The fact of you not getting beck anything with large searches may have various 
causes:
* you may have hit an administrative limit on the server (either time or size)
* you may have hit a memory limit in the client
* since your code does not check the result of the search() call there might 
be other problems.

The first cause can be only cured by the server administrator.
The memory issue can be solved by either putting in more RAM into your client 
or you may use callbacks for the search. See the callback parameter to the 
Net::LDAP->search() method and the CALLBACKS section in the Net::LDAP
man page.
