Denodo allows the option to include users and roles in a database export if the user is signed in as a server admin. This option is hidden however for local admins. I ran an export as a local admin and only the information from the database was exported, not the users and roles. The exporting of users and roles is a privilege that is not granted for local admins. For more clarification on local admins, you can look at the [Admin](https://community.denodo.com/docs/html/browse/latest/en/vdp/administration/databases_users_and_access_rights_in_virtual_dataport/user_and_access_right_in_virtual_dataport/user_and_access_right_in_virtual_dataport#admin-privilege) Privilege Section of VDP Admin Guide.
Hope this Helps!
