Two-phase, "pass-thru" authentication possible?
by cwfnetman 16 Jun '11

I've got an interesting problem to try to solve and was curious if such a concept is even possible with FreeRadius. I've got to implement mac address filtering to a Cisco WiFi (WLC plus numerous LWAPPs) system that also requires Active Directory authentication of the Windows credentials of the user plus the wireless client workstation machine's AD account. Presently I'm using Microsoft IAS on a Windows 2003 server to act as my Windows AD radius server. Implementing the additional mac address filtering isn't my idea, so please refrain from questioning why. I know it really does nothing for true security, but I'm ordered to do so my authorities above me, so I must implement this mandate just because... well it's now become mandatory for my job. A problem is that the mac addresses of the wifi interfaces in all the various workstations are not always rigidly assigned to any particular laptop PC, the WiFi adapters in the set of client PCs are subject to frequent change and movement around the pool of PCs, so basically I need a simple whitelist (several hundred mac addresses) to validate against. If the incoming mac address on the authentication request is simply somewhere on the whitelist (anywhere within those hundreds of addresses), then I next need to authenticate the Windows AD credentials, and if they're good, and in a certain AD group, and their domain member workstation PC is in a certain machine account group, etc, etc, according to the set of remote access policies in the IAS server, then go ahead and "let 'em in". So, can FreeRadius be set up to perform a sort of two-phase, cascaded authentication such that the Cisco WiFi controller first sends the incoming authentication access-request to FreeRadius, which checks a big whitelist of pre-approved mac addresses, and if that tests good, then FreeRadius acts as a relay/proxy/radius client to pass the next ActiveDirectory authentication portion of the request off to my Windows IAS server, then if that part comes back good, to reassemble all the pieces-parts back together as a completed access-accept message and hand it back to the Cisco wireless system to let the wireless user in, and basically fool the Cisco WiFi system into thinking that one Radius server handled it all? -- View this message in context: http://freeradius.1045715.n5.nabble.com/Two-phase-pass-thru-authentication-… Sent from the FreeRadius - User mailing list archive at Nabble.com.

Attribute evaluation IF the attribute exists
by Tiberiu Breana 15 Jun '11

Greetings. Is it possible to authenticate users based on an attribute, if it exists (in their request), but ignore it if it doesn't? I've read the 'man users', but haven't found anything suitable. Any advice is welcome. Thanks!

Auth: rlm_krb5: [test1@CSP-BACK] krb5_rd_req() failed: Permission denied in replay cache code
by Jimmy 15 Jun '11

