Authority Override

In many scenarios, such as https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/wiki/Multi-tenant-client_credential-use, it is useful to specify the AAD tenant at the request level instead of the app level. However, the app and the request must always the same cloud, i.e. the host of the authority URL must not be different.

var app =  ConfidentialClientApplicationBuilder
                .Create(PublicCloudConfidentialClientID)
                .WithAuthority("https://login.microsoft.com/common", true)
                .Build();

var result = await app.AcquireTokenForClient(scopes)
                      .WithAuthority("https://login.microsoft.com/123456-1234-2345-1234561234");
