    *                      intermittent LDAP connectivity errors   *

    ****************************************************************
    During a search where paging is required to get all the search
    results from the LDAP server, duplicate users can occur if
    there are intermittent errors contacting the LDAP server.
    For example, if page 2 of search results is requested and a
    ServiceUnavailableException occurs andthe request is
    tried again and successfully connects to the LDAP, page 1 is
    re-requested and appended to the results that already contain
    page 1.
    In cases where there are recurring connectivity issues, the
    duplicates could cause a MaxResultsExceededException that
    would normally not be encountered leading to a search returned
    with no results.
