Adding a realm to username with pam_radius_auth
by Walter Goulet 23 Nov '05

23 Nov '05

Hi, Quick question regarding pam_radius_auth. Since you have to have a local account on the client machine using pam_radius_auth to authenticate ssh sessions, how would you go about adding a realm to the username portion of the authentication request? Reason I'm asking is because I'd like to use pam_radius_auth on a client machine that talks to a AAA proxy server. The proxy server needs to use the realm name to figure out which AAA server to route the request to. Can I specify this with the client-id option in the pam_radius_auth configuration file? Thanks, Walter

parsing detail files myself
by Ming-Ching Tiew 22 Nov '05

22 Nov '05

As a follow on the my requirement of reading the detail file and updating them into MSSQL database, I have written a program to parse the content of the file, which is produced by ***ONE*** single Cisco box sending data to free radius 1.04, and this is what I noticed, I need someone to tell me if this is an expected behaviour or somewhere there is something wrong :- My observations :- 1. The number attributes in a records ( ie the number of lines in a "record" ) is not consistent. I have skipped those Cisco-AVPair in the files, and this is the stats :- acount=25, value=0 acount=26, value=0 acount=27, value=0 acount=28, value=0 acount=29, value=14 acount=30, value=16 acount=31, value=7290 acount=32, value=6724 acount=33, value=0 acount=34, value=0 acount=35, value=0 In other words, in my detail file, there are 14 records which have 29 attributes, 16 records with 30 attributes, 7290 records which have 31 attributes and 6724 records with 32 attributes. Question is why don't they have the same number of attributes ? 2. Not only that, the occurances of the attributes are not consistent either :- attrib=Acct-Authentic, occurance=14043 attrib=Acct-Delay-Time, occurance=14043 attrib=Acct-Input-Octets, occurance=14043 attrib=Acct-Input-Packets, occurance=14043 attrib=Acct-Output-Octets, occurance=14043 attrib=Acct-Output-Packets, occurance=14043 attrib=Acct-Session-Time, occurance=14043 attrib=Acct-Status-Type, occurance=14043 attrib=Acct-Unique-Session-Id, occurance=14055 attrib=Called-Station-Id, occurance=14043 attrib=Calling-Station-Id, occurance=14013 attrib=Cisco-NAS-Port, occurance=6194 attrib=Client-IP-Address, occurance=14045 attrib=NAS-IP-Address, occurance=14043 attrib=NAS-Port, occurance=6194 attrib=NAS-Port-Type, occurance=6194 attrib=Service-Type, occurance=14043 attrib=Timestamp, occurance=21349 attrib=User-Name, occurance=14013 attrib=gw-final-xlated-cdn, occurance=545 attrib=gw-rxd-cdn, occurance=14043 attrib=h323-call-origin, occurance=14043 attrib=h323-call-type, occurance=14043 attrib=h323-conf-id, occurance=14043 attrib=h323-connect-time, occurance=14043 attrib=h323-disconnect-cause, occurance=14043 attrib=h323-disconnect-time, occurance=14043 attrib=h323-gw-id, occurance=14043 attrib=h323-incoming-conf-id, occurance=14043 attrib=h323-remote-address, occurance=7849 attrib=h323-setup-time, occurance=14043 attrib=h323-voice-quality, occurance=14043 attrib=session-protocol, occurance=7849 attrib=subscriber, occurance=14043 Take for example, why Cisco NAS port has such low occurances in the detail file ? Similarly why h323-remote-address has such a low occurances ? Is it a Cisco thingy or free radius did not parse what Cisco sent correctly ? Appreciate any help or comments.

Freeradius How to integrate Active Directory [AD Integration WindowsXP NTLM Tutorial]
by charles schwartz 22 Nov '05

22 Nov '05

Hi list, A lot of people on this list would like to integrate Active Directory with FreeRADIUS in order to provide a transparent user authentication login process. There are at least 2 ways to integrate AD: LDAP and NTLM. I've written a tutorial about how to do this with NTLM (winbind, ntlm_auth). The Windows supplicants are configured to work with PEAP and MSCHAPv2. You can download it from here: http://homepages.lu/charlesschwartz/radius/freeRadius_AD_tutorial.pdf Good luck!

ntlm_auth problem
by Andrew Dixon 22 Nov '05

22 Nov '05

Hi All. I have setup up a VPN server using FC4 and Poptop using freeradius for authication via a Windows DC. As far as I can see everything is setup correctly, however it fails to authicate any users when a login attempt is made. It is logging the following error message in the radius.log file: Tue Nov 22 22:01:47 2005 : Error: Exec-Program: FAILED to execute /usr/bin/ntlm_auth: Permission denied I have checked the permissions on this file and everyone has permission to execute it and if I execute it manually from the command prompt I can authicate users without issue. Anyone have any ideas what the problem could be. Thanks in advanced. Andrew.

Password Expiry policy
by Alhagie Puye 22 Nov '05

Hello all, I was wondering if anyone has implemented the feature of password expiry with Freeradius used for authenticating Cisco VPN clients. I have a Cisco PIX firewall using Freeradius as a backend (/etc/passwd). Anyway help would be greatly appreciated.

Hi all, I have configured freeradius over RedHat AS4, mysql and dialup admin. I'm still now in testing phase. When testing an account with ntradping utility I get the following log on radius.log: Tue Nov 22 18:02:26 2005 : Error: rlm_sql: Failed to create the pair: Unknown value Local for attribute Auth-Type Tue Nov 22 18:02:26 2005 : Error: rlm_sql (sql): Error getting data from database Tue Nov 22 18:02:26 2005 : Auth: Login OK: [test/123] (from client flaifel port 0) On ntradping I get access accept and I can see the attributes, but is there any error in the log ?? or its normal ? Regards, Flaifel

freeradius SIGSEGV, Segmentation fault.
by Norbert Wegener 22 Nov '05

22 Nov '05

I want to do machine authentication against an AD and grabbed the latest version from cvs this morning. I configured and ran it, but during establishing the connection, freeradius segfaults. The last lines are: rlm_eap_tls: Received EAP-TLS ACK message rlm_eap_tls: ack handshake is finished eaptls_verify returned 3 eaptls_process returned 3 rlm_eap: Freeing handler modcall[authenticate]: module "eap" returns ok for request 7 modcall: leaving group authenticate (returns ok) for request 7 Sending Access-Accept of id 107 to 111.222.36.124 port 1645 MS-MPPE-Recv-Key = 0x6b1b534ccd84a4f094b930849e651c507bf054567863aa80992384accc184dfc Segmentation fault The complete run under gdb can be found at http://www.wegener-net.de/fr/, where bt.txt contains the ouput of gdb (not too much). Additionaly I have put the config files there. Norbert Wegener

Access-challenge & attributes
by MINODIER David RD-RESA-LAN 22 Nov '05

22 Nov '05

Hi all, I'm using EAP-MD5 to authenticate a user. Freeradius eventually returns an access-accept packet, the user is authenticated, no pb. However, i have this question: Is it "normal" that the attributes contained in the access-accept packet are also contained in the Access-Challenge packets sent by Freeradius ? Is there a way to force Freeradius to return the attributes associated to the user in the access-accept packet only ? Many thanks. David

Does a tool exist, that lets me test machine account authentication against an AD? Something like an equivalent to radtest? Thanks Norbert Wegener
