Sure.  But the point is that the SID isn't considered a Windows user so that's
why it doesn't show up by default.  As a work-around for now, you can add a
line like this to your '/etc/passwd' file:

TrustedInstaller:unused:80:544:Trusted Installer,U-NT 
SERVICE\TrustedInstaller,S-1-5-80-956008885-3418522649-1831038044-1853292631-2271478464::

(The above is all on one line)

This will make "TrustedInstaller" show up as the user, just like you will see
in Windows.  The group is still '????????' though.  I'll leave tracking down
the proper SID for the group as an exercise for the reader. ;-)
