This simply means the entry uid=gjakab,CN=Gipsz Jakab does not exist.
Frankly judging from your questions so far you should probably do some basic

improperly described issue to another.

exists. I would like to know why can not find him the query...
Command:
ldapsearch -xv -h <server> -D "<authentication>" -w xxxx uid=gjakab
