Answer 1

In phpMyAdmin, setting the session variable will work, but the call to the password function must occur in the same session/execution.

For example, if I execute:

SET SESSION old_passwords = 0;
SET PASSWORD = PASSWORD('notagoodpassword');

It will correctly set it.

Answer 2

SOLVED!

Although the SET SESSION old_passwords=0; wasn't working in phpMyAdmin.

I downloaded the MySQL GUI Tools and used the MySQL Query Browser to execute the same command on non-DBO user:

SET SESSION old_passwords = 0;

SELECT @@global.old_passwords, @@session.old_passwords, Length(PASSWORD('abc'));

now returned:

1      0      41

So I simply changed the password:

SET PASSWORD = PASSWORD('my_old_password')

And now PHP 5.4 PDO connects to the database with that user!

Answer 3

this solution worked: SET SESSION old_passwords = 0;

BUT: I had to drop the "old" userfrosting table afterwards and create it new - then it worked like a charm.
