                               ownership (SIDs) ksmbd generates random subauth

                               values(then store it to disk) and use uid/gid

                               get from inode as RID for local domain SID.

                               standalone server, not a domain member.

                               Integration with Samba tools is being worked on

                               to allow future support for running as a domain

                               member.
