Grouping Tasks into Roles in C++

In Authorization Manager, a role represents a category of users and the tasks those users are authorized to perform. Tasks are grouped together and assigned to a role definition, which is represented by an IAzTask object with its IsRoleDefinition property set to TRUE. The role definition can then be assigned to an IAzRole object, and users or groups of users are then assigned to that object. For more information about tasks and roles, see Roles.

The following example shows how to assign tasks to a role definition, create a role object, and assign the role definition to the role object. The example assumes that there is an existing XML policy store named MyStore.xml in the root directory of drive C, that this store contains an application named Expense, and that this application contains tasks named Submit Expense and Approve Expense.
