Azure B2B and internal applications

Azure Active Directory released the functionality for B2B a few months ago. This new feature enables companies to extend their identity service as well as their applications beyond traditional borders. Say, you want to provide your vendor a mailbox in YOUR Office 365 tenant. That way the vendor can still read/write emails on behalf of […]

Enabling on-premises MFA in AAD : when it just doesn’t work…

When you want to enable MultiFactorAuthentication (MFA) for Azure / Intune / Office 365 / Dynamics 365 and you are using federated logins and want to have the MFA provider to be on-premises (integrated with ADFS/PingFed/other) integrated.. you might run into an issue where the Azure MFA page keeps popping-up and asking you to register […]

Add disks to VMs in Azure

Sometimes you have the need to add additional disks to VM’s in Azure.. and if you happen to manage a big farm of servers and all servers need to have additional disks, you find yourself in the portal a lot.. or in Powershell hacking your way through variables and collections..

This script will help you adding one or multiple disks to a single VM, all VM’s in a ResourceGroup or all VM’s in a ResourceGroup starting with a particular name (more…)

Unused Azure Resource cleanup

When using Azure as your development platform, or to play with.. you eventually find yourself deleting resources 1 by 1 or entire resource groups.. cause when you delete a VM in ARM (the new portal), it deletes only the VM, but leaves the VHD, the NIC, the public IP, and NGS’s… so what if you could run a script that looks at the unused resources and deletes them for you?

well, look no further.. (but develop with me, based on) the initial script I wrote.. AzureCleanUp.ps1

PowerBI Gateway and Proxies

The PowerBI Gateway can be used to connect on-premises database sources into PowerBI, Microsoft Flow, Logic Apps and PowerApps. The advantages are many, and if installed correctly it will work flawlessly. However, the default install of the connector is based on the gateway being able to connect directly to the internet. While it’s the fastest […]

UPN Change of user not updated in AAD (O365/Intune/other)

When you want to change the user UPN, in certain conditions, this UPN change will not be synchronized to AAD (Office365/Intune/other).. why?

When you have federated domains for Office 365, or rather AAD in general and you want to switch your users from one domain to another, you will notice that that object will replicate anymore to AAD (and thus Office 365). I noticed this a long time ago, and it seems Microsoft now also posted this as a known KB a few weeks ago..

Selective password synchronization with AAD-Connect

In my previous post, I talked about the possibility of using Kerberos Constraint Delegation to avoid having passwords in AAD. However, sometime you want to have a few passwords in AAD-Domain Services to ensure that administrators can still login to the VM’s interactively (RDP) or users are able to use certain services that are not published with Kerberos or aren’t web services.

In this post we will look at editing the configuration of AAD-Connect to synchronize the passwords* of users that have an attribute in AD present so that some users (like administrators) will be able to login to VM’s joined to AAD-DS using their on-premises passwords.

* see note below

When you have ADFS hosted on Azure (as per my previous post), you might want to look at using Traffic Manager and then especially the probes and the endpoints..

So, this post is to help you to configure ADFS behind the Azure Traffic Manager and ensure proper failover on service unavailability.

AAD-DS + KCD-PT + Federation (or how to avoid passwords on the cloud)

New (and only available within Azure) are the Azure Active Directory Domain Services. This service is based on Azure Active Directory and the data replicated into it. It provides Domain Services as a service to subscription administrators and can be very useful for many scenario’s where domain services are required, but security or management of domain controllers in the cloud is a concern.

In many documents, you will see that you need to replicate user password [hashes] into AAD to make it fully work.. but this post is about how you can avoid that using Kerberos Constraint Delegation with Protocol Transition….

Redundant SRX Junos to Azure VPN with VNET Peering

Ever since playing with BGP I was looking for a way to make redundant tunnels. As the local internet provider here would only allow me a single IP address, I looked at the other side. What if we have two Azure regions that have a VPN tunnel to my SRX and between each other. Routing would be dealt with by BGP and thus, I should be able to connect to both VNET’s through each of the VPN tunnels.
