create ASP.net MVC framework web application

select individual accounts in Authentication

create project

change connectionString to 

 

Rename table names

goto IdentityModels.cs file 

paste below code in ApplicationDbContext class

protected override void OnModelCreating(DbModelBuilder modelBuilder) { base.OnModelCreating(modelBuilder); modelBuilder.Entity().ToTable("Users"); modelBuilder.Entity().ToTable("Roles"); modelBuilder.Entity().ToTable("UserLogins"); modelBuilder.Entity().ToTable("UserClaims"); modelBuilder.Entity().ToTable("UserRoles"); }

Now open packageManagerConsole and run these 3 commands

Enable-Migrations add-migration init update-database

it will create all user and auth related tables without ASPNET prefix

Now lets add Custom Fields to Users Table

goto IdentityModels.cs file 

type properties in ApplicationUser class as below

 

public string MobileNumber { get; set; } public string EmployeeNumber { get; set; }

Add new migration and update database by running below commands in Package Manager Console

 

add-migration mobileEmpFieldsAdded update-database

You will be able to see these fields in database Users table

now lets add these fields in RegisterViewModel and Register form

Goto AccountViewModels.cs in Models folder

and type new fields as properties in RegisterViewModel class as below (same as we added in ApplicationUser class

 

public string MobileNumber { get; set; } public string EmployeeNumber { get; set; }

now open AccountController goto Register postback method

add new properties in ApplicationUser new object as shown below before and after

 

//Before var user = new ApplicationUser { UserName = model.Email, Email = model.Email }; //After var user = new ApplicationUser { UserName = model.Email, Email = model.Email ,MobileNumber = model.MobileNumber,EmployeeNumber=model.EmployeeNumber };

Now Goto Register view page and add these inputs as

  

@Html.LabelFor(m => m.MobileNumber, new { @class = "col-md-2 control-label" })

@Html.TextBoxFor(m => m.MobileNumber, new { @class = "form-control" })

@Html.LabelFor(m => m.EmployeeNumber, new { @class = "col-md-2 control-label" })

@Html.TextBoxFor(m => m.EmployeeNumber, new { @class = "form-control" })

Now build your project, run it and try to register new user

new fields data (mobile & empno) will also be inserted in users table

now lets get these custom fields data from Identity object after login

for we have to make claims and extensions means our own functions like Identity.getMobile() and Identity.getEmpno()

to make claims go to IdentityModel.cs inside ApplicationUser class there is GenerateUserIdentityAsync method

before return there also a comment to add claims here 

add below code there

 

 

userIdentity.AddClaim(new Claim("MobileNumber", MobileNumber)); userIdentity.AddClaim(new Claim("EmployeeNumber", EmployeeNumber));

Now create a new class and name it IdentityExtensions

and add below code in this class

 

//using System.Security.Claims; //using System.Security.Principal; //make the class static public static class IdentityExtensions { public static string GetMobile(this IIdentity identity) { var claim = ((ClaimsIdentity)identity).FindFirst("MobileNumber"); // Test for null to avoid issues during local testing return (claim != null) ? claim.Value : string.Empty; } public static string GetEmployee(this IIdentity identity) { var claim = ((ClaimsIdentity)identity).FindFirst("EmployeeNumber"); // Test for null to avoid issues during local testing return (claim != null) ? claim.Value : string.Empty; } }

now go to views->shared->loginPartial.cshtml and at to write this

@using customAuth.Models   //replace customAuth with your project name

and now in content of page replaceUser.Identity.GetUserName() with User.Identity.GetMobile() or User.Identity.GetEmployee() and then run application login and see at top it will be showing hello your-mobile-number!

 

Now lets do manual login that is for lets say authenticate user with Active Directory and the authenticate that user without password

go to AccountController and then go to Login postback method and add below code

 

 

//comment below lines which is authenticating user with password //var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false); //switch (result) //{ // case SignInStatus.Success: // return RedirectToLocal(returnUrl); // case SignInStatus.LockedOut: // return View("Lockout"); // case SignInStatus.RequiresVerification: // return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe }); // case SignInStatus.Failure: // default: // ModelState.AddModelError("", "Invalid login attempt."); // return View(model); //} //instead of above lines write below code /*authgentication user with Active directory then with that email find a record in this site db and log him in manually consider we already authenticated with AD */ var user = UserManager.FindByEmail(model.Email); if (user == null) { ModelState.AddModelError("", "Invalid login attempt."); return View(model); } else if (user.LockoutEnabled == false) { return View("Lockout"); } await SignInManager.SignInAsync(user, false, false); return RedirectToLocal(returnUrl);
