Bizhub c452 Active Directory

I have a question about implementing Active Directory in to the Bizhub c452. I am trying to get where instead of managing an address book at my company constatly, I can attach the scanner to our AD system and have all user profiles with email addresses added so that it is always up to date.

Is this possible and if so, how can it be done? I have tried configurign the LDAP server settings but it always say fail to connect if that is the route I need to go.

Thanks.
