Unless it's been secured, you can probably boot using the miniroot on the installation media, go to the password file and clear the root password and save.
Restart that Indigo, and log on as root, no password.
When doing various services on these machines, I would keep a drive ready to boot miniroot. Would clear the root password, archive the hash, then do the work, put it back and on to the next gig. Most of the time nobody even knew what that password was.
Took {big company IT} quite a while to finally call and ask how those services were getting done...
