  That shouldn't need any magic eDirectory things.  Just treat it as a normal LDAP bind.

  The eDirectory magic is to allow eDirectory to send the clear-text password to FreeRADIUS, for things like MS-CHAP.

  So you're nod doing an anonymous search, and you're not doing bind as user.  Yes, it will fail.

  Configure anonymous search.  Configure bind as user.  Run the "ldap" module in the "authenticate" section.

  Delete all eDirectory magic from the configuration.
