Book: Security Architecture
Revision: 3054cc5
Section: 2.6.2. Component Integration (name of this section may be changed in the future)

This issue follows up on original JBEAP-9345.

In section 2.6.2. Component Integration (name of this section may be changed in the future) there is description of how and when is which principal transformer, principal decoder and realm mapper used. It would be better if this chapter will also include some example configuration and description how some particular "username" will look after every round of transformation and which value will be used for realm mapping, for authentication etc., i.e. which SecurityIdentity, RealmIdentity etc. will be used for.
