First, ensure that you are aware that the userid/passwords are case sensitive.  Ensure that your caps lock isn't on (or is on, if that's how you first set things up).  Should you want to reset the passwords,   reboot the machine and at the grub prompt, select the options for "kernel options".   Add the word "single" to the kernel parameters.  You'll be brought up in single user mode.  (with a # prompt)

Type:   passwd,  then follow the prompts to reset your root password.    If you want to change the user, type  passwd username   (where username is the user you want to change) and do the same thing.

Now, type "init 5" and you'll be brought up in graphical mode (or "init 3" for text).

Try logging in again.   If you still have problems then post again with the exact procedure you are using.

yap,

1. no Caps Lock
2. Username and passwrd are 100 correct
3 already did reboot with "single" option and changed both user passwrd as well as root password ... but still both not working

http://www.linuxforum.com/redhat/s1-q-and-a-linux-single.html

this is how i cahnged my password for root as well as the user i had made. Still when i login as root with the password i just changed it says Autinication Failure ... if i cahnge anything, or type wrong says incorrect user or password.

now what do i do?
