Client does not support authentication protocol requested

i psoted a message here before few days asking how to solve this problem, fortunately i found the solution on a website, i reseted the pass and all worked. MySQL 4.1 uses an authentication protocal based on a password hashing algorithm that is incompatible with that used by older clients. If you upgrade the server to 4.1, attempts to connect to a it with an older client may fail with the following message: shell> mysql Client does not support authentication protocol requested by server; consider upgrading MySQL client To solve this problem you should do one of the following: Upgrade all client programs to use the 4.1.1 or newer client library. Use a user account with an old password when connecting from a pre 4.1 client. Reset the user that needs a pre-4.1 client to use an old password: mysql> UPDATE user SET Password = OLD_PASSWORD('mypass') -> WHERE Host = 'some_host' AND User = 'some_user'; mysql> FLUSH PRIVILEGES; Tell the server to use the older password hashing algorithm: Start mysqld with --old-passwords. Set the password for all users that has a long password. You can find these users with: SELECT * FROM mysql.user WHERE LEN(password) > 16; Do you Yahoo!? Yahoo! Finance Tax Center - File online.
