 This sample shows how a .NET Core 2.2 MVC Web app that uses [OpenID Connect](https://docs.microsoft.com/en-us/azure/active-directory/develop/v1-protocols-openid-connect-code) to sign in users and use Azure AD Application Roles (app roles) for authorization. App roles, along with Security groups are popular means to implement authorization.
 
-This application implements RBAC using Azure AD's Application Roles & Role Claims feature. Another approach is to use Azure AD Groups and Group Claims, as shown in [WebApp-GroupClaims](../../../5-WebApp-AuthZ/5-2-Groups). Azure AD Groups and Application Roles are by no means mutually exclusive; they can be used in tandem to provide even finer grained access control.
