I just installed a fresh copy of Ubuntu 10.04.2 LTS on a new machine. I logged into MySQL as root:
david@server1:~$ mysql -u root -p123
I created a new user called repl. I left host blank, so the new user can may have access from any location.
mysql> CREATE USER 'repl' IDENTIFIED BY '123';
Query OK, 0 rows affected (0.00 sec)
I checked the user table to verify the new user repl was properly created.
mysql> select host, user, password from mysql.user;
+-----------+------------------+-------------------------------------------+
| host | user | password |

+-----------+------------------+-------------------------------------------+
8 rows in set (0.00 sec)
I then exit, try to login as user repl, but access is denied.
david@server1:~$ mysql -u repl -p123
ERROR 1045 (28000): Access denied for user 'repl'@'localhost' (using password: YES)
david@server1:~$ mysql -urepl -p123
ERROR 1045 (28000): Access denied for user 'repl'@'localhost' (using password: YES)
david@server1:~$
Why is access denied?
