Hello, In order to correctly link to libssl.so.0.9.7 and libcrypto.so.0.9.7 at run time. I set LDFLAGS="-R/usr/local/openssl-0.9.7/lib" at compile time. When I execute the bin I get the following error: Thu Feb 16 18:39:40 2006 : Debug: read_config_files: reading dictionary Thu Feb 16 18:39:40 2006 : Error: Errors reading dictionary: dict_init: //usr/local/share/freeradius/dictionary.cablelabs[168]: dict_addvalue: value name too long Thu Feb 16 18:39:40 2006 : Error: Errors reading radiusd.conf If I remove line 168 in the cablelabs dictionary file everything loads fine: Thu Feb 16 18:43:14 2006 : Debug: security: reject_delay = 1 Thu Feb 16 18:43:14 2006 : Debug: security: status_server = no Thu Feb 16 18:43:14 2006 : Debug: main: debug_level = 0 Thu Feb 16 18:43:14 2006 : Debug: read_config_files: reading dictionary Thu Feb 16 18:43:14 2006 : Debug: read_config_files: reading naslist Thu Feb 16 18:43:14 2006 : Debug: read_config_files: reading clients This is the line I removed. dictionary.cablelabs[168] VALUE CableLabs-QoS-Release-Reason Inactivity-Resource-Recovery-Timer-Expiration 2 Alternativly, if I do not set LDFLAGS when I compile and set LD_LIBRARY_PATH at runtime (which I don't want to do) I do not get an error. Am I doing something wrong or is the dictionary file malformed? Please let me know if I can provide any other information. Thanks, Ryan

Re: Freeradius 1.1.0 and rlm_ldap

All worked fine untill i upgraded FreeRADIUS form 1.0.5 to 1.1.0. > From there on i cannot authenticate because the Auth-Type attribute is no more valorized to LDAP by the ldap module during authorize section. > ... > rlm_ldap: ldap_release_conn: Release Id: 0 > modcall[authorize]: module "ldap" returns ok for request 0 > modcall: leaving group authorize (returns ok) for request 0 > auth: No authenticate method (Auth-Type) configuration found for the request: Rejecting the user > ... > So if the Auth-Type LDAP is no more defined,how can i perform authentication against a LDAP server? I noticed the same symptoms after upgrading 1.0.5 to 1.1.0. Somehow the Auth-Type no longer had a value that would match the Auth-Type LDAP {...} entry in the authenticate section, even though the rlm_ldap successfully completed authorization. ChangeLog didn't mention incompatibilities, debug log with -X wasn't helpful, bug database turned out nothing, and mailing list archive turned up similar futhwo's problem report with no replies. Digging on rlm_ldap source and adding some debug printouts revealed that the Auth-Type wasn't left undefined like the debug message lead me to believe, but its value became the name of a LDAP instance (I'm using two LDAP servers in redundant radius group), which did not match the name of the Auth-Type LDAP {} authenticate section. In my case the solution was to replace the: authenticate { ... Auth-Type LDAP {...} with: authenticate { ... Auth-Type ldap-instance1 { ldap-instance1 } Auth-Type ldap-instance2 { ldap-instance2 } I would guess that futhwo's problem has a similar solution, perhaps replacing Auth-Type LDAP with Auth-Type ldap or giving a name to an instance and using that in the authenticate section. It would be helpful to document explicitly what comments in rlm_ldap.c indicate: * Module should default to LDAP authentication if no Auth-Type * specified. Note that we do this ONLY if configured, AND we * set the Auth-Type to our module name, which allows multiple * ldap instances to work. It wouldn't hurt if the inst->set_auth_type = 0 would be accompanied with a debug log entry, and if the pairadd in: if (inst->set_auth_type && (pairfind(*check_pairs, PW_AUTH_TYPE) == NULL) && request->password && (request->password->attribute == PW_USER_PASSWORD)) pairadd(check_pairs, pairmake("Auth-Type", inst->xlat_name, T_OP_EQ)); would also log the inst->xlat_name. But above all, please document incompatibilities between versions. Mark

Can I proxy by PPPoE service name?
by Zach T Hall 16 Feb '06

16 Feb '06

It seems that the features says it can be done, but I have no idea how. Basically I'm just wondering if I can take the service-name of the PPPoE server and have freeradius proxy out depending on which service name. Does anybody have any suggestions on where I might start looking for information on doing this type of thing? Thanks, Zach Hall

