When running the application, the Login procedure will accept all users defined in the Project Configuration, but additional users, defined only by the system can be included.

The Runtime-users are defined in the database RuntimeUsers defined in Datasets. By default, that database is mapped to a TatsoftDB database. You can select any other database by creating another DB connection and naming it RuntimeUsers (you will need to delete or rename the existing RuntimeUsers row before doing that, as the table does not accept duplicated names).

You can populate that database directly before starting the runtime, or after the project is running, you can create or modify the users with the methods in the Security Name.

See http://www.tatsoft.com/help/fs-2014/runtime/index.html for the complete programming reference on runtime objects

When those methods are executed, the new or modified users are automatically saved on the RuntimeUsers database.
