"mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client"
Posted by: joape382
Date: November 20, 2004 04:28AM

I get the following error trying to access the MySQL 4.1.7-nt database:

Warning: mysql_connect(): Client does not support authentication protocol requested by server; consider upgrading MySQL client

What does this mean? What exactly is the MySQL client? Is that my php engine? I'm somewhat used only to version 3.x and have just installed this version of MySQL. Can someone please help me to solve this problem? Joachim
