B.3.2.14 Ignoring user

If you get the following error, it means that when mysqld was started or when it reloaded the grant tables, it found an account in the user table that had an invalid password.

Found wrong password for user 'some_user'@'some_host'; ignoring user

As a result, the account is simply ignored by the permission system. To fix this problem, assign a new, valid password to the account.
