Any advice on handling an array of this size if the LDAP search returns "many" users?

Will the "callback" option of Net::LDAP's search method help? It will allow you to handle the entries one at a time as they are returned. You can build an array, or even serialize them to disk if find out the array is getting large. If you must keep a large number of entries in memory then it may not be worth it.