I have Kerberos 1.6 configured to use OpenLDAP 2.3.43 as a back end. I am trying to configure Freeradius 2.1.7 to authenticate to Kerberos. I am having problems getting Freeradiusto authenticate while started in daemon mode. When the process is started in debug mode it seems to funciton, but authentications while in daemon mode return the error: >Auth: rlm_krb5: [test1@CSP-BACK] krb5_rd_req() failed: Permission denied in replay cache code Since authentication works in debug mode I'm not sure what I can give to support the error besides the krb5kdc/slapd/radius log outputs and the client side output. Functional output of debug mode is included as well. I appreciate any help you can provide. If I should post any config files please let me know what you would like to see. Thank you very much. *****************client side output***************** radtest test1@CSP-BACK qwer krb 1812 SharedSecret Sending Access-Request of id 213 to [SERVER IP ADDRESS ] port 1812 User-Name = "test1@CSP-BACK" User-Password = "qwer" NAS-IP-Address = 127.0.0.1 NAS-Port = 1812 rad_recv: Access-Reject packet from host [SERVER IP ADDRESS ] port 1812, id=213, length=20 *********************************************** *****************radius log***************** Tue Jun 14 16:17:23 2011 : Auth: rlm_krb5: [test1@CSP-BACK] krb5_rd_req() failed: Permission denied in replay cache code *********************************************** *****************krb5kdc log***************** Jun 14 16:17:22 krb.csp krb5kdc[10954](info): AS_REQ (12 etypes {18 17 16 23 1 3 2 11 10 15 12 13}) [SERVER IP ADDRESS ]: ISSUE: authtime 1308082642, etypes {rep=18 tkt=18 ses=18}, test1@CSP-BACK for krbtgt/CSP-BACK@CSP-BACK Jun 14 16:17:23 krb.csp krb5kdc[10954](info): TGS_REQ (7 etypes {18 17 16 23 1 3 2}) [SERVER IP ADDRESS ]: ISSUE: authtime 1308082642, etypes {rep=18 tkt=18 ses=18}, test1@CSP-BACK for radius/krb.csp@CSP-BACK ******************************************** *****************slapd log***************** Jun 14 16:17:22 krb slapd[10742]: conn=9 op=54 SRCH base="cn=KRB,dc=CSPKRB" scope=2 deref=0 filter="(&(|(objectClass=krbPrincipalAux)(objectClass=krbPrincipal))(krbPrincipalName=test1@CSP-BACK))" Jun 14 16:17:22 krb slapd[10742]: conn=9 op=54 SRCH attr=krbprincipalname objectclass krbprincipalkey krbmaxrenewableage krbmaxticketlife krbticketflags krbprincipalexpiration krbticketpolicyreference krbUpEnabled krbpwdpolicyreference krbpasswordexpiration krbLastFailedAuth krbLoginFailedCount krbLastSuccessfulAuth nsaccountlock loginexpirationtime logindisabled modifytimestamp krbLastPwdChange krbExtraData krbObjectReferences Jun 14 16:17:22 krb slapd[10742]: conn=9 op=54 SEARCH RESULT tag=101 err=0 nentries=1 text= Jun 14 16:17:22 krb slapd[10742]: conn=9 op=55 SRCH base="cn=KRB,dc=CSPKRB" scope=2 deref=0 filter="(&(|(objectClass=krbPrincipalAux)(objectClass=krbPrincipal))(krbPrincipalName=krbtgt/CSP-BACK@CSP-BACK))" Jun 14 16:17:22 krb slapd[10742]: conn=9 op=55 SRCH attr=krbprincipalname objectclass krbprincipalkey krbmaxrenewableage krbmaxticketlife krbticketflags krbprincipalexpiration krbticketpolicyreference krbUpEnabled krbpwdpolicyreference krbpasswordexpiration krbLastFailedAuth krbLoginFailedCount krbLastSuccessfulAuth nsaccountlock loginexpirationtime logindisabled modifytimestamp krbLastPwdChange krbExtraData krbObjectReferences Jun 14 16:17:22 krb slapd[10742]: conn=9 op=55 SEARCH RESULT tag=101 err=0 nentries=1 text= Jun 14 16:17:23 krb slapd[10742]: conn=9 op=56 SRCH base="cn=KRB,dc=CSPKRB" scope=2 deref=0 filter="(&(|(objectClass=krbPrincipalAux)(objectClass=krbPrincipal))(krbPrincipalName=krbtgt/CSP-BACK@CSP-BACK))" Jun 14 16:17:23 krb slapd[10742]: conn=9 op=56 SRCH attr=krbprincipalname objectclass krbprincipalkey krbmaxrenewableage krbmaxticketlife krbticketflags krbprincipalexpiration krbticketpolicyreference krbUpEnabled krbpwdpolicyreference krbpasswordexpiration krbLastFailedAuth krbLoginFailedCount krbLastSuccessfulAuth nsaccountlock loginexpirationtime logindisabled modifytimestamp krbLastPwdChange krbExtraData krbObjectReferences Jun 14 16:17:23 krb slapd[10742]: conn=9 op=56 SEARCH RESULT tag=101 err=0 nentries=1 text= Jun 14 16:17:23 krb slapd[10742]: conn=9 op=57 SRCH base="cn=KRB,dc=CSPKRB" scope=2 deref=0 filter="(&(|(objectClass=krbPrincipalAux)(objectClass=krbPrincipal))(krbPrincipalName=radius/krb.csp@CSP-BACK))" Jun 14 16:17:23 krb slapd[10742]: conn=9 op=57 SRCH attr=krbprincipalname objectclass krbprincipalkey krbmaxrenewableage krbmaxticketlife krbticketflags krbprincipalexpiration krbticketpolicyreference krbUpEnabled krbpwdpolicyreference krbpasswordexpiration krbLastFailedAuth krbLoginFailedCount krbLastSuccessfulAuth nsaccountlock loginexpirationtime logindisabled modifytimestamp krbLastPwdChange krbExtraData krbObjectReferences Jun 14 16:17:23 krb slapd[10742]: conn=9 op=57 SEARCH RESULT tag=101 err=0 nentries=1 text= ******************************************** **************************************************************************************** **************************************************************************************** DEBUG MODE OUTPUT When I run the server in debug mode here is the output from radiusd -X: ******************************************** FreeRADIUS Version 2.1.7, for host x86_64-redhat-linux-gnu, built on Mar 31 2010 at 00:14:28 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

