This error is occurring because you are using the new password
encryption that comes with MySQL 4.1, while your
<code class="filename">DBD::mysql</code> module was compiled against an
older version of MySQL. If you recompile <code class="filename">DBD::mysql</code>
against the current MySQL libraries (or just obtain a newer version
of this module) then the error may go away.
</p><p>
If that does not fix the problem, or if you cannot recompile the
existing module (e.g. you're running Windows) and/or don't want to
replace it (e.g. you want to keep using a packaged version), then a
workaround is available from the MySQL docs:
