EAP-Problem
by Florian Prester 22 Sep '06

22 Sep '06

Hi, firstly, we are using Freeradius for all kind of authentications - and It works very good!! -> Good Job to all of you. But, lately we have some EAP-Problems mostly with windows-clients. If a user authenticated correctly, after some time he gets disconnected and tries to reauthenticate, but it fails - see Log. Also I have some questions about eap at all. How should it work correctly. because I see up to 10 Authentication-Requests until the client is authenticated correctly. For example the client wants to do EAP-PEAP (Windows-client), but the radius says EAP-NAK: rlm_eap: Request found, released from the list rlm_eap: EAP NAK rlm_eap: EAP-NAK asked for EAP-Type/peap rlm_eap: processing type tls rlm_eap_tls: Initiate rlm_eap_tls: Start returned 1 modcall[authenticate]: module "eap" returns handled for request 231 modcall: leaving group authenticate (returns handled) for request 231 Sending Access-Challenge ... Finished request 231 What does it mean? Can I tune the process? Thank you all for your answers!

I am getting ready to switch my Radius servers over to FreeRadius and I would like to get some performance help. I know that FreeRadius can authenticate users from a MySQL database, from Linux users, and other options. For a performance and ease of maintenance which is recommended and why? Jory Privett WCCS

Problem configuration eap-tls
by listas 22 Sep '06

22 Sep '06

Hello!I'm OrgacK and this is my first post. I'm try to configure my own radius server for my house but before a lot of attempts I haven't got it. I always obtain same error: Starting - reading configuration files ... Using deprecated naslist file. Support for this will go away soon. Module: Loaded exec rlm_exec: Wait=yes but no output defined. Did you mean output=none? Module: Instantiated exec (exec) Module: Loaded expr Module: Instantiated expr (expr) Module: Loaded PAP Module: Instantiated pap (pap) Module: Loaded CHAP Module: Instantiated chap (chap) Module: Loaded MS-CHAP Module: Instantiated mschap (mschap) Module: Loaded System Module: Instantiated unix (unix) Module: Loaded eap rlm_eap: Loaded and initialized type md5 rlm_eap: Loaded and initialized type leap rlm_eap: Loaded and initialized type gtc rlm_eap_tls: Loading the certificate file as a chain rlm_eap: SSL error error:02001002:system library:fopen:No such file or directory rlm_eap_tls: Error reading Trusted root CA list rlm_eap: Failed to initialize type tls radiusd.conf[10]: eap: Module instantiation failed. radiusd.conf[1897] Unknown module "eap". radiusd.conf[1844] Failed to parse authenticate section. I think about the CA, server certificates and client certificates are created correctly. I don't know what i can do, have somebody any idea? PD: Sorry I'm Spanish and my English isn't very good.

Default radiusd.conf and Auth-Type LDAP comment
by Thibault Le Meur 22 Sep '06

22 Sep '06

Hi, This is just a comment on the default radiusd.conf provided information. In the authenticate section of the default radiusd.conf I can read about "Auth-Type LDAP": <quote> # Note that this means "check plain-text password against # the ldap database", which means that EAP won't work, # as it does not supply a plain-text password. </quote> While usually true, this assumption is a little confusing sometimes. Indeed, when EAP-TTLS uses PAP (not an EAP protocol I know) as its inside authentication protocol, a cleartext password is provided to Freeradius which is then able to use a simple ldap bind exchange to authenticate the user. Could we replace with something like that <quote> # Note that this means "check plain-text password against # the ldap database", which means that most EAP types won't work # as they do not supply a plain-text password (unless you use a # composite EAP scheme with and inner cleartext-enabled protocol # such as EAP-TTLS/PAP) </quote> But this is a little tricky... Or more simply: <quote> # Note that this means "check plain-text password against # the ldap database", which means that most EAP types won't work # as they do not supply a plain-text password # (an exception beeing EAP-TTLS with inner PAP authentication) </quote> The second one could be less confusing for people trying to setup EAP-TTLS/PAP on ldap directories but of course this is not a big deal...

Hi, > PAP!!!!! I have read that it is possibile make it with NT-passwd hash. > It is true? And how it is possible? you put the NT-Passwd hash into the LDAP as password field entry alan Ok, but how can I convert passwd from clear text to NT-Passwd format?

SMUX with FreeRadius
by Kshitij Korde 22 Sep '06

22 Sep '06

Hi I have integrated free radius server with NET-SNMP for monitoring radius server. Now the NET-SNMP daemon is detecting radius server. If I run radius server in debug mode I get following debug messages. Module: Instantiated radutmp (radutmp) main: smux_password = "verysecret" main: snmp_write_access = no inside oid_compare inside smux_connect SMUX connect try 1 inside smux_oid_dump SMUX open oid: 1.3.6.1.4.1.3317.1.3.1 SMUX open progname: radiusd SMUX open password: verysecret inside smux_oid_dump SMUX register oid: 1.3.6.1.2.1.67.1.1.1.1 SMUX register priority: -1 SMUX register operation: 1 inside smux_oid_dump SMUX register oid: 1.3.6.1.2.1.67.2.1.1.1 SMUX register priority: -1 SMUX register operation: 1 Listening on authentication *:1812 Listening on accounting *:1813 Ready to process requests. SMUX read start SMUX read len: 12 SMUX message received type: 67 rest len: 4 SMUX_RRSP SMUX_RRSP value: 0 errstat: 0 --- Walking the entire request list --- Nothing to do. Sleeping until we see a request. I may be asking some silly question since I don't have any idea how SMUX works. What are the functionalities provided by SMUX peer with respect to SNMP MODULE? Is there any mechanism where in we can send trap signal if radius server goes down? ============================================================================================================================ Tech Mahindra, formerly Mahindra-British Telecom.

MSCHAP and encripted passwd
by ivandal＠tiscali.it 22 Sep '06

22 Sep '06

Hi, I have a big problem with Radius and Ldap. There is a way to use MSCHAP v2 with the password stored in LDAP in some encripted manners? (md5, crypto...) In the client authentication software I cannot use pap/ttls, so Radius receive finally from the client unencripted passwd and have to compare with the passwd encrypted on Ldap. I cannote use PAP!!!!! I have read that it is possibile make it with NT-passwd hash. It is true? And how it is possible?
