The training version of the platform has some limitations that will affect the execution of some examples provided in the book. There are few limitations and none of them are critical, but they should be mentioned anyway.
In lesson 22 you will create a list of software users. The training version of the platform does not support setting user passwords and using operating system authentication. But this is not vital for studying because you will still be able to run the software on behalf of each of these users. However, users will not have passwords.
Lesson 24 covers data exchange. The training version of the platform will not let you test the second part of the example (the distributed Infobase). But you will be able to fully study the first, more general part (the universal exchange mechanism).
