Azure Active Directory

V1 and V2 Identity and Access tokens with Azure Active Directory

This has caused me a ton of confusion and my customers keep getting confused as well. Azure Active Directory has been around for some time now. Some time ago we added a new endpoint (V2) which is more standards compliant and supports both AAD and MSA accounts and for example features like incremental consent. Still people get confused about our numbering scheme and I totally understand why. Let me try to explain a little bit how this all works.

Authenticate an Azure AD user with SAML for ASP.NET Core

The other day I needed a test application to try something with SAML support in Azure Active Directory. I started looking how to configure an ASP.NET Core webapplication to support SAML. It’s very easy to set it up for OIDC authentication but I found out ASP.Net (core) doesn’t support SAML out of the box.

Create a user delegated permission and an application permission with the same name in Azure Active Directory

For a training we are delivering I tried to create a little sample where I show how to create an API and protect it with our Microsoft Identity Platform. We have 2 kind of permissions we can support with our consent and permissions framework. User delegated permissions and application permissions. This is what we use for MS Graph as well. User delegated permissions are used if you want to grant the app running the permissions in name of the user.

Configure Domain_hint in asp.net core

This took me way to much time to figure out since there is a ton of old information on the internet. I wanted to change the default behavior when people are logging in to my ASP.NET Core website using Azure Active Directory (or Microsoft Identity Platform). After some searching I figured out how to change this setting. You have to add the following piece of code to the ConfigureService method in your Startup.
