Re: Stale sessions problem
Kinda depends on what he is connected to. If you get a START record and a STOP record after the authentication from the device they are connected to you can check there. If you use sql for accounting, there will be a record created with a unique session id for the customer, and it will have a start time, but the stop time will be blank. This only is valid if the device they are connecting to supplies stop and start records when they logon and off or timeout.

Re: Please HELP!!! Any ideas??? MySQL and users file... Difference???
This is just a quess.. Since you are doing a sql look-up, I will bet it does the select * from xxx where username like btest. It returns both records, but only processes the first record, the passwords don't match and fails. I'll bet if you only have a single encrypted entry that will work. This is just a guess on my part but give it a shot. Gerry At 12:25 AM 2/25/2006, you wrote: Please anybody help me...

V1.10 File and LDAP Problems
Andrew thanks for the quick reply. Looks like you don't have the LDAP information setup correctly. FreeRADIUS can't login to LDAP with the settings (un)specified. > rlm_ldap: (re)connection attempt failed > rlm_ldap: search failed > rlm_ldap: ldap_release_conn: Release Id: 0 > modcall[authorize]: module "ldap" returns fail for request 0 > modcall: leaving group authorize (returns fail) for request 0 Yep, knew that, but expected to continue with the text auth since the user existed in that file. LDAP returns fail, which is weighted heavier than the both the "noop" returned by mschap and the "ok" returned by files. Because LDAP returns "fail," the entire request returns "fail." You can specify different weighted settings for noop, fail, etc, but the obvious answer is to fix your LDAP settings and then try again. How do you go about setting the weighting. I want to be able to use text, ldap and mysql so that we have various fall back options with a failure of the external databases (ldap and mysql). Once you can login to the LDAP, if the user does not exist in there then LDAP should return "noop" for the request. If you want a user to exist in both the LDAP and the users file with different passwords, that requires a bit of tweaking but I've got it working if you need to see Would like to see how you did it. Hope this helps! Andrew Gerry Dalton, Network System Support Consolidated Communications Cell: 214 532-1905 - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
V1.10 File and LDAP Problems
I have installed Freeradius 1.10, on Solaris 8. Using default radiusd.conf, and users file, added a couple of users. Tested and I am able to auth my testme user. I then add in the LDAP module, and un-comment ldap places in the radiusd.conf file. I again try to auth the same user who is in the user text file, and I can not auth that user. No other changes, just put the ldap directives in and it seems to break text file auth. I need to have the capability to fall back to text file of users in case the LDAP server is not available/problems/etc. Below are traces from each test. Note in the second test, that I know the login to the LDAP server is not valid, but this simulates the server being broken etc. I have also tested with a valid connection and get the same results.
