case-statement regex
by O'Connell, Ryan 07 Jan '16

07 Jan '16

Using version 3.0.10. Can’t seem to implement regex matching with case statements. The request always results in “def” even though the string in the request contains “abc". switch DHCP-Subscriber-Id { case "/(abc)$/" { update control { &Pool-Name := “abc" } } case { update control { &Pool-Name := “def" } } } I have tried a bunch of different variations of the “case” without success. If I use the entire string in the case statement then I get the intended result “abc”. switch DHCP-Subscriber-Id { case 001122334455@abc { update control { &Pool-Name := “abc" } } case { update control { &Pool-Name := “def" } } } Does anyone have a suggestion on how to implement this? I haven’t been able to find examples in the documentation or google about doing this specifically. The same logic implemented with if/else works fine but I was hoping to use switch/case for performance. if (&DHCP-Subscriber-Id =~ /(abc)$/){ update control { &Pool-Name := “abc" } } else { update control { &Pool-Name := “def" } } Thanks, Ryan

RE: Safe characters, old and new versions of 3.1.0

Thanks Alan, that's really useful info, especially the fix - makes good sense. I was doubtful about the older server and what was written to SQL whether it was actually right or not, so this seems better anyway. I've never seen a date expressed with backslashes, dashes yes, forward slashes yes, but backslash is umm, different. Again, thanks very much.

Is there any way of replicating old behaviour or fixing the new? Re-write the date string in FreeRADIUS so that it uses forward slashes instead of backslashes. The easiest way to do this might be to use a regular expression. to parse the string into chunks, and the re-assemble the chunks: if (&control:Ldap-UserDescription =~ /(..).(..).(....)$/) { update control { Ldap-UserDescription := "Amended by Directory Manager %{1}/%{2}/%{3}" } } The simple lesson is "don't use backslashes". The third-party system you're using is broken. Happily, you should be able to fix it with FreeRADIUS. Alan DeKok. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

proxy implementation
by srithar jeevadurai 07 Jan '16

07 Jan '16

Dear Friends, We have successfully implemented NAS <--> FreeRadius <--> IN However now we have to implement NAS <--> Proxy (auth + acct) <--> FreeRadius <--> IN Can you please help me on the same? When we tried, proxy server is giving below error message. 1. *Auth: Login incorrect: [newhostt(a)domainserver.com <testhost(a)server.com>] (from client 222.222.222.90 port 16634 cli 3455534333)* Proxy server is trying to validate the user however as per my understanding, it has to forward to home server instead of validating the user. Please let me know if you need any configuration files to be uploaded, I will send the same in the email. 1. Proxy server does not obtain persistent connection to home servers and the connection is only when it forwards request (auth or act) home server. Is our understanding correct? because We are doubt that proxy server is connecting to home server or not. -- Regards, Srithar Durairaj Alternate Mail I.D: srijeevadurai1(a)yahoo.co.in Mobile: +919886251852

Safe characters, old and new versions of 3.1.0
by Franks Andy (IT Technical Architecture Manager) 07 Jan '16

07 Jan '16

Hi all, Sorry to post so much, struggling with differences again in the newer version of FR I have on a server. The older is 3.1.0 git #390f216, the newer 3.1.0 git #f4d5ff6. We're seeing differences in the way unusual characters are handled in the older version when compared with the newer, in terms of the way variable values with certain characters are expanded. The main problem is it mucks up the SQL character writing - the frontend comes up with an odd asci character that in theory shouldn't be written according to the "safe characters" list afaics. I can't change what's in the ldap description field we use as the source of this attribute unfortunately - a third party system writes into it which we have no change access to. Anyway, below are examples on old and new of the ldap attribute source, an example variable expansion of that attribute and lastly what goes into SQL. The examples aren't quite indentical as one is a live system that's so busy it's hard to get exactly the same string from it. Generally the string is "Amended by Directory Manager dd\mm\yyyy" in AD, but that comes over to ldap as dd\\mm?y for some reason, presumably because of weird characters in the string that look ok in AD console. What gets inserted after that into SQL is, on the old server, "Amended by Directory Manager dd(asciicode)mm(asciicode)yy" Which appears fine within mysql. On the new server "Amended by Directory Manager dd\\mm?y" plus some other non-visible stuff I guess, which isn't fine. In SQL is looks like a square box, not sure of the actual ascii code. This character doesn't seem to be part of the "safe characters". Also on the old server and new one, the ordinary backslash makes its way through to sql but I can't see it on the SC list. Any ideas?! Is there any way of replicating old behaviour or fixing the new? Thanks Andy Old server (35) ldap3: control:Ldap-UserDescription := 'Amended by Directory Manager 26\\08?5' Variable expansion (35) EXPAND %{control:LinelogString}, DESC: %{control:Ldap-UserDescription} (35) --> 07-01-2016 11:13:51, WEBSTERC(a)SATH.nhs.uk, Accept, DESC: Amended by Directory Manager 26\\08\2015 Sql config: safe_characters = "@abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.-_: /" Insert 'Amended by Directory Manager 26=5C08=815' New server (10) ldap5: control:Ldap-UserDescription := 'Amended by Directory Manager 02\\12?4' Variable expansion (10) EXPAND %{control:LinelogString}, DESC: %{control:Ldap-UserDescription} (10) --> 07-01-2016 10:48:56, franksa, Accept, DESC: Amended by Directory Manager 02\\12\2014 '%{control:Ldap-UserDescription}' Sql config: safe_characters = "@abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.-_: /" Insert Amended by Directory Manager 02\\12?4'

