• Strong Certificate Mapping in Active Directory with Richard Hicks

  Are you using strong certificate mapping in Active Directory? Richard Hicks returns to the show to talk about the impacts of KB5015754, issued way back in 2022, and how it turned into an enforcement event on February 11, 2025 that might have caused some serious problems for folks trying to authenticate to Active Directory. For most sites, the upgrade to strong certificates was pretty much automatic. But if you're using Intune SCEP, you needed to do some configuration - and if that was missed, there is trouble. There are workarounds for now, but come September 2025, enforcement will be mandatory and everything gets harder, so it's worth looking into it now!LinksKB5015754: Certificate-based Authentication Changes on Windows Domain ControllersRichard's Blog Post on Strong Certificate Mapping EnforcementActive Directory Certificate ServicesCreate and Assign SCEP Certificate Profiles in IntuneHeartbleedRecorded February 17, 2025

• Managed DevOps Pools with Eliza Tarasila

  How do you manage your CI/CD pipeline resources? Richard chats with Eliza Tarasila about Managed DevOps Pools in Azure DevOps. Eliza tells the story of discovering that teams were using Azure DevOps internally at Microsoft but would need to build their tooling to stand up the resources for testing and deployment. Managed DevOps Pools became the standard way to specify resources like virtual machines and assign them to projects so that they would start up automatically. The resources in the pool can be custom resources in Azure or even on-premises servers! And, more importantly, you don't need to care and feed for the infrastructure used in the pipelines, Azure DevOps will do it for you.LinksAzure DevOpsCreate and Manage PoolsManaged DevOps Pool Origin StoryAzure DevOps PricingAzure Spot Virtual MachinesManaged DevOps Pools DocumentationRecorded January 6, 2025
