integrate cae with active directories

im still new in cae. I have a question to ask the expert out there.
I have configured my customer active directories in the cae 8.1. I can browse the properties in it.
But what is the use of integrating the cae with active directories whereby i still need import my devices into the csdb hp zone.
Do i need to import all of them? Pls advise
