Windows authentication and custom authorization

The Microsoft identity platform uses the OAuth 2. Creating apps that each maintain their own username and password information incurs a high administrative burden when adding or removing users across multiple apps. Instead, your apps can delegate that responsibility to a centralized identity provider.

Delegating authentication and authorization to it enables scenarios such as:. The Microsoft identity platform simplifies authorization and authentication for application developers by providing identity as a service. It supports industry-standard protocols and open-source libraries for different platforms to help you start coding quickly. It allows developers to build applications that sign in all Microsoft identities, get tokens to call Microsoft Graph , access Microsoft APIs, or access other APIs that developers have built.

Next, we have to configure the application to use our new custom role provider by adding a RoleManager element to the system. Now your application will use the newly created role provider and you can begin to restrict access by your application-specific roles, like we saw in the first example.

Note that this is completely optional and is not needed for a custom role provider. The current authorize attribute is easy to use and works great. But it relies heavily on magic strings. If we passed an enum as the role and if that enum ever changed, the application will no longer compile until the enum is updated throughout the application. In the example below, we make our own authorize attribute that requires an enum. First, create a class that inherits from System.

In this case it's a small but common mistake of switching lines, the order is UseAuthentication who is the user and then UseAuthorization what is the user allowed to do. That explains why authorization doesn't work. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow.
