Insider Look
Windows Authorization Manager Model
Windows allows third parties to build in custom authorization modules into their software. This not only cuts down on the amount of programming a third party has to do to write an authentication and authorization system, but it also allows the enterprise to become more secure! When Windows Authorization Manager is used properly, it uses the built in controls already present in Windows.
Below you will find information from Microsoft on the Authorization Manager Model. It is important to remember that Microsoft documentation changes frequently and it’s important to view the information and understand changes right from the source who is maintaining it. In this case – Microsoft.