Slow Mysql Queries
by OzSpots - Carl Sawers 14 Jun '11

14 Jun '11

Hi All, I have a freeradius server which has some slow mysql queries and some errors like the below happen now and again(daily). We have actually just upgraded to this server and have imported all the MYsql data into the new server (it was working fine on the older quite similar server). One thing I have noticed; the server boots with around 280mb of ram used but after an hour or two is closer to 400mb used and stays around this point until rebooted again. My research says that the tables need to be indexed but it seems I would have to manually do this and I don't know which ones would need it anyway... and why would this be the case when it wasn't needed previously. The other thing that I have noticed is what appear to be doubled up entries in radius.log, (check the times) Anyone know what this could be?

Chap Password example?
by jenny 14 Jun '11

14 Jun '11

Hello, I have some enquiry on CHAP-Password for authentication. I'm trying to using CHAP-Password using freeradius client. Trying to look for some example but it seems there's no much example code i can use as a reference. Just wondering how can i do that? initially, i'm using PW_USER_PASSWORD and it works fine. here is my example code. if (rc_avpair_add(rh, &send, PW_USER_NAME, username, -1, 0) == NULL) { return ERROR_RC; } // fill in User-Password if (rc_avpair_add(rh, &send, PW_USER_PASSWORD, passwd, -1, 0) == NULL) { return ERROR_RC; } but i would like to change to CHAP-Password method, i understand i need to add the PW_CHAP_CHALLENGE as well. But I not sure how do i do that? if (rc_avpair_add(rh, &send, PW_USER_NAME, username, -1, 0) == NULL) { return ERROR_RC; } // fill in Set CHAP Password if (rc_avpair_add(rh, &send, PW_CHAP_PASSWORD, passwd, -1, 0) == NULL) { return ERROR_RC; } chap_state * cstate; rc_avpair_add(&send, PW_CHAP_CHALLENGE, cstate->challenge, cstate->chal_len); I'm having problem on the chap_state, it couldn't find the defination. I have installed pppd-2.4.5, but i couldn't find the library. Anyone can guide me through how do i do chap-password please? Also i have read the spec and some previous old thread, it said i need to do some calculation on specific crypto calculations. I not quite understand this, is there anyone can explain how do i do this? I guess there's some challenge string i need to pass in for PW_CHAP_CHALLENGE? what should assign to it? Any help/advice is very appreciate. Many thanks. regards, Jenny -- View this message in context: http://freeradius.1045715.n5.nabble.com/Chap-Password-example-tp4487335p448… Sent from the FreeRadius - User mailing list archive at Nabble.com.

