The LDAP Thing again...
by Kent Thomas 09 Sep '07

09 Sep '07

Hello, I'm new to FreeRadius, and have struggled for a couple of days now on how to get LDAP authentication to work. It would appear that the LDAP is actually authenticating, but then something goes wrong following that. I'm sure it is just something set wrong in the users file, but I do need some help. Forgive me if this has already been covered. Thanks a million, Kent Here is the debug info: -------------------------Debug Output-------------------------------------- Sat Sep 8 23:32:21 2007 : Info: Ready to process requests. rad_recv: Access-Request packet from host 192.168.178.121:57635, id=123, length=44 User-Name = "kent" User-Password = "00000" Sat Sep 8 23:33:22 2007 : Debug: Processing the authorize section of radiusd.conf Sat Sep 8 23:33:22 2007 : Debug: modcall: entering group authorize for request 0 Sat Sep 8 23:33:22 2007 : Debug: modsingle[authorize]: calling preprocess (rlm_preprocess) for request 0 Sat Sep 8 23:33:22 2007 : Debug: modsingle[authorize]: returned from preprocess (rlm_preprocess) for request 0 Sat Sep 8 23:33:22 2007 : Debug: modcall[authorize]: module "preprocess" returns ok for request 0 Sat Sep 8 23:33:22 2007 : Debug: modsingle[authorize]: calling suffix (rlm_realm) for request 0 Sat Sep 8 23:33:22 2007 : Debug: rlm_realm: No '@' in User-Name = "kent", looking up realm NULL Sat Sep 8 23:33:22 2007 : Debug: rlm_realm: No such realm "NULL" Sat Sep 8 23:33:22 2007 : Debug: modsingle[authorize]: returned from suffix (rlm_realm) for request 0 Sat Sep 8 23:33:22 2007 : Debug: modcall[authorize]: module "suffix" returns noop for request 0 Sat Sep 8 23:33:22 2007 : Debug: modsingle[authorize]: calling eap (rlm_eap) for request 0 Sat Sep 8 23:33:22 2007 : Debg: rlm_eap: No EAP-Message, not doing EAP Sat Sep 8 23:33:22 2007 : Debug: modsingle[authorize]: reurned from eap (rlm_eap) for request 0 Sat Sep 8 23:33:22 2007 : Debug: modcall[authorize]: module "eap" returns noop for request 0 Sat Sep 8 23:33:22 2007 : Debug: modsingle[authorize]: calling files (rlm_files) for request 0 Sat Sep 8 23:33:22 2007 : Debug: users: Matched entry DEFAULT at line 154 Sat Sep 8 23:33:22 2007 : Debug: modsingle[authorize]: returned from files (rlm_files) for request 0 Sat Sep 8 23:33:22 2007 : Debug: modcall[authorize]: module "files" returns ok for request 0 Sat Sep 8 23:33:22 2007 : Debug: modsingle[authorize]: calling ldap (rlm_ldap) for request 0 Sat Sep 8 23:33:22 2007 : Debug: rlm_ldap: - authorize Sat Sep 8 23:33:22 2007 : Debug: rlm_ldap: performing user authorization for kent Sat Sep 8 23:33:22 2007 : Debug: radius_xlat: '(uid=kent)' Sat Sep 8 23:33:22 2007 : Debug: radius_xlat: 'dc=pumpsystems,dc=com' Sat Sep 8 23:33:22 2007 : Debug: rlm_ldap: ldap_get_conn: Checking Id: 0 Sat Sep 8 23:33:22 2007 : Debug: rlm_ldap: ldap_get_conn: Got Id: 0 Sat Sep 8 23:33:22 2007 : Debug: rlm_ldap: attempting LDAP reconnection Sat Sep 8 23:33:22 2007 : Debug: rlm_ldap: (re)connect to 192.168.178.120:389, authentication 0 Sat Sep 8 23:33:22 2007 : Debug: rlm_ldap: bind as / to 192.168.178.120:389 Sat Sep 8 23:33:22 2007 : Debug: rlm_ldap: waiting for bind result ...

