error database

when i search in mysql.com there are alternative

"Client does not support authentication protocol requested
by server; consider upgrading MySQL client"

To solve this problem, you should use one of the following approaches:

* Upgrade all client programs to use a 4.1.1 or newer client library. (already now i using MySQL version 4.1.22-standard)
* When connecting to the server with a pre-4.1 client program, use an account that still has a pre-4.1-style password. (i don't know that meaning ;( )
* Reset the password to pre-4.1 style for each user that needs to use a pre-4.1 client program. This can be done using the SET PASSWORD statement and the OLD_PASSWORD() function:

mysql> SET PASSWORD FOR
-> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');

Alternatively, use UPDATE and FLUSH PRIVILEGES:

mysql> UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')
-> WHERE Host = 'some_host' AND User = 'some_user';
mysql> FLUSH PRIVILEGES; (i don't know that meaning ;( )

Substitute the password you want to use for “newpwd” in the preceding examples. MySQL cannot tell you what the original password was, so you'll need to pick a new one.

please help..

sorry about mis-thread..
