How to enable/disable log 'Error: Ignoring request to authentication address...'
by Christian Springer 25 Nov '14

25 Nov '14

Hello, I'm receiving radius requests from a client not in the clients.conf, but the log message is not appearing. Is there a way to enable/disable that message ? It seems I've disabled the log output somehow... Thank you, regards Chris

rlm_cache updates for v3.0.x
by Arran Cudbard-Bell 25 Nov '14

25 Nov '14

The rlm_cache module will act as described in the notes in raddb/cache in v3.0.x. The main change between 3.0.5 rlm_cache and 3.0.6 rlm_cache are that it will return different rcodes for different cache states. In <= v3.0.5 ------------ The module returns "ok" if it found a cache entry. The module returns "updated" if it added a new cache entry. The module returns "noop" if it did nothing. In >= v3.0.6 ------------ The module returns "ok" if it found or created a cache entry. The module returns "updated" if it merged a cached entry. The module returns "noop" if it did nothing. The module returns "fail" on error. The full list of return code for the various runtime options are documented here: https://github.com/FreeRADIUS/freeradius-server/blob/v3.0.x/raddb/mods-avai… The second change is that the cache module will now default to *not* merging the cached attributes back into the current request when creating a cache entry. You can still force the server to do this by setting control:Cache-Merge := yes. The original reason for merging the Cache-Entry into the current request was so that the results of xlat expansions performed by the cache module would be available. Almost no one used the rlm_cache module to cache the results of xlat expansions however, and the behaviour had some odd side effects when working with attribute references, so it seems more sensible to leave it disabled by default. If anyone has any objections to the above behaviour changes, feel free to post them to the list. We also decided that the multivalued conditions were pretty useful and should be pulled into v3.0.x as well. The test coverage of the condition parser/evaluator is good, we don't expect any issues with it. Testing of current v3.0.x branch would be appreciated. -Arran Arran Cudbard-Bell <a.cudbardb(a)freeradius.org> FreeRADIUS development team FD31 3077 42EC 7FCD 32FE 5EE2 56CF 27F9 30A8 CAA2

Question about SQL fail open in post-auth and keyed-balance use in load balancing configuration
by John Douglass 24 Nov '14

24 Nov '14

Question 1: I thought I once read how to add this "fail open" in regards to using an SQL module. I have a table that gets updated after an auth, but if the DB is slow or there is a network issue, I want it to go on. It's not vital to auth the user, just using it as a "location update" of sorts. Is this the correct configuration for this behavior? post-auth { redundant { sql_location handled } } Question 2: I am experimenting with load balancing. I read the comments about keyed-balance: # keyed-balance - the home server is chosen by hashing (FNV) the contents of the Load-Balance-Key attribute from the control items. The request is then sent to home server # chosen by taking: # server = (hash % num_servers_in_pool). # # If there is no Load-Balance-Key in the control items, the load balancing method is identical to "load-balance". # # For most non-EAP authentication methods, The User-Name attribute provides a good key. An "unlang" policy can be used to copy the User-Name to the Load-Balance-Key # attribute. This method may not work for EAP sessions, as the User-Name outside of the TLS tunnel is often static, e.g. "anonymous@realm". If the username is a bad choice, I figured that the Calling-Station-Id (which in my case is the client MAC) would be a way to consistently have the same Load-Balance-Key. I am adding this to my server {} section: pre-proxy { update control { Load-Balance-Key := "%{Calling-Station-Id}" } updated } But I am only seeing use of one of the defined proxy servers as defined in my "home_server_pool {}" section when I force auth's to this server. Would not expect every MAC address to hash to the same radius back end given the variation of MAC addresses: home_server = vm1 home_server = vm2 Is the above pre-proxy{} segment doing what I think it should do? Update the Load-Balance-Key to the control before it hits the proxy segment? Just want some confirmation that I am on the right track or I am going about this wrong (or if what I'm trying is not a good idea/possible). Thanks! - John Douglass, Sr. Systems IT/Architect, Georgia Institute of Technology

RADIUS Server Authorization and Accounting - MY SQL Configuration - Please Help
by anusha mule 24 Nov '14

