How to reset the local SSO admin account on vCenter 6

Windows

From an elevated command prompt, run:
“%VMWARE_CIS_HOME%\vmdird\vdcadmintool.exe”
Choose option 3.
Type “administrator@vsphere.local” (or your custom suffix)
And copy the new generated password, then login via the webclient to change.

If you get the following error “VmDirForceResetPassword failed (5)” then login as the local windows administrator account and retry. This is a known issue.

VCSA

SSH to the appliance as root.
Run “shell.set –enabled true”
Run “/usr/lib/vmware-vmdir/bin/vdcadmintool”
Type “administrator@vsphere.local” (or your custom suffix)
And copy the new generated password, then login via the webclient to change.
