It’s been too long since I wrote up a how-to article. But this one came from a really interesting problem. My colleagues were recently faced with an issue at a site where the customer wanted to upgrade from vSphere 5.1 to 5.5. Which was fine, but they’d forgotten / misplaced / couldn’t remember the SSO master password. So I’ve added a brief article covering the steps involved in getting it sorted out. Full credit to Michael, Vincent and our Partner SE Charles for piecing together the steps. I’m really just the messenger.
While you’re there, have a look through my other articles. While dated, some are still useful.
