Issues with Custom Claims in ASP.NET Core Identity for Role-Based Authentication
I'm currently implementing role-based authentication in an ASP.NET Core 6 application using Identity, but I'm running into issues with custom claims not being recognized after login... I've added a custom claim to a user upon registration, but when I try to retrieve it after logging in, it seems to be missing. Here's the code I used to add the claim during registration: ```csharp var user = new IdentityUser { UserName = model.Email, Email = model.Email }; var result = await _userManager.CreateAsync(user, model.Password); if (result.Succeeded) { await _userManager.AddClaimAsync(user, new Claim("CustomClaimType", "CustomClaimValue")); } ``` After this, I log in and retrieve the claims like this: ```csharp var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, isPersistent: false, lockoutOnFailure: false); if (result.Succeeded) { var user = await _userManager.FindByEmailAsync(model.Email); var claims = await _userManager.GetClaimsAsync(user); // Check for the custom claim } ``` However, when I check the claims collection after logging in, it doesn't include my custom claim. I've confirmed that the claim was added successfully during registration. I've also verified that the user is being loaded correctly in the login method, but it seems the claims do not persist through the authentication process. I've tried explicitly calling `await _userManager.UpdateClaimsAsync(user)` after adding the claim, but that doesn't seem to have any effect. Could there be something in the authentication middleware that strips custom claims, or do I need to handle something differently in the configuration? Additionally, I'm using the default cookie authentication setup. Here’s my Startup.cs configuration for authentication: ```csharp services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme) .AddCookie(options => { options.LoginPath = "/Account/Login"; options.LogoutPath = "/Account/Logout"; }); ``` Any insights or suggestions on what I might be missing here would be greatly appreciated! This is part of a larger CLI tool I'm building. Any examples would be super helpful. Any feedback is welcome!
