Hi
   Let's begin with an example .listed below are the ACE strings for
folder which gives all access rights to a folder.

#define     SC_CONFIG_USER_DIR_DACL    L"D:"\
                                                                     L"(A;OICI;GA;;;SY)"\
                                                           L"(A;OICI;GA;;;BA)"\
                                                               L"(A;OICI;GA;;;%s)"\

"GA"  -- GENERIC_ALL  
"GR"  -- GENERIC_READ  
"GW"  -- GENERIC_WRITE  
"GX"  -- GENERIC_EXECUTE  

So i want rights for 'Modify' and 'List Folder Contents' . For this a
need the corresponding ACE.