The reply packet may be # lost in the network, and the NAS will not see it.

(See 'max_requests'.) # # Useful range of values: 2 to 10 # cleanup_delay = 5 # max_requests: The maximum number of requests which the server keeps # track of. This should be 256 multiplied by the number of clients. # e.g. With 4 clients, this number should be 1024. # # If this number is too low, then when the server becomes busy, # it will not respond to any new requests, until the 'cleanup_delay' # time has passed, and it has removed the old requests. # # If this number is set too high, then the server will use a bit more # memory for no real benefit. # # If you aren't sure what it should be set to, it's better to set it # too high than too low. Setting it to 1000 per client is probably # the highest it should be. # # Useful range of values: 256 to infinity # max_requests = 1024 # bind_address: Make the server listen on a particular IP address, and # send replies out from that address. This directive is most useful # for machines with multiple IP addresses on one interface. # # It can either contain "*", or an IP address, or a fully qualified # Internet domain name. The default is "*" # # As of 1.0, you can also use the "listen" directive. See below for # more information. # bind_address = * # port: Allows you to bind FreeRADIUS to a specific port. # # The default port that most NAS boxes use is 1645, which is historical. # RFC 2138 defines 1812 to be the new port. Many new servers and # NAS boxes use 1812, which can create interoperability problems. # # The port is defined here to be 0 so that the server will pick up # the machine's local configuration for the radius port, as defined # in /etc/services. # # If you want to use the default RADIUS port as defined on your server, # (usually through 'grep radius /etc/services') set this to 0 (zero). # # A port given on the command-line via '-p' over-rides this one. # # As of 1.0, you can also use the "listen" directive. See below for # more information. # port = 0 # # By default, the server uses "bind_address" to listen to all IP's # on a machine, or just one IP. The "port" configuration is used # to select the authentication port used when listening on those # addresses. # # If you want the server to listen on additional addresses, you can # use the "listen" section. A sample section (commented out) is included # below. This "listen" section duplicates the functionality of the # "bind_address" and "port" configuration entries, but it only listens # for authentication packets. # # If you comment out the "bind_address" and "port" configuration entries, # then it becomes possible to make the server accept only accounting, # or authentication packets. Previously, it always listened for both # types of packets, and it was impossible to make it listen for only # one type of packet. # #listen { # IP address on which to listen. # Allowed values are: # dotted quad (1.2.3.4) # hostname (radius.example.com) # wildcard (*) # ipaddr = * # Port on which to listen. # Allowed values are: # integer port number (1812) # 0 means "use /etc/services for the proper port" # port = 0 # Type of packets to listen for. # Allowed values are: # auth listen for authentication packets # acct listen for accounting packets # # type = auth #} # hostname_lookups: Log the names of clients or just their IP addresses # e.g., www.freeradius.org (on) or 206.47.27.232 (off). # # The default is 'off' because it would be overall better for the net # if people had to knowingly turn this feature on, since enabling it # means that each client request will result in AT LEAST one lookup # request to the nameserver. Enabling hostname_lookups will also # mean that your server may stop randomly for 30 seconds from time # to time, if the DNS requests take too long. # # Turning hostname lookups off also means that the server won't block # for 30 seconds, if it sees an IP address which has no name associated # with it. # # allowed values: {no, yes} # hostname_lookups = no # Core dumps are a bad thing.

