Ticket #47922 - dynamically added macro aci is not evaluated on the fly
    
    Bug Description: When macro aci is dynamically added and if the aci's
    macro target dn is not normalized, the following operation that requires
    the aci could fail with Insufficient access since matching the target dn
    and the macro target dn fails since the code expects normalized macro
    target dn.
    
    Fix Description: Before setting the macro target dn, process the dn by
    slapi_create_dn_string_case.
