hi @syfy323,
I would recommend to contact sales@owncloud.com in case you need professional support with your ownCloud integration with your AD, ADFS or OpenLDAP.
Copying a LDIF wont be the best way to go, specially if you want to add in your Production AD.
I could also recommend to read this part of the documentation how to add your AD to your ownCloud:
https://doc.owncloud.com/server/10.4/admin_manual/configuration/user/user_auth_ldap.html
I hope it helps.
Carlos
