Please note that ADOxx implements its own user management, independent from the SQL setup and user management.
When creating the database, ADOxx also creates the default user "Admin" having the password "password" (no quotes). With this user you can log into the ADOxx Development Toolkit, where you can create and manage further users.

For more information, please download the "Getting Started Package" for ADOxx 1.3 UL1 from the ADOxx download page: Getting Started
