Identity 2.0 Invalid Login Attempt

Question

For some reason I am yet to discover, but after a successful registration and activation, I cannot login with the email address, instead I get an error "Invalid login attempt". As ASP.NET Identity 2.0 has improved with the use of Email login, I have modified the registration form to actually store a true username as the existing registration just seemed to duplicate by storing Username with the email address. Please see below the standard code that comes with `Install-Package Microsoft.AspNet.Identity.Samples -Pre'` following the creation of an empty ASP.NET Web Application (MVC) project: ``` var user = new ApplicationUser { UserName = model.Email, Email = model.Email }; ``` My function is now as follows: ``` var user = new ApplicationUser { TitleId = model.TitleId, SexId = model.SexId, Forename = model.Forename, Surname = model.Surname, UserName = model.UserName, Email = model.Email, JoinDate = System.DateTime.Now }; ``` As you can see UserName is now receiving a value from a form.

Accepted Answer

You have to modify `SignInHelper.PasswordSignIn` method. By default it uses `FindByNameAsync` to check if user with given name exists:

```
public async Task<SignInStatus> PasswordSignIn(string userName, string password, bool isPersistent, bool shouldLockout)
{
    var user = await UserManager.FindByNameAsync(userName);
    // (...)
```

change it to use `FindByEmailAsync`:

```
    var user = await UserManager.FindByEmailAsync(userName);
```

You can find `SignInHelper` class in *AppCode\IdentityConfig.cs` file.
