Azure AD Groups, Administrative Roles, and user-defined roles

By Luke Latham and Javier Calvarro Nelson

Azure Active Directory (AAD) provides several authorization approaches that can be combined with ASP.NET Core Identity:

  • User-defined groups
    • Security
    • O365
    • Distribution
  • Roles
    • Built-in Administrative Roles
    • User-defined roles

The guidance in this article applies to the Blazor WebAssembly AAD deployment scenarios described in the following topics:

User-defined groups and built-in Administrative Roles

To configure the app in the Azure portal to provide a groups membership claim, see the following Azure articles. Assign users to user-defined AAD groups and built-in Administrative Roles.

The following examples assume that a user is assigned to the AAD built-in Billing Administrator role.

The single groups claim sent by AAD presents the user's groups and roles as Object IDs (GUIDs) in a JSON array. The app must convert the JSON array of groups and roles into individual group claims that the app can build policies against.

Extend RemoteUserAccount to include array properties for groups and roles.


using System.Text.Json.Serialization;
using Microsoft.AspNetCore.Components.WebAssembly.Authentication;

public class CustomUserAccount : RemoteUserAccount
    public string[] Groups { get; set; }

    public string[] Roles { get; set; }

Create a custom user factory in the standalone app or Client app of a Hosted solution. The following factory is also configured to handle roles claim arrays, which are covered in the User-defined roles section:

using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.WebAssembly.Authentication;
using Microsoft.AspNetCore.Components.WebAssembly.Authentication.Internal;

public class CustomUserFactory
    : AccountClaimsPrincipalFactory<CustomUserAccount>
    public CustomUserFactory(NavigationManager navigationManager,
        IAccessTokenProviderAccessor accessor)
        : base(accessor)

    public async override ValueTask<ClaimsPrincipal> CreateUserAsync(
        CustomUserAccount account,
        RemoteAuthenticationUserOptions options)
        var initialUser = await base.CreateUserAsync(account, options);

        if (initialUser.Identity.IsAuthenticated)
            var userIdentity = (ClaimsIdentity)initialUser.Identity;

            foreach (var role in account.Roles)
                userIdentity.AddClaim(new Claim("role", role));

            foreach (var group in account.Groups)
                userIdentity.AddClaim(new Claim("group", group));

        return initialUser;

There's no need to provide code to remove the original groups claim because it's automatically removed by the framework.

Register the factory in Program.Main (Program.cs) of the standalone app or Client app of a Hosted solution:

    CustomUserAccount>(options =>
.AddAccountClaimsPrincipalFactory<RemoteAuthenticationState, CustomUserAccount, 

Create a policy for each group or role in Program.Main. The following example creates a policy for the AAD built-in Billing Administrator role:

builder.Services.AddAuthorizationCore(options =>
    options.AddPolicy("BillingAdministrator", policy => 
        policy.RequireClaim("group", "69ff516a-b57d-4697-a429-9de4af7b5609"));

For the complete list of AAD role Object IDs, see the AAD Adminstrative Role Group IDs section.

In the following examples, the app uses the preceding policy to authorize the user.

The AuthorizeView component works with the policy:

<AuthorizeView Policy="BillingAdministrator">
            The user is in the 'Billing Administrator' AAD Administrative Role
            and can see this content.
            The user is NOT in the 'Billing Administrator' role and sees this

Access to an entire component can be based on the policy using [[Authorize]] attribute directive](xref:security/blazor/index#authorize-attribute) (AuthorizeAttribute):

@page "/"
@using Microsoft.AspNetCore.Authorization
@attribute [Authorize(Policy = "BillingAdministrator")]

If the user isn't logged in, they're redirected to the AAD sign-in page and then back to the component after they sign in.

A policy check can also be performed in code with procedural logic:

@page "/checkpolicy"
@using Microsoft.AspNetCore.Authorization
@inject IAuthorizationService AuthorizationService

<h1>Check Policy</h1>

<p>This component checks a policy in code.</p>

<button @onclick="CheckPolicy">Check 'BillingAdministrator' policy</button>

<p>Policy Message: @policyMessage</p>

@code {
    private string policyMessage = "Check hasn't been made yet.";

    private Task<AuthenticationState> authenticationStateTask { get; set; }

    private async void CheckPolicy()
        var user = (await authenticationStateTask).User;

        if ((await AuthorizationService.AuthorizeAsync(user, 
            policyMessage = "Yes! The 'BillingAdministrator' policy is met.";
            policyMessage = "No! 'BillingAdministrator' policy is NOT met.";

User-defined roles

An AAD-registered app can also be configured to use user-defined roles.

To configure the app in the Azure portal to provide a roles membership claim, see How to: Add app roles in your application and receive them in the token in the Azure documentation.

The following example assumes that an app is configured with two roles:

  • admin
  • developer


Although you can't assign roles to security groups without an Azure AD Premium account, you can assign users to roles and receive a roles claim for users with a standard Azure account. The guidance in this section doesn't require an Azure AD Premium account.

Multiple roles are assigned in the Azure portal by re-adding a user for each additional role assignment.

The single roles claim sent by AAD presents the user-defined roles as the appRoles's values in a JSON array. The app must convert the JSON array of roles into individual role claims.

The CustomUserFactory shown in the User-defined groups and AAD built-in Administrative Roles section is set up to act on a roles claim with a JSON array value. Add and register the CustomUserFactory in the standalone app or Client app of a Hosted solution as shown in the User-defined groups and AAD built-in Administrative Roles section. There's no need to provide code to remove the original roles claim because it's automatically removed by the framework.

In Program.Main of the standalone app or Client app of a Hosted solution, specify the claim named "role" as the role claim:

builder.Services.AddMsalAuthentication(options =>

    options.UserOptions.RoleClaim = "role";

Component authorization approaches are functional at this point. Any of the authorization mechanisms in components can use the admin role to authorize the user:

  • AuthorizeView component (Example: <AuthorizeView Roles="admin">)

  • [[Authorize]] attribute directive](xref:security/blazor/index#authorize-attribute) (AuthorizeAttribute) (Example: @attribute [Authorize(Roles = "admin")])

  • Procedural logic (Example: if (user.IsInRole("admin")) { ... })

    Multiple role tests are supported:

    if (user.IsInRole("admin") && user.IsInRole("developer"))

AAD Adminstrative Role Group IDs

The Object IDs presented in the following table are used to create policies for group claims. Policies permit an app to authorize users for various activities in an app. For more information, see the User-defined groups and AAD built-in Administrative Roles section.
