idsfromsid is a workaround to store unix ids inside SID.

If you want to map real existing SID to proper uids you need to
* setup Winbind on the system doing the mount
* make sure it is able to resolve sid/uid (you can test with wbinfo
utility)
* make sure you have cifs-utils and keyutils installed
* make sure /etc/request-key.conf has an cifs.idmap entry
* mount with cifsacl option instead of idsfromsid
