Authorization
by Stefan Adams 19 Dec '05

19 Dec '05

I have read all the man pages and /docs and am having a difficult time understanding the authorization. I keep wanting to write "if...elseif...else" stuff but I'm pretty sure that doesn't apply to FreeRADIUS config files. In the radiusd.conf there is documentation on how to use checkval to compare against caller-id. That's exactly what I want to do, but I can't figure out how to *use* it. Let's say I have 2 groups: students and faculty. I want to authorize authenticated members of the LDAP group cn=students,ou=Groups IFF their Access-Request Called-Station-ID =~ "/:StudentWLAN$/" I want to authorize authenticated members of the LDAP group cn=faculty,ou=Groups IFF their Access-Request Called-Station-ID =~ "/:FacultyWLAN$/" All my users are authenticated against LDAP. If the user enters the correct username/password (as accepted by LDAP), the user should be able to associate to the WLAN, but only to the WLAN of which he/she is allowed. Students can connect to the StudentWLAN; Faculty can connect to the FacultyWLAN. How would I configure the checkval module? Is it even necessary to use the checkval module? How would I conifgure the users file? Is the users file even necessary? Just to show what I've got config'd at the moment... Using the config below, I am able to successfully allow users to join the WLAN using WPA and EAP-PEAP from Windows XP SP2. But again, the user should not be able to join just any ol' LAN. If anyone has any experience with using checkval or doing caller-id type activities, I'd love to read how you did it! P.S. I don't know who to direct compliments to, but the FreeRADIUS code is probably the most beautifully structured source code I have ever read. It is SO easy to read and extremely consistent! It's phenomenal! And no, I can't answer my question myself just cuz I read the code... ;) But it's helped me to get this far!! authorize { # for WinXP, 802.1x, EAP-PEAP, MS-CHAPv2 preprocess eap files ldap checkval } authenticate { # for WinXP, 802.1x, EAP-PEAP, MS-CHAPv2 Auth-Type MS-CHAP { mschap } eap } modules { mschap { authtype = MS-CHAP use_mppe = yes require_encryption = yes require_strong = yes with_ntdomain_hack = no } ldap { <snip> } eap { default_eap_type = peap timer_expire = 60 ignore_unknown_eap_types = no cisco_accounting_username_bug = no md5 { } tls { private_key_password = <snip> private_key_file = /etc/1x/server.pem certificate_file = /etc/1x/server.pem CA_file = /etc/1x/root.pem dh_file = /etc/1x/DH random_file = /etc/1x/random include_length = yes } peap { default_eap_type = mschapv2 } mschapv2 { } } } I have NOTHING in users at this moment.

Problem : RadClient : no response from server for ID 77
by yao guoxian 17 Dec '05

17 Dec '05

I have installed FreeRadius 1.0.5 on the machine which has the Redhat 9 os. I entered" Radtest test test localhost 0 testing123" to check if i had installed FreeRdius correctly and just find the following message: Sending Access-Request of id 77 to 127.0.0.1:1812 User-Name = "test" User-Password = "test" NAS-IP-Address = redhat NAS-Port = 0 Re-sending Access-Request of id 77 to 127.0.0.1:1812 User-Name = "test" User-Password = "\002*\362\230y\233\002\221?\250\027x\027\370\3608" NAS-IP-Address = redhat NAS-Port = 0 .......

RADIUS packet did not have correct Message-Authenticator
by Norbert Wegener 17 Dec '05

17 Dec '05

I do an eap/tls authentication and after that an ad search. This works so far. But when setting the groupmembership in the ldap1 section, there are problems. I do not see the usual eap messages flying around, but nevertheless radius sends an Access-Accept: rlm_ldap::ldap_groupcmp: User found in group 515^M rlm_ldap: ldap_release_conn: Release Id: 0^M users: Matched entry DEFAULT at line 25^M modcall[authorize]: module "files" returns ok for request 0^M modcall: leaving group authorize (returns updated) for request 0^M rad_check_password: Found Auth-Type Accept^M rad_check_password: Auth-Type = Accept, accepting the user^M Sending Access-Accept of id 0 to 149.246.133.44 port 32770^M Tunnel-Type:0 = VLAN^M Tunnel-Medium-Type:0 = 802^M Tunnel-Private-Group-Id:0 = "Core1"^M Finished request 0^M On the client side, where I have eapol_test, I get an error: STA 00:00:00:00:00:02: Received RADIUS packet matched with a pending request, round trip time 0.24 sec No Message-Authenticator attribute found Incoming RADIUS packet did not have correct Message-Authenticator - dropped STA 00:00:00:00:00:02: No RADIUS RX handler found (type=0 code=2 id=0) - dropping packet This is from my radiusd.conf: When it is there, radius sends an Access-Accept. ldap ldap1 { server = "globalcatalogue" port = 3268 #global catalogue server identity = "testrad(a)TDE002.MYDOM.NET" password = "mypass" basedn = "dc=MYDOM,dc=NET" filter = "(&(servicePrincipalName=%{Stripped-User-Name:-%{User-Name}})(objectClass=computer)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))" ldap_debug= 0xFFFF timeout = 40 timelimit = 30 net_timeout = 10 tls { start_tls = no } dictionary_mapping = ${raddbdir}/ldap.attrmap groupmembership_attribute = "primaryGroupID" } authorize { preprocess eap ldap1 { notfound = reject } files } The complete output of radius -AX is lengthy and therefore nor included. It can be found at: http://www.wegener-net.de/fr/bad-group , where the error occurs, http://www.wegener-net.de/fr/ok-nogroup , where the authentication works as expected. As mentioned above, the only difference in the configuration is the use of groupmembership. Any hints are really appreciated. Thanks Norbert Wegener

PAM client password change
by John Kelly 17 Dec '05

17 Dec '05

I see that >http://www.freeradius.org/pam_radius_auth/README says > This is the PAM to RADIUS authentication module. It allows any >Linux or Solaris machine to become a RADIUS client for authentication >and password change requests. ^^^^^^^^^^^^^^^^^^^^^ OK! But then http://www.freeradius.org/pam_radius_auth/USAGE says > The module takes a number of configuration options. > Password changing is not implemented, as the RADIUS protocol does not ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ So README says yes, and USAGE says no. I want take all my users out of /etc/passwd and put them in a RADIUS server (running on the same host). And it would be nice if they could change their own passwords. But after reading the documents above, I don't know what to believe. Is this possible with pam_radius?

EAP-PEAP and windows supplicant behaviour
by Riccardo Veraldi 17 Dec '05

17 Dec '05

Hello, I Tried EAP-PEAP with success, and it works great with freeradius. My question (perhaps off topic) is how to change the default behaviour of the XP PEAP supplicant ? If you insert login/password it remembers those setting and it will not prompt you for them anymore... how to solve this problem ? is there a registry key to modify ? anyone has a hint about this ? thanks Rick
