Disable vSphere SSO – Reg Hack

DISCLAIMER: This ‘hack’ is UNSUPPORTED and should never be used in a Production Environment – for home labs though may  be useful!

Whilst experiencing an issue with a corrupt SSO installation in vSphere 5.5, I discovered a reg hack that allowed me to continue to login to a vSphere environment with domain credentials until I could resolve the existing issue with SSO. This is a simple change and involves editing the vpxd.cfg file.

  • On the vCenter server navigate to vlxd.cfg file
    • For Windows 2003: C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\vpxd.cfg
    • For Windows 2008: C:\ProgramData\VMware\\VMware VirtualCenter\vpxd.cfg
    • For the Appliance: /etc/vmware-vpx/
  • Open vpxd.cfg in a text editor
  • Search for the following:

  • Change ‘true’ to ‘false’ between the highlighted tags
