php5

Hi. We're setting up a new webserver with PHP5.3 and are getting the "Error: could not connect: mysqlnd cannot connect to MySQL 4.1+ using old authentication ?" error message. After some google'ing I've found that we should set old passwords = 0 in my.cnf and reset the password(s). But we still have webservers running php 4.x & 5.2 that access the same mysql server (different users & databases), how will these be affected by this ? Will the mysql server be compatible with all the different PHP versions ?

Thanks.
