How the Access Control List Works

You create an access control list by running the Access Control Wizard. The Access Control Wizard creates a page named Access Control Administration. This page contains a list of application modes and an Access Control List. Once you create the Access Control Administration page, you:

Run the Access Control Administration page.
Select one of the following application modes:
- Full access to all, access control list not used.
- Restricted access. Only users defined in the access control list are allowed.
- Public read only. Edit and administrative privileges controlled by access control list.
- Administrative access only.
Add users to the Access Control List.

In addition to creating the Access Control Administration page, the Access Control Wizard also creates:

two tables within the application's default schema to manage the access control
the authorization schemes that correspond to the application mode list options
the privileges available in the Access Control List

You can control access to a specific page or page component by selecting one of these authorization schemes on the page or component attributes pages. Once you create an Access Control, you can customize the page, tables and values to suit the specific needs of your application.
