Using Authorization in C++

You can use the Authorization Manager API to control access to application resources.

If you have an existing access control solution based on access control lists (ACLs) and want to avoid converting this solution to use Authorization Manager, you can continue to use ACLs to control access to resources. For information about controlling access to resources using ACLs, see Defining Permissions with ACLs in C++, Establishing a Client Context from a SID in C++, and Verifying Client Access with ACLs in C++.

Note

For large enterprises, there is a trade-off between administrative overhead and performance. As the number of secured resources and users increases, the administration of ACLs becomes more complicated. Performance is not affected because all required information about access rights is distributed to the secured resources. The performance of Authorization Manager is affected by scaling.
