Hello Dojo, are connection strings across the DMAs still required in a DMS cluster?

https://docs.dataminer.services/user-guide/Reference/MOPs/MOP_Implementing_connection_strings_in_a_DMS.html

Are there newer ways to configure the cluster so that connection strings can be avoided?

I understand the above procedure is required only when there are restrictions on the authentication within a DMS - would it be sufficient to have an "admin"-type account across all DMAs to avoid the need for connection strings?

Thanks
