there are 2 databases required a gameserver db and a loginserver db. You can name them as you wish as long as you also modify their names in the config files, right at the start, where it says "database.url = jdbc:mysql://localhost:3306/NAME_OF_DB?useUnicode=true&characterEncoding=UTF-8".(for loginserver config use loginserver db name and for gameserver config use gameserver's db name)
Regarding the loginserver db - gameservers, you type there :
id -> id of the gameserver (this gives the name of the server, Siel...so on. I think you can change the names of the gameservers but sadly i don't know how yet)
mask -> usually this is 127.0.0.1 except when you host the gameserver on different computer, in that case it's the gameserver's ip
password -> here you type same password you assigned to gameserver in the config files
