After realising that I should really enable comments in my last post, I set out to do so in a way that fits my personal requirements. At the outset, the most obvious solution was adding Entra External ID Authentication and user management (as one does 😉). Entra External ID is a version of Entra ID... » read more
Windows 365 (and Azure Virtual Desktop) Conditional Access Deep-Dive Recently, I had the pleasure of troubleshooting Windows 365 Single Sign-On (SSO) – the issue was quite odd. When you open the Windows 365 website (windows365.microsoft.com) or the "Windows App", authentication is requested as expected. However, when establishing a session with one of the virtual desktops,... » read more
So – you have started testing “Require authentication strength”, as requested by Microsoft. But have you been receiving issue reports from partner organizations or guests who cannot switch to your tenant? Or maybe you are a Teams administrator that has been seeing reports that your users cannot Collaborate with a specific Organisation? From the other... » read more
From time to time, customers have the Ask to allow access to Microsoft 365 on devices not managed by their Organisation. Whether it is because of a bring-your-own-device (BYOD) strategy, the desire to access work files on the go, collaborating with guests, or a multitude of other reasons. Specifically for VDI: Allow use of the... » read more
There is no better indicator of how important AI has become to Microsoft than the frequency with which "Copilot" and "AI" are mentioned in the Book of News. And to be honest, it was so noticeable that I got interested in the trendline – the two other keywords are of course completely random 😉: Approach:... » read more
The Microsoft Build event is one of the most important events for developers and IT professionals worldwide. Each year, new innovations and technologies from the Microsoft ecosystem are presented. Although the focus is on developers, in the Microsoft Cloud world, practically all areas now seamlessly merge. Therefore, it is wrong to expect topics exclusively relevant... » read more
When I started learning Entra ID (then still Azure AD), my biggest challenge — aside from the seemingly endless products renamings in M365/Azure — was that "SSO" (= Single Sign-On) has almost become a buzzword. If you are currently looking for ways to standardize ldentities and less frequently interrupt a users work for logins, you... » read more
At time of writing (April 2024), adding and using Enterprise Applications in Admin Units is not Supported by Microsoft yet. In fact, I am not aware of any official Previews. This Article is purely me playing around, if you use any of this in Production it’s on you. I have written quite a few Articles... » read more
While working on my appeal against Application.ReadWrite.All, I stumbled upon a potential way to rotate an application’s authentication certificate without Graph API permissions. After some experimentation, I was unable to get it running in PowerShell, so I set it aside for the time being to finish the article. However, the topic continued to intrigue me,... » read more
When Microsoft first disclosed the January Midnight Blizzard attack and posted their subsequent deeper analysis I followed the resulting content with great interest – risks posed by Enterprise Applications are a topic near and dear to me. I will try to keep this article standalone, but it might be a good idea to skim the... » read more
This article is the practical part of the Theory – for the answer to the question "What’s the purpose of all this?", please refer to that Article. To ensure I’m not seen as someone who says "someone should" and then does nothing, here follows a (by my standards) "quick" proof of concept on how password... » read more
In my work on the practical implementation of Password Rotation without Privileged Authentication Administrator, I stumbled upon a somewhat extensive challenge. When trying to use PowerShell to sign in to the Graph API using username + password, I couldn’t find a combination in the PowerShell SDK. The only method would be ClientID + Secret –... » read more
