How to make IdentityServer to add user identity to the access token in C#?

To add user identity to the access token in IdentityServer using C#, you can follow these steps:

  • Create a custom ProfileService that implements the IProfileService interface. This service will be used to add claims to the access token.
public class CustomProfileService : IProfileService { private readonly UserManager<ApplicationUser> _userManager; public CustomProfileService(UserManager<ApplicationUser> userManager) { _userManager = userManager; } public async Task GetProfileDataAsync(ProfileDataRequestContext context) { var user = await _userManager.GetUserAsync(context.Subject); var claims = new List<Claim> { new Claim("sub", user.Id), new Claim("name", user.UserName) }; context.IssuedClaims.AddRange(claims); } public async Task IsActiveAsync(IsActiveContext context) { var user = await _userManager.GetUserAsync(context.Subject); context.IsActive = user != null; } }
  • In the ConfigureServices method of your Startup.cs file, register the CustomProfileService.
services.AddIdentity<ApplicationUser, IdentityRole>() .AddEntityFrameworkStores<ApplicationDbContext>() .AddDefaultTokenProviders(); services.AddIdentityServer() .AddDeveloperSigningCredential() .AddAspNetIdentity<ApplicationUser>() .AddProfileService<CustomProfileService>();
  • In your Client configuration, set the AlwaysIncludeUserClaimsInIdToken and AlwaysSendClientClaims properties to true.
new Client { ClientId = "myclient", ClientName = "My Client", AllowedGrantTypes = GrantTypes.ResourceOwnerPassword, ClientSecrets = { new Secret("secret".Sha256()) }, AllowedScopes = { "api1" }, AlwaysIncludeUserClaimsInIdToken = true, AlwaysSendClientClaims = true }
  • In your ApiResource configuration, set the UserClaims property to include the claims you want to include in the access token.
new ApiResource { Name = "api1", UserClaims = { "sub", "name" } }

With these steps, the access token will include the user identity claims specified in the CustomProfileService.
