Can i use chaining between master-slave without having different "ou"? I mean if i have exactly same directory structure and same set of OUs can i still have chaining between master and slave?

Yes.

    You simply should not do that. Read from the master if you have to
    rely on the
    consistency of what you recently wrote to the master.

    No. (Except chaining the read requests of the writing client to
    the master
    which you don't want I guess).
