I am not a Pro neither, but I have had my share of sleepless nights trying to figure out the same issues here. The problem does not seem to be freeradius here but the LDAP server The LDAP module cannot find the user "user1" in the LDAP database even though it successfully connected to it. Try to locate "user1" in the directory using ldapsearch or another tool , then use that information in you basedn info (in ldap.conf). Users are generally stored in the cn=users,dc=domain,dc=tld container I have found that with AD the ldap module cannot seem to find anything when searching the root of the domain ...

Greetings list users, I'm trying setup FreeRadius to work with LDAP in a deployment of ClearOS and have followed this How-To http://www.clearfoundation.com/docs/howtos/setting_up_freeradius2_to_use_lda... and this How-To http://deployingradius.com/documents/configuration/pap.html with success, up to the part of the inital radtest with credentials inserted in the users file. But when trying to use credentials from the LDAP directory, the Radius server returns an Access-Reject packet. Below is the output from the debug mode. *************************************************** login as: root root@192.168.3.5's <mailto:root@192.168.3.5%27s> password: Last login: Mon Sep 12 13:31:45 2011 from 192.168.3.2 [root@system ~]# service radiusd stop Stopping RADIUS server: [ OK ] [root@system ~]# radiusd -X FreeRADIUS Version 2.1.7, for host i686-redhat-linux-gnu, built on May 19 2010 at 13:10:59 Copyright (C) 1999-2009 The FreeRADIUS server project and contributors.