Strange problem using hints to administer privileges
by den2k 13 Jun '11

13 Jun '11

Hello to the whole list, I'm experiencing a big and strange problem with the hints file. First I'll explain what I need to do. The users can access only to the machines of some companies OR to all the machine of the same kind, for example I could have user FOO who can have access only to the machines of customer custA and custB and is able to manage all the firewalls of all the customers. To do that I implemented a set of rules in hints which 1) Set the permissions for the logging user 2) Recognize the type of machine which the user is trying to access 3) Check the permissions relating the customers and sets the (custom) attribute itfgrant to "ok" if the user can log onto that machine 4) Check the permissions relating the type of machine and sets the (custom) attribute itfgrant to "ok" if the user can log onto that machine* * Then in the users file I check that attribute (itfgrant) along with the password to grant the access. The problem is that for each user the first login after the starting of the server is evaluated in the right way, with the right permissions. All the successive logins carry the same result as the first one! In other words if the first login resulted in a Access-Accept then EVERY successive login from that user will result in a Access-Accept. The same thing happens if the first login resulted in a Access-Reject. Restarting the server fixes the behaviour only for another login, then I have to restart the server again. Glossary: itfcliente contains the permissions for a given user itfgrant is used to grant access itfAll-* are used like booleans to give permissions to all the machines of a kind itfclient contains the name ho the customer which the machine belongs (like an huntgroup) Here is the hints file #START OF CONTENTS (it starts on the line numbered 37) # declaration of users permissions DEFAULT User-Name=="denABcfw" itfcliente+="clienteA", itfcliente+="clienteB", itfAll-cisco="yes", itfAll-fw="yes", itfAll-win="yes", Fall-Through:="yes" DEFAULT User-Name=="denf" itfAll-fw="yes", Fall-Through:="yes" DEFAULT User-Name=="denBC" itfcliente+="clienteB", itfcliente+="clienteC", Fall-Through:="yes" DEFAULT User-Name=="maxA" itfcliente+="clienteA", Fall-Through:="yes" ###### Detecting the customer DEFAULT Nas-Ip-Address =~ "10\.10\.8\.[0-2]?[0-9]*" itfclient:="clienteA", Fall-Through:="yes" DEFAULT Nas-Ip-Address =~ "10\.10\.9\.[0-2]?[0-9]*" itfclient:="clienteB", Fall-Through:="yes" DEFAULT Nas-Ip-Address =~ "10\.10\.10\.[0-2]?[0-9]*" itfclient:="clienteC", Fall-Through:="yes" ###### Detecting the kind of machine DEFAULT Nas-Ip-Address == 10.10.8.1 itftype="win", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.1 itftype="win", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.1 itftype="win", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.8.2 itftype="lin", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.2 itftype="lin", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.2 itftype="lin", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.8.3 itftype="cisco", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.3 itftype="cisco", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.3 itftype="cisco", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.8.4 itftype="fw", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.4 itftype="fw", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.4 itftype="fw", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.8.5 itftype="voip", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.9.5 itftype="voip", Fall-Through:="yes" DEFAULT Nas-Ip-Address == 10.10.10.5 itftype="voip", Fall-Through:="yes" # Match itfcliente with the customer customer (itfclient) DEFAULT itfcliente=="%{itfclient}" itfgrant:="ok", Fall-Through:="yes" # Match with the type of machine DEFAULT itftype=="cisco", itfAll-cisco=="yes" itfgrant:="ok", Fall-Through:="yes" DEFAULT itftype=="fw", itfAll-fw=="yes" itfgrant:="ok", Fall-Through:="yes" DEFAULT itftype=="win", itfAll-win=="yes" itfgrant:="ok", Fall-Through:="yes" DEFAULT itftype=="lin", itfAll-lin=="yes" itfgrant:="ok", Fall-Through:="yes" DEFAULT itftype=="voip", itfAll-cisco=="voip" itfgrant:="ok" #END OF CONTENTS And here come the users file # this one has access to customers A and B, and to all the cisco equipment, firewalls and windows machines denABcfw Cleartext-Password:="pippo", itfgrant=="ok" Fall-Through:="yes" # this one has access to all the firewall and nothing else denf Cleartext-Password:="pippo", itfgrant=="ok" Fall-Through:="yes" # this user has access only to the customers B and C denBC Cleartext-Password:="pippo", itfgrant=="ok" Fall-Through:="yes" # this one can access only to the customer A maxA Cleartext-Password:="pippo", itfgrant=="ok" Fall-Through:="yes" Here's the output of freeradius -X with some tests FreeRADIUS Version 2.1.10, for host i486-pc-linux-gnu, built on Nov 17 2010 at 04:06:04 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.

Authentication via SQL?
by Jason Antman 12 Jun '11

12 Jun '11

Hello, I was wondering if it is possible to have a sql authenticate{} section, and if so, how to define the queries? In the wiki, I find "Many people ask if they can "authenticate" users to their SQL database however the answer is "You are asking the wrong question." " So, my question is: "When doing PAP (actually EAP-TTLS/PAP, in my case), how do I check a user's cleartext User-Password against one stored in a MySQL database?" I'm currently doing this in my authenticate { } section, which uses a custom MySQL query along the lines of: SELECT ... FROM users WHERE username='%{User-Name}' AND pass = SHA2('%{User-Password}', 256) but since authentication is supposed to happen in the authenticate { } section, is there any way to move the password checking there? I don't see any indication of the authenticate{} group in sql.conf or sql/mysql/dialup.conf. Thanks, Jason Antman

Proxy based on User-Name with regex
by ivaylosp 11 Jun '11

Hi there, I have been trying to setup a freeradius server that will proxy the authentication to another server if the User-Name starts with 1234. So for instance a user logs in with username 1234XXXXXX then in section AUTHORIZE i have a policy that checks with regex if the username falls in this category: api_proxyRedirect{ if (User-Name =~ /[1-4]{4}[A-Za-z0-9]{6}/) { update control { Proxy-To-Realm := "myrealm" } } } Unfortunatelly everything works up to the point where the control needs to be updated. The server responds with ++++[control] not found. Any ideas will be very welcome.
