I will, in a more detailed document.

"Dereference" means take DN-valued attributes, lookup the requested 
attributes from their entry and present the whole thing (name + attrs) 
as the control value.  So

ldapsearch -E deref=member:cn,sn

will return a control value consisting in sequences of member values 
contained in the search, plus the corresponding values of cn and sn.
