+  summary: "An application is unable to authenticate with the MySQL database because the user account is configured with an incompatible authentication plugin."
+  story: "A legacy application is trying to connect to a new MySQL 8.0 instance. However, the connection fails with an authentication error. It appears the default authentication plugin used by MySQL 8.0 is not supported by the application's client library."
+  objectives:
+    - Identify the authentication plugin mismatch error
+    - Change the MySQL user's authentication plugin to 'mysql_native_password'
+    - Verify that the application can now successfully authenticate
