No veo donde le digas a postfix con que DN conectarse al directorio LDAP, si 
le dices a que host, a que base dn, pero no como autenticarse con el servidor 
LDAP, mira la seccion de mi documento:

4.2.2. Configurando las fuentes LDAP

http://tuxjm.net/docs/mailserver-howto/ch04s04.html#section-4.4.2.2

Ahi yo describo como configurarlo, a mi me funciona, si tu tienes difernete tu 
directorio es cuestion de que adaptes el filtro.

Saludos.
