I am new to IdentityServer and I have been struggling with this issue all day. So much so that I'm almost about to give up on this. I know this question has been asked over and over again and I have tried many different solutions but none seem to work. Hopefully you can help me push me in the right direction with this.

First I installed the IdentityServer4 templates by running `dotnet new -i identityserver4.templates` and created a new project with the is4aspid template by running `dotnet new is4aspid -o IdentityServer`.

After that i created a new IdentityServer database and ran the migrations. By that time I had a the default Identity database structure.

In Config.cs I changed `MVC client` to the following:

```
new Client
{
    ClientId = "mvc",
    ClientName = "MVC Client",

    AllowedGrantTypes = GrantTypes.Implicit,
    ClientSecrets = { new Secret("47C2A9E1-6A76-3A19-F3C0-S37763QB36D9".Sha256()) },

    RedirectUris = { "https://localhost:44307/signin-oidc" },
    FrontChannelLogoutUri = "https://localhost:44307/signout-oidc",
    PostLogoutRedirectUris = { "https://localhost:44307/signout-callback-oidc" },

    AllowOfflineAccess = true,
    AllowedScopes = { "openid", "profile", "api1", JwtClaimTypes.Role }                
},

```

And changed the `GetApis` method to this:

```
public static IEnumerable<ApiResource> GetApis()
{
    return new ApiResource[]
    {
        new ApiResource("api1", "My API #1", new List<string>() { "role" })
    };
}

```

There where of course no users in the database yet so i added a registration form and registered two dummy users, one with the username `admin@example.com` and one with the username `subscriber@example.com`.

To assign the roles to these user I created the following method in Startup.cs.

```
private async Task CreateUserRoles(IServiceProvider serviceProvider) {
    var RoleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
    var UserManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();

    IdentityResult adminRoleResult;
    IdentityResult subscriberRoleResult;

    bool adminRoleExists = await RoleManager.RoleExistsAsync("Admin");
    bool subscriberRoleExists = await RoleManager.RoleExistsAsync("Subscriber");

    if (!adminRoleExists) {
        adminRoleResult = await RoleManager.CreateAsync(new IdentityRole("Admin"));
    }

    if(!subscriberRoleExists) {
        subscriberRoleResult = await RoleManager.CreateAsync(new IdentityRole("Subscriber"));
    }

    ApplicationUser userToMakeAdmin = await UserManager.FindByNameAsync("admin@example.com");
    await UserManager.AddToRoleAsync(userToMakeAdmin, "Admin");

    ApplicationUser userToMakeSubscriber = await UserManager.FindByNameAsync("subscriber@example.com");
    await UserManager.AddToRoleAsync(userToMakeSubscriber, "Subscriber");
}

```

In the `Configure` method of the same class I add the the parameter `IServiceProvider services` and called the above method like so: `CreateUserRoles(services).Wait();`. By this time my database did have two roles in it.

Next I created a new solution (within the same project) and in the Startup.cs file of that solution I added the following in the `ConfigureServices` method.

```
    JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();

    services.AddAuthentication(options =>
    {
        options.DefaultScheme = "Cookies";
        options.DefaultChallengeScheme = "oidc";
    })
        .AddCookie("Cookies")
        .AddOpenIdConnect("oidc", options => {
            options.SaveTokens = true;
            options.ClientId = "mvc";
            options.ClientSecret = "32D7A7W0-0ALN-2Q44-A1H4-A37990NN83BP";
            options.RequireHttpsMetadata = false;
            options.Authority = "http://localhost:5000/";
            options.ClaimActions.MapJsonKey("role", "role");
        });

```

After that I added `app.UseAuthentication();` in the `Configure` method of the same class.

Then I created a new page with the following if statements.

```
if(User.Identity.IsAuthenticated) {
 <div>Yes, user is authenticated</div>
} 

if(User.IsInRole("ADMIN")) {
 <div>Yes, user is admin</div>
}

```

I logged in with `admin@example.com` but the second if statement returns `False`. I inspected all the claims by looping over them like so.

```
@foreach (var claim in User.Claims) {
    <dt>@claim.Type</dt>
    <dd>@claim.Value</dd>
}

```

But there was no role claim to be found, only sid, sub, idp, preferred\_username and name. 

I tried to get the role in there so that the second if statement returns True but after trying and trying I have not yet been able to make it work. Can someone see what I have to do in order to make this work? I am an absolute beginner in IdentityServer4 and trying my best to understand it. Any help will be appreciated. Thanks in advance!

**EDIT 1:**

Thanks to [this question](https://github.com/IdentityServer/IdentityServer4/issues/1786) and [this question](https://stackoverflow.com/questions/53976553/identityserver4-role-based-authorization-for-web-api-with-asp-net-core-identity/53977681#53977681) I got the feeling that I'm on the right track. I have made some modifications but I still can not get it to work. I just tried the following.

1. Created a new ProfileService class in my IdentityServer project with the following content.

```
public class MyProfileService : IProfileService {
 public MyProfileService() { }
 public Task GetProfileDataAsync(ProfileDataRequestContext context) {
  var roleClaims = context.Subject.FindAll(JwtClaimTypes.Role);
  List<string> list = context.RequestedClaimTypes.ToList();
  context.IssuedClaims.AddRange(roleClaims);
  return Task.CompletedTask;
 }

 public Task IsActiveAsync(IsActiveContext context) {
  return Task.CompletedTask;
 }
}

```

Next I registered this class in the ConfigureServices method by adding the line `services.AddTransient<IProfileService, MyProfileService>();`. After that I added a new a new line to the GetIdentityResources method, which looks like this now.

```
public static IEnumerable<IdentityResource> GetIdentityResources()
{
    return new IdentityResource[]
    {
        new IdentityResources.OpenId(),
        new IdentityResources.Profile(),
        new IdentityResource("roles", new[] { "role" })
};
}

```

I also added the roles to my Mvc client like so: `AllowedScopes = { "openid", "profile", "api1", "roles" }`.

Next I switched over to the other project and added the following lines in the .AddOpenIdConnect oidc. 

```
options.ClaimActions.MapJsonKey("role", "role", "role");
options.TokenValidationParameters.RoleClaimType = "role";

```

But still, I cannot get it to work like I want it to. Anyone knows what I am missing?
