I had this issue when running a pre-release version because I did not RTFM and missed the default password in the doc. We've discussed how this should be in the future and I believe Dennis is on his way to resolving that in a later release (allowing you to specify your own password at deployment).
As for the lockout, its frustrating, and I'm not sure how long the lockout stays in place for but I know when it locked me out (late at night) I was able to login in the morning. So, it WILL eventually unlock, I just don't know what the timeout is set to currently
Huge step forward!
It might be more convenient to have all 3 items zipped up to facilitate a single download.
Additionally I am hoping that a locked account would unlock after a while to retry passwords rather than constantly having to redeploy an appliance. Can this maybe be clarified in the release notes?
