Actually, I don't think this will help since the wireless controller IP that freeradius "sees" is *not* in the 192.168.100.* range. This controller uses LWAPP, so the IP ranges that the wireless networks use are totally contained within the wireless infrastructure, which means that the NAS IP is actually the LAN IP address of the controller. Again, it appears the only way for my to determine that the client request is coming from the wrong subnet is via the "cli" value. If Cisco would just fix the guest wireless implementation to only look at the internal database or give you an option to specify this, all would be well. But... since they don't, I have to figure out how to break RADIUS for one subnet and yet allow it to function for the rest. -----Original Message----- From: Sam Schultz [mailto:segfault90@hushmail.com] Sent: Thursday, March 15, 2007 12:46 PM To: freeradius-users(a)lists.freeradius.org; Capelle, Mark (PCMC-GB) Subject: Re: Reject authentication attempts based on "cli" value?

OK, I think I understand what you're asking. If you want to use LDAP for authorization ONLY, and something else for authentication, you could put an entry like this in your 'users' file: DEFAULT <check_items (ex: Realm == 'your_domain')> Autz-Type := <your_ldap_instance (ex: ldap)>, Auth-Type := <module_instance_for_authentication> Setting Autz-Type forces a certain type of authorization. Setting Auth-Type forces a certain type of authentication. Doing this in a DEFAULT entry causes ALL users that have Fall-Through set to yes to be passed through the specified authorization & authentication method. This could also be set on a per-user basis by changing DEFAULT to the a given user's username. >- >List info/subscribe/unsubscribe?

Actually, the example above was a typo. The 'User-Name =' line was 'User-Name :=' during testing, which is the part that is confusing, since the documentation states: Attribute := Value Always matches as a check item, and replaces in the configuration items any attribute of the same name. If no attribute of that name appears in the request, then this attribute is added. As a reply item, it has an identical meaning, but for the reply items, instead of the request items. According to this passage from the operators web page (http://wiki.freeradius.org/Operators) I would expect the original 'anonymous@test' entry to be replaced by 'test@test', and not be appended to the list like what is apparently happening. >... >> Followed by Accounting-Requests that still contain the anonymous > >> entry, >> so it is still using the oldest (first?)

The documentation helps ONLY if the documentation is consistent with the application's design, and ONLY if the NASes at the other end adhere to the RADIUS standard. Of course, I would chalk this up to a mistake in my configuration before asserting the former.

freeradius -peap ad/ldap
by joe vieira 15 Mar '07

Hi all, I'm using the RHEL build of freeradius 1.0.1. I'm trying to do something that might seem totally stupid, so let me know if i am (no need to flame). I'm new to freeradius so bear with me a bit. i have eap-peap authentication working against our ad domain. peachy keen. what i would like to be able to do is, in our openldap environment, store attributes for retrieval by radius, cisco stuff/ etc... i assume the way to do this would be to use the authorization sections, but if you add ldap to that then it automatically adds ldap authentication...which i don't want.. ideas?

An entry like: DEFAULT Realm == "test", Autz-Type := sql-test User-Name = "%{User-Name}" does add a new User-Name attribute with the proper value, but I need a way to delete the anonymous@ entry still, because I Access-Accepts like this: Sending Access-Accept of id 134 to 192.168.0.5 port 5190 User-Name := "anonymous@test" User-Name := "test@test" Followed by Accounting-Requests that still contain the anonymous entry, so it is still using the oldest (first?) User-Name attribute. Is there any way at all to REMOVE already set attributes so they aren't re-sent to the NAS? For that matter, shouldn't the "use_tunneled_reply = yes" in the ttls module configuration have kept me from having this problem? I also have copy_request_to_tunnel set to yes, but I doubt that should be causing a problem like this.
