The Authorities tab of the User property sheet has the following components:
DBA Select this option to grant DBA authority to the user; a user with DBA authority can fully administer the database.
Resource Select this option to grant resource authority to the user; a user with resource authority can create database objects.
Remote DBA Select this option to grant Remote DBA authority to the user. The SQL Remote Message Agent should be run using a user ID with this type of authority to ensure that actions can be carried out without creating security loopholes. The MobiLink client utility, dbmlsync, also requires Remote DBA authority.
