Configure Microsoft.AspNet.Identity to allow email address as username

Question

I\'m in the process of creating a new application and started out using EF6-rc1, Microsoft.AspNet.Identity.Core 1.0.0-rc1, Microsoft.AspNet.Identity.EntityFramework 1.0.0-rc

Answer 1

If you are using ASP.Net webforms and are trying to accomplish this, simply open up your IdentityModels.vb/cs file and under Public Class UserManager, have it look as so:

Public Class UserManager
Inherits UserManager(Of ApplicationUser)

Public Sub New()
    MyBase.New(New UserStore(Of ApplicationUser)(New ApplicationDbContext()))
    Users = store
    UserValidator = New UserValidator(Of ApplicationUser)(Me) With {.AllowOnlyAlphanumericUserNames = False}
End Sub

Public Property Users() As IUserStore(Of ApplicationUser)
    Get
        Return m_Users
    End Get
    Private Set(value As IUserStore(Of ApplicationUser))
        m_Users = value
    End Set
End Property
Private m_Users As IUserStore(Of ApplicationUser)

End Class

Answer 2

You can allow this by plugging in your own UserValidator on the UserManager, or just by turning it off on the default implementation:

UserManager.UserValidator = new UserValidator<TUser>(UserManager) { AllowOnlyAlphanumericUserNames = false }

Answer 3

In my case i had a repository class working with authentication, that didn't let me use a "-" inside usernames.. The fix was inside the constructor here:

//-------------------------------------------------------
public AuthRepository()
//-------------------------------------------------------
{
    _ctx = new AuthContext();
    _userManager = new UserManager<IdentityUser>(new UserStore<IdentityUser>(_ctx));
    _userManager.UserValidator = new UserValidator<IdentityUser>(_userManager)
    {
        AllowOnlyAlphanumericUserNames = false
    };
}

If you are using IOC of some sort ( I am using StructureMap) in your account controller, you will need to apply the fix mentioned above by Hao Kung when the Usermanager is passed in: (I had to). There may be a way to do it in the IOC setup, but I don't know how.

public AccountController(ApplicationUserManager userManager)
    {
        _userManager = userManager;
        _userManager.UserValidator = new UserValidator<ApplicationUser>(_userManager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };

Answer 5

If you cannot find IdentityConfig.cs then replace your AccountController constructor with this code.

public AccountController(UserManager<ApplicationUser> userManager)
{
UserManager = userManager;
UserManager.UserValidator = new UserValidator<ApplicationUser>(UserManager) 
  {
      AllowOnlyAlphanumericUserNames = false  
  };
}

Answer 6

As you will have probably found out (and was to be expected), ASP.NET Identity 2.0.0, released March 2014, adds this functionality in the framework.
