Changes to vSphere Client Login UI customizations in vSphere 6.7

by // 11 Comments

For those that have customized their vSphere Client Login UI using the instructions here and here, it looks like the process can not be applied to the vSphere 6.7 release. From what I can tell, it looks like we have now consolidated the various WAR files into a single file /usr/lib/vmware-sso/vmware-sts/webapps/ROOT.war. The original contents of the websso directory, which pertains to the UI customization, is now located here. This was a fairly minor change, but something to be aware of and for details on how to persist your configuration changes, please see the instructions below.

UPDATE (11/19/22) - As of vSphere 8, the webapp WAR file is now located in /var/lib/sso/webapps/ROOT.war

Disclaimer: This is not officially supported by VMware. If you decide to enable this, please use at your own risk and ensure you backup all original files in case you need revert back to the original configuration.

As part of looking into this, I also had some fun incorporating a cool little animated login page directly into the vSphere UI which I had shared on Twitter yesterday. Stay tuned for more details on #vYetti 🙂

vSphere Client Login UI customizations do not persist in VCSA 6.5 Update 1

by // 3 Comments

The much anticipated release of vSphere 6.5 Update 1 just GA'ed late last week and like many in the community, I also went ahead and upgraded my home lab to this latest release. vSphere 6.5 Update 1 contains a ton of fixes as well as several new capabilities which you can read all about in the release notes here and here.

One neat little trick I take advantage of in my lab environments when deploying the vCenter Server Appliance (VCSA) is actually pre-filling out the credentials for the vSphere Client UI (not recommended for production environments of course) which I had blogged about here a few years back. Sine I have many different environments for different scenarios, I find myself being lazy and having to type in the credentials to each one of these environments. Instead, I can pre-fill either the username and/or password (which I will stress again, not recommended for production) within the vSphere Client Login UI page which is simply just using HTML.


After making the necessary changes to my VCSA 6.5u1 system, I needed to reboot my ESXi host and when everything came back up, I was surprised to find my changes to the vSphere Client Login UI had disappeared. It took me awhile to figure out why the changes were not persisting across reboots. There seems to be a change in behavior compared to prior releases of the VCSA (6.0 & 6.5) on when this capability was actually possible.
