The MySQL standard documentation provides the answer to this. In short:

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 account 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:

See http://dev.mysql.com/doc/refman/5.1/en/old-client.html for a detailed explanation and solution.