If you # don't have any spare threads, then the request handling will # be delayed while a new thread is created, and added to the pool. # # You probably don't want too many spare threads around, # otherwise they'll be sitting there taking up resources, and # not doing anything productive. # # The numbers given below should be adequate for most situations. # thread pool { # Number of servers to start initially --- should be a reasonable # ballpark figure. start_servers = 5 # Limit on the total number of servers running. # # If this limit is ever reached, clients will be LOCKED OUT, so it # should NOT BE SET TOO LOW. It is intended mainly as a brake to # keep a runaway server from taking the system with it as it spirals # down... # # You may find that the server is regularly reaching the # 'max_servers' number of threads, and that increasing # 'max_servers' doesn't seem to make much difference. # # If this is the case, then the problem is MOST LIKELY that # your back-end databases are taking too long to respond, and # are preventing the server from responding in a timely manner. # # The solution is NOT do keep increasing the 'max_servers' # value, but instead to fix the underlying cause of the # problem: slow database, or 'hostname_lookups=yes'. # # For more information, see 'max_request_time', above. # max_servers = 32 # Server-pool size regulation. Rather than making you guess # how many servers you need, FreeRADIUS dynamically adapts to # the load it sees, that is, it tries to maintain enough # servers to handle the current load, plus a few spare # servers to handle transient load spikes. # # It does this by periodically checking how many servers are # waiting for a request. If there are fewer than # min_spare_servers, it creates a new spare. If there are # more than max_spare_servers, some of the spares die off. # The default values are probably OK for most sites. # min_spare_servers = 3 max_spare_servers = 10 # There may be memory leaks or resource allocation problems with # the server. If so, set this value to 300 or so, so that the # resources will be cleaned up periodically. # # This should only be necessary if there are serious bugs in the # server which have not yet been fixed. # # '0' is a special value meaning 'infinity', or 'the servers never # exit' max_requests_per_server = 0 } # MODULE CONFIGURATION # # The names and configuration of each module is located in this section. # # After the modules are defined here, they may be referred to by name, # in other sections of this configuration file. # modules { # # Each module has a configuration as follows: # # name [ instance ] { # config_item = value # ... # } # # The 'name' is used to load the 'rlm_name' library # which implements the functionality of the module. # # The 'instance' is optional.

radcheck problem
by YvesDM 08 Sep '07

08 Sep '07

Hi, I want a specific user (call him john) NOT to be able to login through a specific nas. So I thought, just add this to radcheck INSERT INTO `radcheck` (`UserName`, `Attribute`, `op`, `Value`) VALUES ('john','NASIdentifier','!=','nas-id') (nas-id is the nasidentifier of the specific nas) Anyway, when I add this entry to radcheck, john gets rejected all the time, no matter what nas he's connecting to. Am I overlooking something? Kind regards

Hi Michael, > if you write a patch, why don't you implement all of the ocf features? Writing an OCF resource is not related to freeradius, but to Linux-ha project. So I think perhaps I'll be writing that OCF resource, but no further discussion will go on on this list since (imho) it's a bit off topic. :-) > Michael. Francesco.

reject_delay setting effecting Access-Accept responses

Has anyone seen the reject_delay setting in radiusd.conf effect the response time to subsequent access-accept responses? I haven't seen anything on this in the mailing list, but I wanted to check before I look into the code.

CA.all problem
by Mack Ragan 06 Sep '07

06 Sep '07

Hi, Using the provided script "CA.all", trying to create self-signed certs on a new freeradius box and running into a missing serial file problem. Executing the commands in the script line-by-line shows that the command "openssl ca -policy policy_anything -out newcert.pem -passin pass:whatever -key whatever -extensions xpserver_ext -extfile xpextensions -infiles newreq.pem" is what is looking for the file "./demoCA/serial" which does not exist. I think it is normally created during "CA.pl -newca" but this doesn't appear to happen with the script's command of "echo "newreq.pem" | /usr/local/ssl/misc/CA.pl -newca". I'm using OpenSSL version 0.9.8e. Anyone have this experience? Thanks!

Hi all, I'd like to integrate FR 1.1.7 installation with Heartbeat-2 but it seems that the initscript /etc/init.d/freeradius is not LSB compliant, so integration is not straightforward. Is there anybody working on this (very small) issue? Greetings, Francesco.
