Default Android contacts synchronization with active directory

Hi Android Fans,

I'm looking for a solution to synchronize to the local contact list from android with contact(user) information from Active Directory (name, phone number)

I've played for a while with the android app "LDAP sync" but I do not get filtered out the correct information.

It's me, did manage to get all the domain users in the contact list, but I want to filter users from a specific ou (organization unit).

Does anyone here have experience or perhaps another solution.

Thank you!
