I thought your machine was domain joined, so why do you need the local 
machine SID ?

Having said that, 'net getlocalsid' should display the local SID and 
'net getdomainsid' should display the local and domain SID

If that doesn't work, try this:

wbinfo --own-domain

It should display your Netbios domain name, which you can use to get 
your domain SID:

wbinfo -D <YOURDOMAIN> | grep 'SID' | awk '{print $NF}'

Replace <YOURDOMAIN> with the output of the first command.

If you want the computers Netbios name, that's easy, as it is the 
computers short hostname in uppercase:

hostname -s | tr '[:lower:]' '[:upper:]'
