Fix bug 5419: memory leak in ads_do_search_all_args() when enumerating 1000s of entries
The ads_do_search_all_args() function attempts to string together several
LDAPMessage structures, returned across several paged ldap requests, into a
single LDAPMessage structure. It does this by pulling entries off the second
LDAPMessage structure and appending them to the first via the OpenLDAP specific
ldap_add_result_entry() call.
The problem with this approach is it skips non-entry messages such as the
result, and controls. These messages are leaked.
The short term solution as suggested by Volker is to replace the ads_*_entry()
calls with ads_*_message() calls so we don't leak any messages.
This fixes the leak but doesn't remove the dependence on the OpenLDAP specific
implementation of ldap_add_result_entry().
(This used to be commit f1a5405409c396df394611e2a234522572d2860a)
