User setup and Roles is standard Mendix Functionality and you shouldn’t deviate from this unless there is a strong reason for doing so. Kindly refer to the following link to understand the App security and User Roles

In case you would still like to do what you are doing, there are two things you would need to do:

  1. You User table/entity must be a specialization of system.User (means system.user must be selected in the entities generalization property
  2. You will need to create an entity called Role and it must have one to many association with your user entity
