本文介绍了当使用旧版客户端连接到MySQL 4.1及以上版本服务器时遇到的认证错误，并提供了几种解决方案，包括升级客户端、使用旧式密码或通过特定命令重置密码。

Client does not support authentication protocol
Client does not support authentication protocol

MySQL 4.1 and up uses an authentication protocol 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 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 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:

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

Alternatively, use UPDATE and FLUSH PRIVILEGES:
