The Database Owner / Password fields in the MediaChase Installer are used to create an account which will subsequently be used by the Commerce Manager to access the database. Note: This account will be created, it does NOT need to pre-exist.
The SQL Admin Username / Password in the MediaChase Installer is used to access the SQL Server Instance in order to create the database and database owner. Note: This account will NOT be created, it should pre-exist and have sufficient privileges to create databases and users in SQL Server. You can also use Windows Authentication as an alternative providing your windows account is an administrator on the SQL Server hosting machine or a Domain Admin.
The MediaChase Installer creates a default super-user account called “admin” (password “store”) to enable you to login to both the CMS site and Commerce Manager. Note: This is purely an ASP.NET membership account, It is not, nor does not need to be, a SQL Login.
I have requested that the Installation Guide on EPiServer World be updated to reflect this information.
We are also working on a smoother deployment experience for the next version of Commerce.
