Thanks for quick response, Sahil.
However, as per your request, it looks like I don't have an identity service - what could have gone wrong?
# service identity restart
Failed to restart identity.service: Unit identity.service not found.
The odd thing is that it worked soon after installation. In any case, if you need to troubleshoot the issue via something like TeamViewer, I'm more than willing to make that happen on my end.
