When building a new engined database in proejct mode, recall that users and groups are stored outside the structure file within "Settings/directory.json" instead of the structure file. As a result, newly built apps will not have this Settings folder by default. To transfer users and groups from the original project, copy the Settings folder and move it next to the .4DZ which is located in the directory "{builtAppName}\Database". This will assure that both original and built project will have the same users and groups.
