grant user privileges

[Hiep Nguyen]

hi all, i have an existing database (internal) with a user named 'admin', 
everything works fine as far as privileges concern.

i just created a new database (test) and want to grant admin's privileges 
on test as same as internal.

how do i do this???

i tried (as root):

grant all on test.* to 'admin'@'localhost';
grant all on test.* to 'admin'@'10.0.0.%';

but it seems not right.

thanks,
