a better way to do this is via the "GRANT" command:
http://dev.mysql.com/doc/refman/5.0/...ing-users.html
something like:
GRANT ALL on eqemu_database_name.* to 'the_user_name_you_want'@'the_host_name' identified by 'this_users_password';
that way you create the privs along with the user in question, and they have access to the tables of your database from the specified host (use localhost if you're running mysql on the same host as your emu server).
hope this helps

ps: dont forget to "flush privileges" afterwards or the new login wont be active yet.
