VMWare - resetting admin@system-domain password

[varkanoid]

any vmware experts out there ?

Somehow our SSO master password has been changed. admin@system-domain account. Its not the one I have recorded and no one else has access to the VM platform.

I followed the vmware KB to reset it

Login as an administrator to the vCenter SSO server.
Click Start > Run, type cmd, and click OK. The Command Prompt window opens.
Navigate to the directory SSOInstallDirectory\utils. By default, the installation directory is C:\ProgramFiles\VMware\Infrastructure\SSOServer\utils.
Run this command:

rsautil reset-admin-password
Enter the master password when prompted.

Note: This is the password selected for the SSO administrator during the SSO installation. If you have changed your SSO administrator password later, the master password is still the original one chosen.

however I get this error which I have googled but the only answer I can find is to reinstall SSO which I dont really want to do if I can help it.

ERROR: Invalid password, failed to decrypt system key
Root cause: javax.crypto.BadPaddingException: Given final block not properl
padded

So I tried the other method mentioned in the KB

On the vCenter Server Appliance
Log in as root to the vCenter server Appliance.
From the command line, navigate to /usr/lib/vmware-sso/utils directory.
Run ./rsautil reset-admin-password.
Enter the master password when prompted.

Note: By default, this is the root password.

Enter the SSO administrator name for which you want to reset the password. For example, admin.
Enter the new password for the user and then reconfirm the same. Ensure that the new password is compliant with VMware's list of unsupported character.

however the vmware-sso folder is missing off the host ! I've also googled this and it comes up with nothing.

Any ideas why the vmware-sso folder is missing off the ESxi host and how to get it installed ? (vsphere 5.1).

Very strange.

this post can be closed I found out Vsphere 5.1 doesnt have SSO integrated.
