Some of You may have encountered a small problem while installing openSUSE (i did it with the x64 DVD version). After all the configuration You finish suse tries to put You to a login prompt without restarting the computer right??
And You try to login twenty times and You are quite sure it’s the password You entered, well it might be correct but not now 
Just restart the computer and take the DVD out. It will tell You that configuration failed and will start again, fortunatelly after that You’ll be able to login with You password (it won’t ask for new password or users settings). Enjoy, hope I helped a bit:D