Allowing Access based on Group Membership
by Jay Lee 16 Feb '06

16 Feb '06

After a bit of effort I have managed to get Wireless with WPA encryption working with FreeRadius and an eDirectory LDAP Backend (using Universal password). My last task is to allow Wireless authentication only to members of a given LDAP Group. I seem to be having some issues though. Here is my ldap config in /etc/raddb/radiusd.conf: ldap { server = "ldap.pbu.edu" identity = "cn=admin,o=PBU" password = "password" basedn = "o=PBU" filter = "(uid=%{Stripped-User-Name:-%{User-Name}})" base_filter = "(objectclass=radiusprofile)" start_tls = yes tls_cacertfile = /etc/raddb/certs/rootder.b64 access_attr = "cn" dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 5 password_attribute = nspmPassword edir_account_policy_check=yes groupname_attribute = cn groupmembership_filter = "(|(&(objectClass=GroupOfNames)(member=%{Ldap-UserDn}))(&(objectClass=GroupOfUniqueNames)(uniquemember=%{Ldap-UserDn})))" groupmembership_attribute = radiusGroupName timeout = 4 timelimit = 3 net_timeout = 1 } If I empty out /etc/raddb/users completely, authentication works. If I put the following in users: DEFAULT LDAP-Group == "Wireless", Auth-Type := Accept Fall-Through = No DEFAULT Auth-Type := Reject and start freeradius with "radiusd -X -A" I get: rlm_ldap: Entering ldap_groupcmp() radius_xlat: 'o=PBU' radius_xlat: '(uid=jlee)' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in o=PBU, with filter (uid=jlee) rlm_ldap: ldap_release_conn: Release Id: 0 radius_xlat: '(|(&(objectClass=GroupOfNames)(member=cn=jlee,o=PBU))(&(objectCla ss=GroupOfUniqueNames)(uniquemember=cn=jlee,o=PBU)))' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in o=PBU, with filter (&(cn=Wireless)(|(&(objectClas s=GroupOfNames)(member=cn=jlee,o=PBU))(&(objectClass=GroupOfUniqueNames)(uniquem ember=cn=jlee,o=PBU)))) rlm_ldap::ldap_groupcmp: User found in group Wireless rlm_ldap: ldap_release_conn: Release Id: 0 users: Matched entry DEFAULT at line 1 modcall[authorize]: module "files" returns ok for request 1 rlm_ldap: - authorize rlm_ldap: performing user authorization for jlee radius_xlat: '(uid=jlee)' radius_xlat: 'o=PBU' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in o=PBU, with filter (uid=jlee) rlm_ldap: checking if remote access for jlee is allowed by cn rlm_ldap: Added the eDirectory password in check items rlm_ldap: looking for check items in directory... rlm_ldap: looking for reply items in directory... rlm_ldap: user jlee authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns ok for request 1 modcall: group authorize returns updated for request 1 rad_check_password: Found Auth-Type Accept rad_check_password: Auth-Type = Accept, accepting the user Processing the post-auth section of radiusd.conf modcall: entering group post-auth for request 1 rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: ldap_release_conn: Release Id: 0 modcall[post-auth]: module "ldap" returns ok for request 1 modcall: group post-auth returns ok for request 1 Sending Access-Accept of id 194 to 10.1.1.44:32769 Finished request 1 However, the wireless client never quite seems to finish associating. Any ideas what I'm doing wrong here? What should the users file look like to allow anyone who is a member of the Wireless LDAP group and deny everyone else?

Re: Re: how to disconnect user after quota given to him finishes ?
by Rupesh Amatya 16 Feb '06

16 Feb '06

Dear all, The user gets logged out exactly after the time set in Session Time Out. But I am trying to create package like 4hours per day, 2 hours perday. If I put 4hours in Session time and after using 3 hours , if he disconnects and then reconnects, he can again use 4 hours. Is there a way that he can no more log in after he uses 4 hours/day ? Thanking you all, Rupesh Amatya -------- Original Message -------- ==> From: Lewis Bergman <lbergman(a)wtxs.net> ==> Date: Wed, 15 Feb 2006 08:38:33 -0600 Dear all, I am using Freeradius(with mysql as database for users ) with Mikrotik as NAS. This for PPPOE users. I used Dialup Admin to manage freeradius. There is default package of 4hours/day but the users do not get > disconnect after 4 hours. It just shows " Out of Quota". What needs > to be done to automatically disconnect user after the daily quota is > finished ? ************************************** There a few session attrbutes you could use for this. Session-Timeout is the first one that springs to mind. I don't know if the client will pay attention to it though.

Possibility to set acct_table1 outside of sql.conf?
by Andreas Engler 16 Feb '06

16 Feb '06

Dear All, i would like to insert Accounting-Information in different tables for different NASs. Therefor i would use different sql-Instances and the acct_users file. The instances would only differ in acct_tabl1 and acct_table2. I tryed to set the variables in the sections of every instance in radiusd.conf before including sql.conf. In sql.conf i commented out the variables. But then there is reported an error, that the variable acct_table1 is unknown. Is there a possibility to set the variables acct_table1 and acct_table2 in the sections for the different instances in radiusd.conf? Or have i to provide for every instance an own sql.conf. Hopefully my problem gets clear!? Thank you Andreas Engler

Hi All, I'm keen to start using the rlm_perl module now that it has been made stable. However I find that the documentation relating to the module is sparse. Is there any official documentation on this module that anyone knows of? I would also like to know whether the perl module loaded is persistent. Thanks Philip

flat file user
by Priscilla B 15 Feb '06

15 Feb '06

Hi everyone, I have a question, have anyone of you using flat file for user database? If so, Can we use some script to update the content? If so do you guys have some examples? For example if i limited user A to use only 4 hours. and after he use 2 hours, and log out, I want to update the detail file, so user A data will become only 2 hours now. I know we can do that with sql and others . but how about flat file. Need a light here. thanks a lot Priscilla --------------------------------- What are the most popular cars? Find out at Yahoo!

pam_radius and Cisco ACS
by Tom 15 Feb '06

15 Feb '06

I have been tasked with having all non windows devices on our network to authenticate against our Active Directory, which is the reason we are using Cisco ACS. ACS currently authenticates for all cisco devices against our AD, via the external windows database option. I am now trying to get pam_radius to do the same with ACS's radius. I have compiled pam_radius and it appears to be working as intended, however Cisco ACS reports "External DB User Invalid or bad password" anytime I try to use the same credentials that properly authenticate with ACS's tacacs on a linux or freebsd server. The username shows up properly on the ACS server, so I am assuming that the NAS is sending the proper username, but it appears that the password is not being sent correctly. I know the ACS server is trying to authenticate against AD because after so many tries the account get's locked out. Has anyone been able to accomplish what I am trying to do here? Any suggestions besides "lose ACS" to get this to work? Is there something I can pass to the pam_radius module to have it transmit the password the way the ACS server is expecting to see it? I appreciate any help or suggestions anyone can provide in advance. Thank you, Tom
