connect problem after upgrade to 4.1

[Richard]

Hi,

I upgraded from MySQL 4.0 to 4.1. The server is running on windows.
At the command line and using MySQL Administrator or MySQL Control Center a can access the database. But I get the next error when I try to run a Perl script I was using before.

[Tue Aug 10 06:15:17 2004] [error] -352317: ModPerl::Registry: DBI connect('host=Pc2;database=zoek','tester',...) failed: Client does not support authentication protocol requested by server; consider upgrading MySQL client at C:/xampp/htdocs/modperl/indexer.pl line 52\n

And this is what I used in the Perl script:

use DBI;
$db = DBI->connect("DBI:mysql:host=Pc2;database=zoek","tester","test",
{PrintError => 0, RaiseError => 1});

Does anybody has an idee what to do?

Richard
