How?
The workgroup information file in use when you log on must contain the user or group accounts that you want to assign permissions for at this time; however, you can assign permissions to groups and add users to those groups later.
Note Hidden objects aren't displayed in the Object Name box unless you select Hidden objects on the View tab of the Options dialog box (Tools menu).
Under Permissions, select the permissions you want to assign, or clear the permissions you want to remove for the group or user, and then click Apply. Repeat steps 4 and 5 to assign or remove permissions for additional objects for the current user or group.
Notes
How?
To import just the tables' definitions (not the data that they contain), click Options, and then under Import Tables, click Definition Only.
To import select queries as tables (for example, to create a read-only database), click Options, and then under Import Queries, click As Tables. Action queries import as queries no matter how this option is set.
To include relationships, custom menus and toolbars, or import/export specifications (Access database only), click Options, and then, under Import, select the items you want included. Microsoft Access won't import a toolbar, menu bar, or shortcut menu if it has the same name as one in the Access file that you're importing to.
The new database is now completely unsecured. The workgroup information file that was current when the new database was created in step 6 defines the Admins group for the new database.
