For some reasons we have very old hard and software here at work.
I had the problem that we’ve upgraded our database servers from MySQL 4.x to MySQL 5.x.
But there is a very old provisioning tool which does not support PHP5 and so we’re stuck with an old PHP4 and a new MySQL 5 Database.
If we try to connect to the database the following error occures:
PHP Warning: mysql_connect(): Client does not support authentication protocol requested by server;
I know, the only correct way is to change our program to support PHP5, but there are no resources left for this change and this is not my decision.
