One of my household IT projects this weekend was to build and deploy a samba4 Domain Controller. I know marginally more than zero about Active Directory, but I am not even exaggerating a little when I say I understand the behind the scenes glue a thousand times better than I did on Friday.
I can’t tell you how to do anything in the GUI, but I can sure as shit manage a GPO with zsh and vim.
(To be fair I have used various LDAPs, was using Heimdal when it was introduced to OpenBSD-CURRENT, but still, I’m rusty on all of it and wasn’t ever an expert. #humblebrag)
