This falls into the category that we use Samba to provide these services, 
but cannot test and support
every possible configuration. The feature to read the old MS style id 
attributes has not been tested
with Spectrum Scale and is not supported. That said, it can still be set 
in the internal config:

/usr/lpp/mmfs/bin/net conf setparm global 'idmap config DS:schema_mode' 
sfu

Activating this change probably would require a restart of the process 
using this config:

/usr/lpp/mmfs/bin/mmdsh -N CesNodes systemctl restart gpfs-winbind

Opening a PMR on this will likely result in the answer that this is 
unsupported. The best way
to request official support would be opening a RFE, let others vote and 
then product
management can decide on the priority of the request.
