AZ Cleanup

I already published a script for cleaning up Azure resources, but found that with the introduction of the new AZ commands and later versions of the PShell CMDLets it was getting out of date fast. So I worked on a new module (.psm1) to replace it and give me more freedom to use the unused […]

F5 BIG-IP & AAD & KCD Simplified

With the release of an Application in Azure AD, the configuration of F5 publishing Kerberos backend applications have just been made a whole lot easier. This we cover in this post, but as an added bonus, the previous post adds the possibility of authenticating (Forest) trusted users on the same backend server using KCD (although […]

F5 BIG-IP & AAD & KCD – Cross Forest – Part 2

In the previous F5 posts we did, we always used a single forest, single domain setup. Obviously, this is not always the case, certainly when cross-forest migrations are being performed. Even in these situations we could leverage F5 and AAD’s federation capabilities to provide an SSO experience. Requirements: 2 Forests with a forest trust (two-way) […]

Enable/Disable Accelerated Networking on Azure VM’s part 2

In my previous post, I talked about using a custom script to redeploy VM’s with Accelerated networking enabled or disabled. The latest PowerShell cmd’lets however make things a lot easier and don’t require you to re-deploy the entire VM anymore. So, this post is a followup to the previous one and explains how to enable […]

One of the hottest topics with customers in their “journey” to adopt cloud is the topic of encryption. Data that goes up into space needs to be controlled to avoid leakage to hackers, script kiddies and what not. In the next few series I will be looking at Encryption in Azure, but let’s start with […]

Forcing re-authentication on (some) applications

Sign-In Frequencies in Azure AD: You might have seen on Azure Active Directory a new feature called Sign-In Frequency. In this post we are taking a closer look at this feature. First, we need to understand how authentication works and which tokens we are receiving. When you sign-in to an application which is dependent on […]

F5 Big-IP & AAD & BASIC / NTLM

In our previous post we looked at using Azure AD to perform the authentication for our F5 published web apps that used Kerberos. Now the strength of the F5 APM module is the SSO capabilities that allow it to authenticate users once and then they could reach any web app published by it, regardless of […]

F5 Big-IP & AAD & KCD

The title being full of acronyms, this topic is about publishing Kerberos based websites behind an F5 load balancer, while using Azure AD as the authenticating service. Or in more technical terms, F5 will rely on an external SAML based token to perform Kerberos Constraint Delegation towards a backend server. Get settled in, this is […]

ImmutableID – mS-DS-ConsistencyGuid – AADConnect – ADMT – part 3b

In part 3a, we explained how ADFS can be used in cross-forest migrations to ensure all users (migrated or not) can still authenticate. In part 3B we will be looking at Pass-Through authentication and how it affects migrated/non-migrated users. First of all, we need to make sure we have pass-through authentication agents deployed. In my […]

ImmutableID – mS-DS-ConsistencyGuid – AADConnect – ADMT – part 3a

To continue our coverage of ADMT and AAD, part three of the series. I know I promised 3 articles, but given the amount of data, I’ll split part 3 (authentication) in a few more posts.. We have 1 AAD and 2 AD’s; FORESTOOT.local as the source and TARGET.local is still the target AD forest. There […]
