ITWorx MLG Catalyst error while creating database

While configuring Catalyst School Provisioning tool you sometimes receive an error:
CREATE DATABASE permission denied in database ‘master’.

The problem is that some people get misleaded by the Provisioning Account and start elevating his permissions on the database, but this does not solve the problem. The trick is that the database is created by the SharePoint Central Administration App pool User.

So in order to fix this problem you need to do the following:

1- Check on the IIS  the account that the central administration App pool is using, App pool Identity.

2- Elevate the account’s permissions to DBCreator on the SQL server.
