I am installing Coppermine on a MySQL database through an ISP, so I have to go through them for any global or root settings change.

When the Copermine installer (new or classic) goes to check the MySQL database identity, user, and password I typed, the response is:

Could not create a mySQL connection, please check the SQL values entered
MySQL error was : The server requested authentication method umknown to the client


The MySQL doc at https://dev.mysql.com/doc/refman/5.5/en/old-client.html says this is a mismatch between MySQL client and server versions that hits the change to longer password hashes. 

It suggests that I need to have my ISP login to my database with root privilege and, with appropriate substitutions, execute:
SET PASSWORD FOR 'some_user'@'some_host' = OLD_PASSWORD('newpwd');


PHPINFO says my client version is MySQL 5.0.10 20111026.
Running select version() in MySQL says 5.5.31.

Getting the ISP to act on a request like this in a timely way is a pain.  So, I want to be sure that what is suggested is reasonable and may actually solve the problem so I can proceed with the Coppermine install.

Has anyone encountered this before?  How did you solve it?  Is there another workaround?  Thanks!

It really is something only the ISP can adjust. If you are running into problems with just the installer you are sure to hit more when you start using your gallery.

You are proabibly mistaking something.
Is best to create new database in your cpanel with a password and username and on the installer.php you use that database password and username.

Can you add more details?

That often causes problems later on if the server setup is poor. Often seen during updates or when installing certain plugins.
