You are developing a WebAssembly authentication app and trying to implement Roles based access control. You are getting a similar error like… The WebAssembly Authentication stack appears to cast the roles claim into a single string. We need this User Factory to modify its behavior so that each role has its own unique value. Create the Custom User Factory First, create a custom User Factory (CustomUserFactory.cs)… Add the roles mapping…

Azure AD has a maximum number of groups that can be returned in an access token when you have selected to include the groups claim for your access token. This post will show you how to reproduce the scenario and then how to get the users groups using Microsoft Graph when a groups overage claim is present in the token instead of actual groups. For a JWT token, Azure has…
Read MoreControl access to your apps in Azure AD
We get this kind of question all the time. It comes in many variations and forms like… “I only want to consent for some users to access the app.” “I only want my service account to access this app” Before we get started… First and foremost, only consenting for allowed users is not the solution. This is not the purpose for consent. Consent is to inform a user or admin…
Read MoreConfiguring Options and MaxRetries for Graph Java Client
We have a great Java Graph SDK sample in our tutorial document located here. Pay special attention to the versions as not having the correct version of the prerequisites will give you difficulty! The sample will run a console application and uses the Oauth2 Device Code flow for authentication. Once it compiles and runs, you will get a message like this for the device code flow sign in: “To sign…
Read MoreHow to set your MSAL.js app up to automatically sign-in if you already have a session signed in on another tab
Our MSAL.js sample is an excellent example for using MSAL in a javascript page. However, it only demonstrates logging in by clicking on a button. If you’re launching your app from myapps portal or are otherwise already logged into the portal with the browser, it would make sense to just use that session to perform your sign-in for your MSAL app without requiring the button click. This is actually easily…

You are developing a Asp.Net OWIN or Asp.Net Core Authentication web application and integrating it with Azure Active Directory. You run into some issues during the sign-in process with no…
Read MoreWalkthrough: MSAL.Net client calling Azure API App with Easy Auth enabled in a B2C tenant
In a previous blog post, I talked about how to use MSAL.Net client application to call an Azure Function App with Easy Auth enabled in a regular tenant. In this post, I’ll describe the process to use an MSAL.Net client application to call a Web API application with Easy Auth enabled in a B2C tenant. I assume you already have an API App created on Azure App Service. If you…
Read MoreWalkthrough: Using MSAL.Net to call an Azure Function App with Easy Auth enabled
In this post, I’ll walk through the steps for how to create an application using Microsoft Authentication Library for .Net (MSAL.Net) to call an Azure AD protected Azure Function App using Easy Auth (Azure App Service’ Authentication and Authorization feature). 1. Create an Azure Function with Easy Auth enabled: Assuming you already have an Azure Function App created (refer to https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-function-app-portal if you don’t know how to create one), go…
Read MoreUnderstanding the difference between application and delegated permissions from OAuth2 Authentication Flows perspective
It’s well documented in the Permissions and consent docs and the Developer Glossary page that there are 2 types of permissions for an access token: delegated permission and application permission. In simpler terms, delegated permission is the permission granted to a signed in user while application permission is the permission granted to an application. The main difference between the two is that the former requires a user to sign in…
Read MoreConfiguring an App Service to get an Access Token for AAD Graph API
Introduction This post should show how to create an app service, configure authentication for the service, and then configure the authentication to get permissions to the AAD Graph API on behalf of the logged-in user. This post is an extension of the Azure App Service Token Store, the link to that can be found here. This is the entire setup scenario from scratch, starting with creating the web app, and…
