Automatically add all active directory users and permissions

I’ve installed the latest 4.0 version of openfire and am using latest version of spark.

Users are automatically pulled in from active directory. When a user logs in, their contact list is empty. The user can manually add other users.

Is there a way to automatically add all other users and show them in the contact list and allow anyone to message anyone?

I’ve seen other solutions which suggest using groups and sharing, I’ve tried this but it says the group account system is not editable. i can’t create or edit any groups.
