You never know with so called "tests". However, on newer machines, if a root account is present (which it does NOT have to be on newer Solaris, and such will be the case with Solaris 11), often times a password IS required or the account is not valid. So.. not sure what the test is looking for. In the old days, clearing out the root password was the easy way to break into a box for which the root password had been forgotten. You simply mounted up the filesystem (different box, or same box with a bootable CD) and took at the password hash for root. But on some newer OS's, non existent passwords are not allowed... well, they are allowed but the result is a locked account.... I'd have to google around to see what Solaris does now... but who knows what the "test" is looking for.

In OpenSolaris and future Solaris 11, root becomes a role and NOT an account by default... but it can easily be added for compatibility with the plethora of sw, etc. that still needs a root account.
