  The user's clear-text password wasn't obtained from the LDAP server.
This is to be expected in AD, as it doesn't supply them,

  This message should be clear: the user isn't found in /etc/passwd.

  The issue here isn't with basedn naming conventions.  It's that you
haven't set up FreeRADIUS to ask AD about authenticating the user.

  If the users log in with clear-text passwords, my suggestion is to
set up rlm_smb, and point it to the domain controller.  That will let
FreeRADIUs use AD for authentication.