>Hi, > TBH, iu cant recall if expansions work for that section in radiusd.conf - if theres a quirky bug it wont get fixed in 2.1.12 Our Ubuntu server setup uses packages from http://packages.ubuntu.com using apt-get, they are still providing v2.1.12 and they have not changed to v3 yet. Not sure why Ubuntu support have not updated the packages for customers when its out of date.... >but for logging there are 2 ways that do work....and should work fine >1) use the 'detail' module >2) use linelog The detail log is not really what I want. I just want to record requests. It is working for 'default' and 'inner-tunnel' but nothing else :( I tried the linelog method, and that didn't work either. No logs generated. I am not even sure that detail logging is working either. There are a couple of old log files in the radacct directory but nothing newer. >for the details module - i think you are using this(!) ? you should be looking at modules/detail.log file - as thats the file that is actuslly >used for auth_log et al >and if %{Virtual-Server} expansion doesnt work there - easy, just create a new detail entry eg >eduroam_auth_log and call that instead of auth_log in relevant section of the virtual server - and do the same for the other calls to log >functions >eg >detail eduroam_auth_log { > detailfile = ${radacctdir}/%{%{Packet-Src-IP-Address}:-%{Packet-Src-IPv6-Address}}/auth-detail-%Y%m%d > detailperm = 0600 > suppress { > User-Password > EAP-MSK > EAP-EMSK > EAP-Message > MS-MPPE-Recv-Key > MS-MPPE-Send-Key > MS-MPPE-Encryption-Policy > MS-MPPE-Encryption-Types > } } > ..for linelog, simply look at the modules/linelog file and configure as required....or make a new one eg >linelog eduroam-linelog { ><put config here!> >} > and then call linelog in relevant place to capture required bits - linelog is generally better as the output can be nicely customised to >contain exactly the stuff needed in format needed... I tried this method, freeradius -X started up ok. But no logs generated... I am stuck at this point. >obviously there are many other methods - eg using the buffered-sql virtual server and copying detail output asynchronously to an SQL server so >you have logs in database format (great for searching) >some of this may only be applicable to 2.2.x - but thats what you should be running as a minimum these days (and even that is around end of >support time) Any other ideas?

Fwd: FreeRADIUS + Cisco + Active Directory
by Rashad Hall 06 Jan '16

06 Jan '16

I am pretty sure my approach to this is all wrong so I've decided to seek the help of the experts. I have configured a FreeRADIUS server that authenticates our wifi users with EAP-TLS and will also authenticate users for our network devices. Our network devices are mainly Cisco and I need these devices to authenticate users based on their Active Directory credentials. Wifi portion is complete, but having trouble with using FreeRADIUS to check AD credentials correctly. I decided to use MSCHAP (my mistake I believe) for Authentication and my "radtests" are successful, but when trying to log into a switch I set up for testing I am unsuccessful. I believe the switch only uses PAP and does not have the capability to use MSCHAP but I am unsure of how to set up PAP to query AD or somehow convert the PAP request into an MSCHAP request server side. Can anyone tell me the best most secure approach to accomplishing my goal (if possible, I must suck at Googling)? In the future I'd also like to assign Cisco priv levels based on groups a user belongs to in AD. Below is debug output showing first a successful radtest and then the unsuccessful login into the switch. radiusd -X Copyright (C) 1999-2015 The FreeRADIUS server project and contributors There is NO

Freeradius logging problem
by Peter Hutchison 06 Jan '16

06 Jan '16

I was wondering if you could help use with our eduroam setup at the University of Huddersfield? We have set up Freeradius on Ubuntu 14.04 LTS but having trouble to get it to generating authorization logs for our 'eduroam' virtual server. It is generating logs ok for the default and inner-tunnel but not eduroam. I have checked and re-checked the configuration with no result. /etc/freeradius/radius.conf log section looks like this: prefix = /usr exec_prefix = /usr sysconfdir = /etc localstatedir = /var sbindir = ${exec_prefix}/sbin logdir = /var/log/freeradius raddbdir = /etc/freeradius radacctdir = ${logdir}/radacct log { destination = files file = ${logdir}/radius.log requests = ${logdir}/radiusd-%{%{Virtual-Server}:-DEFAULT}-%Y%m%d.log ... } And in our eduroam file in sites-available (with link file in sites-enabled) has 'auth_log' enabled to in the authorize section. It should create logs called radiusd-eduroam-20151217.log but nothing is being created. Logs are a requirement for a valid eduroam setup and this is the last thing needed before we can switch over to the new servers. Any ideas why the log isn't being generated when users connect to it?

Thanks and goodbye

Many years ago we started out with Cistron Radius and then migrated to FreeRadius when it became available. The only thing we have used radius for is dial-in authentication. While Cistron worked fine for that, I had to hack it numerous times to be able to support the local site policies. FreeRadius made that really easy. Modules are cool. However, we no longer have enough dial-in users to justify keeping the service and are doing away with it in a few weeks. So, I wanted to thank Alan and all the others who have provided help and information to us over the years. It's a great product. — Doug

[LDAP] access to attribut with unlang
by vince technical address 06 Jan '16

06 Jan '16

Hi, I currently use the rlm_ldap module to retrieve an entry corresponding to a filter defined in the authorize section. After (but always in section authorize) I would use the value of an LDAP attribute recovered with unlang. Is it possible ? Example : authorize { ldap if(attribute == "qwerty") { reject } } With "attribute"is the value of the attribute has been recovered with module ldap. (it is an idea to overcome the fact that xlat ldap does not enable failover). Thanks Vince
