Set ldap.pagedResultsSize to 1000 by default when AD integration is used
Openfire might show weird count of total users if ldap.pagedResultsSize system property is not set to 1000 due to some paging oddity with AD. So maybe it should be set by default in such scenario.
did not cleanly pick onto 4.4 branch.
Looks like most fixes are going into 4.4.1, so maybe this one should also.
