NAS sql

hi, any reason why the NAS schema is not part of the database schema? nas.sql and schema.sql rather than just schema.sql? alan

postgres accounting schema
by A.L.M.Buxey＠lboro.ac.uk 11 Apr '08

11 Apr '08

hi, I wonder how many of you have needed to change the postgres schema for radacct table - the default value of VARCHAR(32) for the AcctSessionId seems to be very low - our user-names are often that long by themselves! (domain and full path when using machine auth for example) I've submitted a patch via the bugs system to put this up to something safer. perhaps time that we all peer through the current supplied values and what we are each using after we've fixed things? If others can start with sane values (no matter if its MySQL, PostgresQL, Orcale etc) then that can only be a good thing for our community. There was also talk about certain indexes and procedures recently. alan

Hello Debug is difficult because of Segmentation Fault. I will try to rebuild radius (in the night) with last patch , that you already provide. Is It something wrong whth my configuration? I decide to disable all nonused modules. Maybe I disable something major? root@aaa# radiusd -X FreeRADIUS Version 2.0.4, for host i686-pc-linux-gnu, built on Apr 7 2008 at 10:36:05 Copyright (C) 1999-2008 The FreeRADIUS server project and contributors.

FR 2.0.3 gives duplicate NULL realm error
by John Horne 11 Apr '08

11 Apr '08

Hello, I have been running FR 2.0.2 (built from source) for a short while with no problems. I have now upgraded to 2.0.3 (built from Fedora 9 source RPM). When I try and start radiusd (using 'radiusd -X' I get the following error: realm NULL { /etc/raddb/proxy.conf[107]: Duplicate realm "NULL" } # realm NULL I have thoroughly checked the files, and there is no duplicate of the NULL realm. The end part of proxy.conf contains the NULL realm, and it is configured as: home_server_pool local_proxies { type = fail-over home_server = IAS-1 home_server = IAS-2 home_server = ILS009 } [other home server pools and realms defined] realm NULL { auth_pool = local_proxies } I'm not sure why the 'radiusd -X' output gives as the very last line '} # realm NULL'. As can be seen in proxy.conf, the very last line has no comment attached to it. Anyone any ideas about why radiusd is complaining about a duplicate NULL realm? Thanks, John. -- --------------------------------------------------------------- John Horne, University of Plymouth, UK Tel: +44 (0)1752 233914 E-mail: John.Horne(a)plymouth.ac.uk Fax: +44 (0)1752 233839

Problem with LDAP module in 2.0.3 -- Ldap-UserDn unavailable
by Jason Alderfer 11 Apr '08

11 Apr '08

I'm testing upgrading from 1.1.7 to 2.0.3 and have run into a problem with the LDAP module. The problem appears in 2 places. First, I'm using the --with-edir option so I have password_attribute = nspmPassword and edir_account_policy_check = yes set. However, in 2.0.3, when I set "edir_account_policy_check = yes", I get this error: +- entering group post-auth rlm_ldap: User's FQDN not in config items list. ++[ldap] returns fail PEAP: Tunneled authentication was rejected. rlm_eap_peap: FAILURE If I don't set edir_account_policy_check, then authentication is successful, but the second problem shows up. A little background: In 1.1.7 I'm setting VLANs via the 'users' file like this: DEFAULT Ldap-UserDn =~ "ou=is,ou=n,o=emu" Tunnel-Type = "VLAN", Tunnel-Medium-Type = "IEEE-802", Tunnel-Private-Group-Id = 3 and I've tried this in 2.0.3, but I've also tried unlang if (Ldap-UserDn =~ /ou=is,ou=n,o=emu/i) { update reply { Tunnel-Type := "VLAN" Tunnel-Medium-Type := "IEEE-802" Tunnel-Private-Group-Id := 3 } } Neither of these work in 2.0.3. The VLAN does not get set. Files returns noop, and unlang shows in debug output ++? if (Ldap-UserDn =~ /ou=is,ou=n,o=emu/i) (Attribute Ldap-UserDn was not found) I did some digging and I think I know why this is. In rlm_ldap.c beginning at line 1306 is /* * Adding new attribute containing DN for LDAP object associated with * given username */ pairadd(check_pairs, pairmake("Ldap-UserDn", user_dn, T_OP_EQ)); However, in 1.1.7 the code is pairadd(&request->packet->vps, pairmake("Ldap-UserDn", user_dn, T_OP_EQ)); If I add this line to 2.0.3 just after the existing pairadd line and recompile, then everything just works -- edir policy check works and I can set VLANs using files module or unlang. Is this a bug in 2.0.3 or am I missing something in my new config file that would make the Ldap-UserDn available? Jason

libpam-radius-auth password problem
by Fabio Pedretti 11 Apr '08

11 Apr '08

I am trying to configure a linux machine (Ubuntu 8.04 alpha, 32 bit) with radius authentication using libpam-radius-auth. I installed freeradius-2.0.3 (from selfbuilded deb package) on the same machine and added this line at the top of users file: testuser Cleartext-Password := "testing" Then I installed libpam-radius-auth 1.3.17-0ubuntu1 from the ubuntu repositories. I added the radius entry in /etc/pam.d/sshd: [...] auth required pam_env.so envfile=/etc/default/locale auth sufficient pam_radius_auth.so debug # Standard Un*x authentication. @include common-auth [...] and this on pam_radius_auth.conf: # server[:port] shared_secret timeout (s) 127.0.0.1 testing123 1 When I try to authenticate with ssh into the machine I noticed that freeradius receive this password "\010\n\r\177INCORRECT", that it's not the one I typed. This is the output of auth.log: Mar 18 18:05:59 test sshd[2533]: pam_radius_auth: Got user name testuser Mar 18 18:05:59 test sshd[2533]: pam_radius_auth: Sending RADIUS request code 1 Mar 18 18:05:59 test sshd[2533]: pam_radius_auth: DEBUG: getservbyname(radius, udp) returned -1211761632.

Testig with radtest works fine. I noticed a similar problem some time ago, that seemed to be related to 64 bit machines: http://lists.cistron.nl/pipermail/freeradius-users/2006-August/055877.html However I am using a 32 bit machine on an updated system. Where could be the problem? Thanks, Fabio
