Running an app under PHP 4.3.8 and trying to connect to a MySQL 4.1 database can be pretty frustrating. By default it gives you a message like this:
"Client does not support authentication protocol requested by server; consider upgrading MySQL client".
The problem is that by default PHP’s MySQL module is compiled with an older MySQL client library. MySQL has a manual page about this.
I use the OLD_PASSWORD method. I connect to MySQL under root with MySQL Query Browser and I issue the following command:
set password for 'demouser' = old_password('demopass');Comments from long ago:

Due to a time crunch I almost revererted to the 4.0*. Instead, now I get to use 4.1, which matches my production environment

Note: When using a newer client library (like the mysql command line tool provided with the 4.1 server), you can connect to older servers and use either the old or the new authentication protocol.
