Thanks for your help.
After reading all the documentation and config files, I
decided to simply add new users to the directory in a last ditch effort and try
again, and I got an Access-Accepted packet. Double checked.
Computers truly make me question my sanity
sometimes.
Regards,
Ricardo

Subject: Re: Troubleshooting FreeRadius +LDAP
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
