Multiple login entities and multiple level access permission in asp net mvc 5

Introduction

When developing a web application ASP.NET MVC 5, it is common to have multiple login entities and multiple levels of access permissions. This article aims to provide a solution to this problem by demonstrating how to implement multiple login entities and manage access permissions in ASP.NET MVC 5.

Step 1: Database Design

The first step is to design the database schema to accommodate multiple login entities and their respective access permissions. For , let's consider a scenario where we have two login entities: “Admin” and “User”. We can create a table called “” with such as “Username”, “Password”, and “Role”. The “Role” column will determine the access level of the user.


CREATE TABLE Users (
    Id INT PRIMARY KEY,
    Username VARCHAR(50),
    Password VARCHAR(50),
    Role VARCHAR(50)
);

Step 2: Authentication and Authorization

Next, we need to implement authentication and authorization in our ASP.NET MVC 5 application. We can use the built-in ASP.NET Identity framework for this purpose. The framework provides a flexible and secure way to manage user authentication and authorization.

To enable ASP.NET Identity, we need to modify the “IdentityConfig.cs” file in the “App_Start” folder. We can add the following code to the user manager and role manager:

Step 3: Implementing Multiple Login Entities

Now, let's implement the multiple login entities in our ASP.NET MVC 5 application. We can create separate controllers and views for each login entity. For example, we can have an “AdminController” and a “UserController”. Each will handle the authentication and authorization specific to its login entity.

In the “AdminController”, we can add the following code to authenticate and authorize the admin user:

Similarly, we can implement the authentication and authorization logic for the “UserController” as well.

Step 4: Managing Access Permissions

To manage access permissions, we can use the “Role” column in the “Users” table. We can assign different roles to different users based on their access level. For example, we can assign the role “Admin” to admin users and the role “User” to users.

In the controllers, we can use the “Authorize” attribute to restrict access to actions based on the user's role. For example, in the “AdminController”, we can add the following code to restrict access to the “DeleteUser” action to only admin users:


[Authorize(Roles = "Admin")]
public ActionResult DeleteUser(int userId)
{
    // Logic to delete user
    return RedirectToAction("Index");
}

Similarly, we can add the “Authorize” attribute to other actions in the controllers to manage access permissions.

Conclusion

In this article, we have discussed how to implement multiple login entities and manage access permissions in ASP.NET MVC 5. By following the steps outlined above, you can create a secure and flexible web application that supports multiple login entities and different levels of access permissions.
