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.

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 ...
