I wouldn't worry it, that doesn't work for myself on a Unix domain
member, but these do:

sudo wbinfo --name-to-sid="BUILTIN\Account Operators"
S-1-5-32-548 SID_ALIAS (4)

sudo wbinfo --name-to-sid="BUILTIN\Server Operators"
S-1-5-32-549 SID_ALIAS (4)

sudo wbinfo --name-to-sid="BUILTIN\Backup Operators"
S-1-5-32-551 SID_ALIAS (4)

sudo wbinfo --name-to-sid="BUILTIN\Print Operators"
S-1-5-32-550 SID_ALIAS (4)

And in reverse:

sudo wbinfo --sid-to-name=S-1-5-32-548
BUILTIN\account operators 4

sudo wbinfo --sid-to-name=S-1-5-32-549
BUILTIN\server operators 4

sudo wbinfo --sid-to-name=S-1-5-32-551
BUILTIN\backup operators 4

sudo wbinfo --sid-to-name=S-1-5-32-550
BUILTIN\print operators 4

So the code knows who they are. :-)
