Thanks for sharing. Keep in mind that to use that reset util requires that you already know the admin@system-domain password. If you know it, then you can reset it easily. That process is well documented in the official VMware KB. Most folks here simply don't know the original password so cannot reset it like that.
As such, the only real fix thus far has been performing the DB hash technique.

Unrelated Note: Please be advised that my original concern from earlier in the thread about the admin@system-domain password being in plain text was incorrect. I think the only plain text password stored is that of the RSA_User which does not help in recovery unless all passwords were set exactly the same at install time. The location of that plain text password (which was originally "intentionally deleted" by me) is "C:\Program Files\VMware\Infrastructure\SSOServer\webapps\lookupservice\WEB-INF\classes\config.properties". Again, this likely won't help anyone who has forgotten the admin@system-domain password, and the fix is still to perform the DB hash technique noted from the shubis blog in germany.
