Buenas !!

Mi problema es el siguiente: yo instale zimbra, y lo configure para que sirviera con samba para servidor de dominio !! me guié de la documentación oficial:

UNIX and Windows Accounts in Zimbra LDAP and Zimbra Admin UI 6.0 - Zimbra :: Wiki

y me a funcionado mas o menos bien !!!, pero al momento que un usuario intenta cambiar la contraseña desde windows, en el log de samba aparece lo siguiente:
