This is working for me. As commented in other issue we should create a fork for this project and maintainign it.

related to this ..

it might be worth to see what features this Bundle provides beyond the new 2.8 LDAP component and refactor things into a new 2.8+ requiring version of this Bundle: http://symfony.com/blog/new-in-symfony-2-8-ldap-component

So, are we going to fix this issue or we can wait another 5 months?