24 Nov '14

Hi, We have the following understanding RADIUS Authentication and Accounting flow :- 1. When the Access-request from the NAS, Server will search in the radcheck table to check the attributes for the user. 2. If check attributes are found and its matches to the user, then the server will pull the reply items (Attributes like Bandwidth, Volume, Timeout, etc) from the radreply table for this user and add it in the Access-Accept packet. 3. On receiving Access-Accept packet, session will get established for the user and Accounting-Start message will get transmitted to the Server. 4. The server will update the radacct table with Accounting start message. 5. When the station get disconnected, Session should get deleted and Accounting-Stop message should sent to the Server including user statistics (like Session-time, input-octets, output-octets, etc)in it. 6. Server will update the radacct table with all the attributed present in the STOP message. With let us consider the following simple scenario :- RADIUS Server having User details as User Name = Joe Password = Joe123 Timeout = 30000 Secs Step 1: During the initial connect - User should be authenticated and Access-Accept should contains the attribute value as 30000 Secs, mentioning the max duration that the user session is allowed. Once the session is established, RADIUS Accounting Start message is send to RADIUS server. Next let us say, User has been disconnected after 20000 Secs. Again, the RADIUS Accounting Stop message with the consumed duration of 20000 Secs shall be send to the RADIUS Server. Step 2: Now, when the same user tries to authenticate, he should be authenticated and the Access-Accept provide the Timeout attribute as 10000 Secs ( i.e. 30000 Secs – 20000 Secs) Here, let us assume the user used the full session duration and get time out. Again, the RADIUS Accounting Stop message with the consumed duration of 10000 Secs shall be send to the RADIUS Server. Step 3: Now, when the same user tries to authenticate, he should be rejected. How can the above be achieved using radius server configurations. Kindly help us in this. Thanks in advance. Thank you & Regards, Anusha M

Hi all! I have a problem with freeradius1.1 or NAS. " Deallocated entry for ip/port " messages were shown in some users. IP address that were shown as deallocated entry ip addresses were allocated as framed-ip-address for differenet user, but some were not allocated as framed-ip-address. I'm searching cause of this problem for few days. I'm sorry with my terrible English and silly query. if you need more information plese let me know.

UserDN escape problem and Group membership checking in 3.0.3
by Winders, Timothy A 21 Nov '14

21 Nov '14

I have FreeRadius 3.0.3 installed on Ubuntu 14.0.4 (free radius 3.0.3-ppa1~trustry package) I have everything setup with Active Directory for user authentication. This is working correctly, but I am having a problem with Active Directory group membership checking. It appears the problem is with the way FreeRadius escapes the UserDN when doing the query. I have tried various ldap configuration options, none of which quite work. If I remove all the filter settings from the group checking and only use the membership_attribute = "memberOf", I get the following Invalid DN syntax error: rlm_ldap (ldap): Bind successful (11) User object found at DN "CN=Winders\, Tim (0552),OU=Students,OU=SPC,DC=southplainscollege,DC=edu" (11) Checking user object membership (memberOf) attributes (11) Waiting for bind result... (11) Bind successful (11) Performing unfiltered search in 'CN=Winders, Tim (0552),OU=Students,OU=SPC,DC=southplainscollege,DC=edu', scope 'base' (11) Waiting for search result...

Notice the first User object found has the correct DN, with the comma in the CN= attribute escaped. This is the way the DN is stored in Active Directory. However, when doing the unfiltered search, the comma is no longer escaped resulting in the Invalid DN syntax. If I remove the membership_attribute and do the member checking in the group, I don¹t get the invalid DN (as the DN is no longer being searched), but the UserDn attribute is escaped differently rlm_ldap (ldap): Bind successful (11) User object found at DN "CN=Winders\, Tim (0552),OU=Students,OU=SPC,DC=southplainscollege,DC=edu" (11) Checking for user in group objects (11) EXPAND (&(objectClass=group)(member=%{control:Ldap-UserDn})) (11) --> (&(objectClass=group)(member=CN\3dWinders\2c Tim \280552\29\2cOU\3dStudents\2cOU\3dSPC\2cDC\3dsouthplainscollege\2cDC\3dedu) ) (11) Waiting for bind result...

Version 3.0.5 has been released
by Alan DeKok 21 Nov '14

21 Nov '14

We've added loads more regression tests, and a few nice features. Release notes are here: http://freeradius.org/version3.html * many more parts of the configuration are syntax checked when the server starts. * The detail file reader can now read a partial detail file, and then continue from where it left off * The couchbase module supports loading of dynamic clients * Better decoding of unknown VSAs * allow TLSv1.1 and TLSv1.2 in EAP. These can be selectively disabled. Other RADIUS implementations are doing the same. * escaping is now fixed. See "radiusd.conf", the "correct_escapes" setting. The last one is nice. It means you no longer need to use \\\\\\\\ in places. Just one escaping is good enough. Alan DeKok.
