Connect LDAP service to local domain

Is there anyone who can tell me if it's possible to connect form the LDAP service to a local domain?

I have made a new local domain with some groups and users in the Domain management in LC ES admin module.

Now I want to retrieve those users to my prcess in workbench with the LDAP service, but I can't get it to connect to the new domain (it works fine when I connect to our company AD).

I have tried with Base DN: DC=NewDomain,DC=local and Search filter: cn=* but with no luck :-(

Is it possible to connect to the local domaim from the LDAP service if it is, what should the "Base DN" look like and what are the atributes to use in the search filter?

Thanks
