Description:
I created user by following line.
mysql> grant usage on test.* to test@localhost identified by 'test';

You can see wrong password and plugin as this.
mysql> select user,password,plugin from user where user='test';
+------+----------+-------------------------------------------+
| user | password | plugin                                    |
+------+----------+-------------------------------------------+
| test |          | *94BDCEBE19083CE2A1F959FD02F964C7AF4CFC29 |
+------+----------+-------------------------------------------+
1 row in set (0.00 sec)

How to repeat:
Always

Suggested fix:
The password should be in 'password' column.
