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.
• When connecting to the server with a pre-4.1 client program, use an aclearcase/" target="_blank" >ccount that still has a pre-4.1-style password.
• 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:
