-# The local Docker environment will try to use the database software's default authentication plugin whenever possible.
-#
-# One exception to this is using PHP 7.2 & 7.3 in combination with MySQL >= 8.0. These versions of PHP lack support for
-# MySQL's caching_sha2_password plugin, which was made the new default in MySQL 8.0.
-#
-# Until MySQL 8.4, this could easily be changed using the --default-authentication-plugin with the old value of
-# mysql_native_password.
-#
-# In MySQL 8.4, the  --default-authentication-plugin option was removed in favor of --authentication-policy and
-# mysql_native_password was disabled by default.
-#
-# When mounted to the database container in the local Docker environment, this file turns the old authentication plugin
-# back on so that PHP 7.2 & 7.3 can be used in combination with MySQL 8.4.
-#
-# MySQL 9.0 will remove mysql_native_password.
