When I type my username and password into the login field, I receive the following error:

Login incorrect

How can I solve this problem? I am using CentOS.

Can you log in as root? If you can't, and you're absolutely sure you typed the username and password correctly, boot into single user mode, run openvt -s login, try to log in, and look in the system logs for more information. – Gilles Apr 22 '11 at 19:54
@Gilles - thanks for your answer. – Cell-o Apr 23 '11 at 13:18

In all likelihood you are not giving the right username and password. Are you sure your keyboard layout is the same and you didn't have CapsLock on when you saved your password?
