Can't log in as root!


I've encountered a slight problem since I installed the final release of Mac OS X. I simply can't log in as "root"! The only response I get is "sorry". As far as I can remember, the root password is assigned at the same time as the admin password is first assigned. At least, that was how it worked in OS X PB... Is there anybody else who has encountered the same problem? Can this be fixed in some way?
