IdentityServer Role and Policy Based Authentication

Last Updated: August 16, 2022

When we want to allow users in specific roles to access certain resources then we apply role based authentication. In the same way when users satisfying a policy are allowed to access certain resources then this is called policy based authentication. In IdentityServer, both role and policy based authentications can be implemented very easily.

This tutorial is a part of "IdentityServer with ASP.NET Core Identity" series and contains 3 tutorials, these are:
  1. ASP.NET Core Identity with MongoDB as Database
  2. IdentityServer with ASP.NET Core Identity and MongoDB as Database
  3. IdentityServer Role and Policy Based Authentication

IdentityServer with ASP.NET Core Identity and MongoDB as Database [Detailed Guide]

Last Updated: August 16, 2022

In this tutorial we will set up IdentityServer4 with ASP.NET Core Identity from absolute beginning. The ASP.NET Identity will be configured with a MongoDB database. When a client will come to IdentityServer4 for authentication, the client’ credentials, stored in the MongoDB database, will be checked by ASP.NET Core Identity. We are going to implement all this along with a Web API that will be secured with IdentityServer, so sit tight and enjoy this very long and detailed tutorial.

We will create a complete project from scratch and it’s source codes are given in GitHub repository.


ASP.NET Core Identity with MongoDB as Database {Detailed}

Last Updated: August 16, 2022

In this tutorial we will implement ASP.NET Core Identity with MongoDB as the database. So, the MongoDB will serve as the Identity Database instead of SQL Server. First, we will configure Identity to use MongoDB as the database and after that create an example project where Identity Users and Roles will be created. In the end, Login and Logout feature will be added so that users can be authenticated to secured portions on the website.

Kubernetes Persistent volumes (PV) and Persistent Volume Claim (PVC)

Last Updated: June 28, 2021

Persistent Volumes (PV) are storages in the Kubernetes cluster which are persistent in nature. The PV has a lifecycle independent of any individual pod which is using the PV. A Persistent Volume remains outside the Pod unlike emptyDir volume (emptyDir remains inside the Pod) so even if a Pod crashes there is no risk of the volume getting ruined.
