title: azure AD Security groups of a User
body: <p>I am trying to get all of security groups of Authenticated user as in the example <a href="https://github.com/Azure-Samples/active-directory-dotnet-webapp-groupclaims/blob/master/WebApp-GroupClaims-DotNet/Utils/ClaimHelper.cs" rel="nofollow">Github example</a>, and it works for many people, but for one man it does not work. He has 403 error (forbidden) when the app requests his groups (lines 43-49). I am a beginner with the azure ad, and what can be a reason of this situation? All of other people a prepared correctly as in this example. Thanx a lot.</p>
