Azure Active Directory – How to give a Registered Application an AD Directory Administrative Role

By default a ‘Registered Application’ account is not a member of any Directory Roles and/or group memberships and there is no easy way to make these changes using the portal. You may have an API or back-end application that will be required to perform actions on your AD that requires elevated permissions (e.g. Reset passwords or delete accounts etc..)

Normally for advanced configuration, you will need to start editing the manifest file. Luckily this has been made easy using the Portal. You can now edit the file directly, or download, make changes and then upload.

However, to make a ‘Registered Application’ a member of a ‘Directory Administrative Role’ you need to use PowerShell to add the role member to the ‘Service Principal’ (as I couldn’t find a way to do this in the manifest!).

Azure Active Directory Graph API Wrapper to help make it a bit easier!

I have recently been trying to program against the Azure Active Directory (AAD) using the Microsoft.Azure.ActiveDirectory.GraphClient library. Unfortunately this library literally has no useful comments to assist understanding  or clarify parameters etc.. Let alone how best to use or implement objects and methods or what and why exception may occur.

Equally the MSDN documentation seems to be lacking in any examples and really has minimal comments (although I see it’s getting a bit better…I think).

To this end I have created a ‘wrapper / handler’ to simplify all sorts of AAD interactions called AADGraphHandler. It effectively will help manage the creation of the ActiveDirectoryClient and a bunch of it’s operations. You can find this on GitHub at https://github.com/nrogoff/AADGraphHandler

You can get access to the ActiveDirectoryClient directly, and so any methods not covered yet. (e.g. Adding and removing roles to a user. Just not needed it yet!)

Which alcoholic drinks have the most calories?

Which alcoholic drinks have the most calories?

I recently had a bet with some friends as to whether beer or wine would have the most calories by volume. So I did some research.

It turns out that pure alcohol is surprisingly high in calories on it’s own.

So there are 3 ways  we can break this down.

  • Calories per 100ml (per volume of liquid!)
  • Calories per serving (how many drinks you have?)
  • Calories per unit of alcohol (how drunk you get for each kcal?)
