[TYPO3-english] Typo3 backend admin panel login error

[Ramaraju Musku]

Hi all,
While we accessing typo3 backend admin panel we get the following error after giving right user name and password.
"Your login attempt did not succeed. Make sure to spell your username and 
password correctly, including upper/lowercase characters. "

We have changed password in database table be_users. but no luck.
Please help this issue.
Thanks,
Ramaraju.
