed-User Framed-Protocol = PPP Calling-Station-Id = "0006-5b28-47aa" Notice the NAS-Port = 268517377. It should represent the ID of the port, from which the packet is sent. But when I look up the MIB info of the switch, I can't find such an ID of the port. Instead, the base port number is another integer. How can I get this number (say 268517377) by SNMP?

Hi, I am using FR 2.1.1, for host x86_64, with LDAP 802.1x/WPA + OpenLDAP for wireless network access. I've found that some clients using EAP-PEAP using mainly Windows Vista sends notebook credentials despite that is disabled automatically use of credentials... There are a few log entries like as as follows Auth: Login incorrect (rlm_ldap: User not found): [QSARGENTINA\\amumenthaler] (from client UP-PVIII-VIII-Bis port 0 via TLS tunnel) Please could you help me to find a fix? Thanks in advance! -- -- Open Kairos http://www.sergiobelkin.com Watch More TV http://sebelk.blogspot.com Sergio Belkin -
