Now I just know that I’m typing in the password correctly. I mean, I did just make it 10 minutes prior to this! But whatever the case, I can’t get in. So now I need to reset the password on the SSO admin account. Here are the steps to do just that.

First, open an elevated command prompt from the vCenter server and browse to the “C:\Program Files\VMware\vCenter Server\vmdird” directory


From there, run vdcadmintool.exe. Select option 3 to use the Reset Account Password tool


Enter the SSO admin account here:


A new password will be generated that you can use to login with


Now go and login as the SSO admin and change the password to something you can remember this time! 😉

One more thing….

If you need to reset the SSO admin account and you are using the VCSA (vCenter Server Appliance) then:

  1. Connect to the VCSA via SSH
  2. Open vdcadmintool located at: /usr/lib/vmware-vmdir/bin/
  3. Continue with the rest of the steps as if this was the Windows install
