Thank you. I will update here after trying it. I used unlang to do the disconnect on data exaustion, for now atleast.

User-Password to Cleartext-Password Conversion.
by Mustafa Mujahid/SYS 19 Jan '17

19 Jan '17

Hello, In which file exactly do I need to add this? Qoute > If it really is impossible to do this, the following unlang inserted above the call to the pap module may be used to copy User-Password to the correct attribute: if (!control:Cleartext-Password && control:User-Password) { update control { Cleartext-Password := "%{control:User-Password}" } } However, this should only be seen as a temporary, not permanent, fix. It is better to fix your databases to use the correct configuration. <Unqoute I changed the attribute temporarily in my DB and it worked, I would prefer using the same attribute as no specific detrimental effects about the above have been mentioned.

ERROR: No Auth-Type found: rejecting the user via Post-Auth-Type = Reject

Hello, I was working with free radius 3.0.12 and received the below errors in debug output. lm_sql (sql): Released connection (0) (0) [sql] = ok (0) [expiration] = noop (0) [logintime] = noop (0) pap: WARNING: No "known good" password found for the user.

The module requires a "known good" password, which it uses to validate the password given in the RADIUS packet. That "known good" password must be supplied by another module (e.g./rlm_files/,/rlm_ldap/, etc.), and is usually taken from a database. Unqoute > But I'm having a bit of trouble understanding. In my DB the Attribute is Cleartext-Password , which corresponds to a plain text password. So then why is this error generated. And how to mitigate it. What am I missing. The authorize section of my /etc/raddb/sites-enabled/default is read as: authorize { preprocess digest suffix sql expiration logintime pap } and authenticate as : authenticate { } Auth-Type PAP { pap } digest } Please let me know if any further information is required.

configuration for retrieving LDAP security group membership
by Adam Thompson 18 Jan '17

18 Jan '17

I need to configure FreeRADIUS Version 2.2.6 to retrieve LDAP security group membership, and am hoping someone here can help. In this case I have a web application that queries FreeRADIUS. FreeRADIUS then goes to the LDAP server and authenticates the user. User authentication works, but I've tried a couple of things to get the LDAP server to return security group membership with no luck. I have added and included a dictionary file with a definition of my vendor-defined attribute as follows: VENDOR Uplogix 10243 BEGIN-VENDOR Uplogix ATTRIBUTE Uplogix-User-Groups 3 string After reading through available documentation, I tried to return the groups with the following in the /erc/raddb/users file, but it doesn't work: DEFAULT Uplogix-User-Groups = Ldap-Group Should I instead be requesting the LDAP group in the post-auth section of the LDAP module? If so can I get an example of how the syntax should work for that? Thanks in advance, Adam Thompson

access reject problem
by Greg Antic 15 Jan '17

15 Jan '17

Hi List, I am seeing strange behaviour when using auth-type reject for a user. We are running version 3.0.12. # radiusd -X FreeRADIUS Version 3.0.12 The user account has been disabled and the auth-type set as per radcheck output below. The logs show rejected for many hours and all of a sudden it will start a session however the postauth table shows it was rejected. It's almost like freeradius gets tired of saying no and eventually gives in and says yes. Below the radpostauth shows the continual rejects which it has been rejected all day then all of a sudden at 00:02:46 the session starts. Does anyone have an explanation or idea as to why this would occur? Radcheck: username | Simultaneous-Use | := | 1 username | Cleartext-Password | := | password username | Auth-Type | := | Reject username | Calling-Station-Id | := | number radpostauth: username | Access-Reject | 2017-01-13 00:02:16 username | Access-Reject | 2017-01-13 00:02:00 username | Access-Reject | 2017-01-13 00:01:34 username | Access-Reject | 2017-01-13 00:01:09 username | Access-Reject | 2017-01-13 00:00:43 username | Access-Reject | 2017-01-13 00:00:18 radacct: username | acctstarttime username | 2017-01-13 00:02:46 Thanks, Greg
