Ticket #443 - Deleting attribute present in nsslapd-allowed-to-delete-attrs returns Operations error
    
    Description: commit 90dd9bb3c1411daca353d055d90618e67aa1fa7e introduced
    an Invalid read/write.  The commit meant to allow "on" and "off" as well
    as integer 0 and 1 in on/off type of config parameters.  This patch converts
    the integers to "on" or "off" and pass it to config set function.
