Instances of DirectorySession represent a connect to the Oracle BPM Directory Service.
All components in the Fuego.Fdi module need an instance of DirectorySession to access with the Oracle BPM Directory
Use attribute DirectorySession.currentEngineSession to obtain the current active session used by the ProcessExecutionEngine.
See examples for components DirHumanParticipant, DirOrganizationalRole, DirOrganizationalGroup and DirOrganizationalUnit: they all demonstrate the use of DirectorySession.currentEngineSession.
