ASP.NET Identity Provider SignInManager Keeps Returning Failure

Question

I have an issue with the standard ASP Identity provider for MVC5. As soon as I log in the method:

await SignInManager.PasswordSignInAsync(model.Email, model.Pass         


        

Answer 1

Bit old now, but here's my tuppence on this issue.

I was doing some static data creation in a utility to ensure some standard things were present in the Identity database (roles and an administrator account).

I was creating the entities and talking directly to the context to create any missing roles or that user. The issue I had was that I wasn't setting the NormalizedUserName and NormalizedEmail fields. I was simply setting Email and UserName.

The final code I use (with EF Core 2.x) is something like:

        if (!_context.Users.Any(_ => _.Id.Equals(Users.AdministratorId)))
        {
            var user = new ApplicationUser
            {
                Id = Users.AdministratorId,
                UserName = Users.AdministratorEmail,
                Email = Users.AdministratorEmail,
                EmailConfirmed = true,
                NormalizedEmail = Users.AdministratorEmail.ToUpper(),
                NormalizedUserName = Users.AdministratorEmail.ToUpper(),
                SecurityStamp = Guid.NewGuid().ToString()
            };

            var hasher = new PasswordHasher();
            user.PasswordHash = hasher.HashPassword(user, "our_password");

            _context.Users.Add(user);
        }
