Mysql – Allowing wildcard (%) access on MySQL db, getting error “access denied for ‘‘@’localhost'”

MySQL

I've created a database and a user, and allowed access via the following:

create user 'someuser'@'%' identified by 'password';
grant all privileges on somedb.* to 'someuser' with grant option;

however, when I try to connect to MySQL I get the following error:

$ mysql -u someuser -p
> Enter Password:
> ERROR 1045 (28000): Access denied for user 'someuser'@'localhost' (using password: YES)

If "%" is the wildcard, then wouldn't it also enable localhost? However, if I do not specify that I want to use a password, then I can connect just fine to the database, which makes no sense because I'm specifying a password when I created the user.

Try connecting with mysql -u someuser -p -h 127.0.0.1.

If you can connect without a password, either you have saved credentials in a .my.cnf or you have created an account that allows access without a password.

If you cannot figure out why you get Access denied, remove from the user table all entries that have Host values containing wildcards (entries that contain '%' or '_' characters). A very common error is to insert a new entry with Host='%' and User='some_user', thinking that this allows you to specify localhost to connect from the same machine. The reason that this does not work is that the default privileges include an entry with Host='localhost' and User=''. Because that entry has a Host value 'localhost' that is more specific than '%', it is used in preference to the new entry when connecting from localhost! The correct procedure is to insert a second entry with Host='localhost' and User='some_user', or to delete the entry with Host='localhost' and User=''.
