MySQL Administrator :: 17.5.1 User Administration

These options affect the interface of the User Administration section of MySQL Administrator.

Show Global Privileges: If checked, the Global Privileges tab will be visible in the User Administration section. In that tab, you can grant users global privileges (as opposed to privileges on a database, table, or column level only). This may affect security. See The MySQL Access Privilege System for details. If unchecked, the Global Privileges tab will not be visible in the User Administration section.
Show Table/Column Privileges: In most situations, it is sufficient to grant either global or database privileges for users. You can hide the Table/Column Privileges tab in the User Administration section by enabling this checkbox.
