The Authorities tab of the Group property sheet has the following components:
DBA Grants DBA authority to the group; a group with DBA authority can fully administer the database.
Resource Grants resource authority to the group; a group with resource authority can create database objects.
Remote DBA Grants Remote DBA authority to the group. The MobiLink client utility, dbmlsync, requires Remote DBA authority. A user ID with this type of authority should run the SQL Remote Message Agent to ensure that actions can be performed without creating security loopholes.
Backup Select this option to grant backup authority to the group.
Validate Select this option to grant validate authority to the group; a group with validate authority can perform the operations executed by the different VALIDATE statements, such as database, table, index, and checksum validation.
