Just got my own mysql server going, and am attempting to run a flash/php mysql form that I had running perfectly on another server.

On my server I am getting this error…

Client does not support authentication protocol requested by server; consider upgrading MySQL client

Wondering if anyone has ran into this problem, and would apprectiate some guidance! thanks!
