When FDS connects to AD, it will send the dirsync control.  This control 
contains a cookie of sorts.  This basically tells AD to give us all 
modifications since the last time we sent the dirsync control (which it 
knows from the cookie we are sending).  Ad then gives us the 
modifications along with a new cookie to use next time.  You can think 
of this as pull-style replication in the AD->FDS direction.  FDS pushes 
it's changes to AD while pulling changes from AD to itself.
