  Yes... the User-DN is set from the query done during "authorize".

  The short answer is "don't have duplicate user names".

  The server is intended to work with unique user names.  It's possible
to configure it with duplicate user names, but it's more complicated.

  You'll need to update your configuration.  Maybe set the LDAP-User-DN
manually during authentication.
