VMware vCenter Smart Card Authentication Stops Working after Upgrading to 7.0 U3i

Reading time: 3 minutes
After testing a recent upgrade to VMware vCenter Server 7.0 Update 3i, I encountered an issue where the vCenter Server would no longer authenticate users via smart cards/X.509 certificates. The vCenter Server would not even request a certificate from the client’s browser anymore. This seemed odd as the functionality worked fine on the previous 7.0 Update 3h. Surely VMware wouldn’t make a breaking change within a minor patch release? After reverting the upgrade and testing that it wasn’t an issue with the upgrade process itself, a support ticket was opened with VMware support.

Unable to Log In to Orchestrator Control Center in vRealize Automation 8.x

Reading time: 2 minutes
Recently, while attempting to change some settings on several instances of vRealize Orchestrator embedded within vRealize Automation 8.8.1 appliances, I found that I could not successfully authenticate to the vRealize Orchestrator Control Center interface. The interface is located at https://[vRA URL]/vco-controlcenter and requires that you provide the “root” user credentials to access it. Although I could authenticate to the virtual appliance consoles using the “root” credentials, I could not successfully authenticate to the vRealize Orchestrator Control Center interface.

Introduction to vSphere Diagnostic Tool

Reading time: 3 minutes
While browsing the VMware Flings website, I recently ran across a Fling previously released in November of 2021 titled vSphere Diagnostic Tool that I found to be quite interesting. The tool is a set of python scripts that execute various diagnostic commands against a vCenter Server appliance. The scripts aim to rapidly isolate common known issues with vCenter Server appliances to aid and provide the end-user with information on how to remediate the problems.

ESXi Upgrade - Software or system configuration of host is incompatible

Reading time: 2 minutes
While attempting to upgrade my ESXi hosts to the latest vSphere 7.0 release, I ran into the following error on all of the hosts in my home lab: The upgrade has VIBs that are missing dependencies. Remove the VIBs or use Image Builder to create a custom upgrade ISO image that contains the missing dependencies, and try to upgrade again. While the error message gives you a pretty good idea of what might be causing the issue, for the life of me, I couldn’t think of what VIBs it could be referring to.
